GetAmped I have a confirmed P85D order for a December delivery. Wanted to get S owner perspectives on running with the mandatory 21 inch rims for both summer and winter. I am in the Toronto area and plan on driving the P85D as a daily driver plus road trips on most of the Eastern Supercharger routes in all seasons (major snow). In reading the postings there seems to be a lot of P85 and P85+ owners that are running on 19's for summer and winter.
Should I be worried about being locked into only 21's on the P85D with respect to bent rims/flat tires etc?�
Oct 17, 2014
Bighorn There's a 19" winter wheel option on the order page. It's been a more sensible choice for my P85+ in WY. I've had no trouble running the staggered 21s over 20,000 miles now, coast to coast. It's nice that they're discounting the winter package--I went with TireRack when Tesla was charging $4K for the set.�
Oct 17, 2014
GetAmped The Tesla sales team is staying that the Website is incorrect and all P85D's can only use 21's.�
Oct 17, 2014
Cottonwood The P85+ could wear 19's in a winter outfit, and except for the front motor, the P85D is supposed to be very similar. My local sales/service team is somewhere between "we don't know" and leaning towards "19's will work fine." It's a big question, but if the P85D can't wear 19's then I will be ordering an 85D instead. I must be able to put hard-core winter tires like Nokian Hakka R2's or 8's on for my winter conditions; stopping is a bigger deal than starting...�
Oct 17, 2014
svp6 My modified p85d order includes the 19"winter set. I have not been told of an incompatibility. Did you hear this directly from Tesla central ordering or from local store?�
Oct 17, 2014
hiroshiy I'm not a car mechanic, but what would be the technical reason to lock into 21s? I thought any rims/tires would work as long as it fits in wheel wells and allow brakes to work without hitting the wheels...�

As someone who thoroughly enjoys (but misses) a couple of feet "dump" and (like you) has another vehicle with dedicated "snows" and chains, your very important point is often overlooked by novice AWD passenger vehicle owners/drivers.�
Oct 18, 2014
GetAmped I heard this on two occasions from the Tesla central ordering center. The local team could not confirm.�
Oct 18, 2014
HankLloydRight This. I'm sure the P85D isn't "locked" into 21" rims. I think that any SA or Tesla employee saying that is either guessing or misinformed (also not uncommon). Sure, for ultimate performance stats you may need them, and maybe that's why they are saying you need 21" rims.�
Oct 18, 2014
Cottonwood The only reason that I have heard that the P85D may require 21's is if the brake calipers were larger and would not fit inside 19 rims. That being said, as far as I can get info, the suspension/brake/wheel setup on the P85D is the same as the P85+ and 19's should fit on the P85D.�
Oct 18, 2014
HankLloydRight I guess that's a possible reason.. We'll just have to wait until someone tries on their 19"s on their PD. But I personally doubt that's the reason.�
Oct 18, 2014
Denarius The sales team has probably been told you have to order the P85D with 21s, which is true. That doesn't mean that 19s won't fit, the fact that the order page allows the purchase of 19" winter tires confirms 19" wheels will fit. Just like you couldn't order the P85+ without the 21" wheels, but my 19" wheels fit just fine.�
Oct 18, 2014
ArtInCT The only reason I can think of to omit the 19" rims would be (as mentioned earlier) that the brake calipers are dimensionally WIDER and would hit the spokes on the 19" rims. Pretty easy to find out IF you had a rim and a P85D. The service center would perhaps know of the part number on the calipers on P85D are the same. They may not have access to the P85D parts list as of yet however. The design center DOES indeed allow you to order the 19" winter tire set with the P85D as an option. An error?
I wonder if the 19" winter tires are SPEED rated for 150MPH? That may be the issue in a nutshell... anyone know?
(BTW, noted this AM that the design center has a picture of the P85D interior with the new seats.... the link is in the seat option box (which says only BLACK).
Also noticed that the PRINT function is now back you can print your configuration out. It was missing since the D website upgrade.�
Oct 18, 2014
GetAmped Cottonwood,
What rim size and tire do you use for the summer?�
Oct 18, 2014
andrewket I've been running 19's on my P85+ for awhile now. I haven't had any issues. Assuming the P85D uses he same suspension, it shouldn't be a problem.�
Oct 18, 2014
andrewket I can't find the print function? Only "view profile" is listed.�
Oct 19, 2014
Cottonwood I have three sets of wheels and tires for my P85:
- 21's, dark with Conti's that I use for special, warm, high performance days.
- 19's, silver with Michelin Primacy's for everyday, 3-season driving.
- 19's, sliver with Nokian Hakka 7's for 3-5 month hard core winter driving. When these wear out, I will get some Hakka R2's to replace them.
With a floor jack, breaker bar, and torque wrench it only takes 10-15 minutes to change wheels at home. I have a few of these for storing wheel/tires in the garage: TireRack.com - Tire Storage Rack�
Oct 19, 2014
andrewket I have the same tire rack. I mounted it fairly high on the wall. I find that lifting the wheel and tire while on a ladder is down right scary. Are you doing anything different? I thought about trying to rig up a pulley system.�
Oct 19, 2014
AMN Tesla is shoving those 21s down our throats because they have a crazy margin on those wheels. The car doesn't need wheels of that kind of diameter, especially when it's this heavy.
Staggered setup is 90% marketing/premium product differentiation, 10% function.
I may get 20" HREs down the road in the same size front and rear, so they can rotate if needed.�
Oct 19, 2014
Cottonwood I'm a little over 6 feet tall, and can just reach getting the tires up and down standing on the floor in my garage, but yes, it would be very scary to handle the Tesla wheel/tire combos standing on a ladder. As it is, I have to do a nice, clean, dynamic move from the floor to the rack to get them up.�
Oct 19, 2014
Taipan In Europe, you can NOT order the 21s Winter Wheels, only the 19s, when you order the P85D.
Model S Design Studio | Tesla Motors
I guess that confirms that whatever version you order, 19s will fit, winter or not.
Also, when you look at the Specs page on any EU site, you'll see no difference about calipers or disc sizes which could prevent 19s indeed.
My take is this is just some monetization trick (like the one about having to order the panoramic roof to be able to install a roof-rack).
Plus a real pain in the arse if you blow a tire on a week-end trip: 19s tires are already not often "in stock" at the local shop but getting a 21s ? You'll be AWOL for some days just waiting for the delivery ...
E.�
Oct 19, 2014
Cottonwood I got this question as a private message and thought others would be interested, so I am answering it in the thread.
It's pretty simple. My 21's came with the car; I bought the 19's with the Nokian snow tires from Tesla in Fall 2012 (Tesla does not offer that combo now), and I bought the other set of Tesla 19's without TPMS from another owner via a TMC ad. I got the Tesla compatible TPMS's along with a set of tires from my local Discount Tire store.
Once you have the correct size wheels with the correct size tires, and the correct TPMS, then all you have to do is put them on the car and use the "learn TPMS" command on the 19" screen.�
Oct 19, 2014
Lloyd I just yesterday mounted 19's with Michelin PS3's for my winter tires in California on my p+. Hoping for lots of itwe need it desperately!

Oct 20, 2014
yobigd20 let alone the margin on the wheels are purchase time with the car, after purchase Tesla is making a KILLING on the 21" tire & rim replacements at all the service centers. I've yet to go to a service center that isn't SWAMPED with model s's lined up there for rim/tire replacement. the margins on these are what pay for the operating costs of the service centers. there is no incentive for tesla to do anything about this. they'd lose a lot of money and probably wouldn't be able to afford to operate the service centers if they didn't keep shoving those 21s down everyone's throats.
as to the OP, i'd be running 19s both in winter AND summer, especially given your location. sell your 21s as soon as you get them and downgrade and put some 255/45ZR19 Michelin Pilot Sport A/S 3's on. They'll have plenty of grip for the P85D under full accel. And you won't break your bank account either for tire/rim maintenance.�
Oct 21, 2014
commasign Just spoke to my local SC. They are being told that the 19" wheels will NOT fit the P85D due to the larger brakes/rotors. They are saying (as others have noted in this thread) that the website is in error allowing folks to select 19" winter wheels. I'm really hoping that's not true. Guess we'll all find out soon.�
Oct 21, 2014
yobigd20 Oh man, if that's true then Tesla is set to make a fortune on tire and rim replacements!!!
Wait a minute, why are the 19s available for S60D and S85D then? Are the brakes/rotors any different?? I thought they were the same for all models which would mean they are feeding you BS�
Oct 21, 2014
commasign Good question. Wish they would provide clarity on this. I don't understand why the brakes/rotors would be any different than the P85+ and we know that car fits 19" wheels just fine. If 19" are compatible, then I'm dumping my 21" at delivery.�
Oct 21, 2014
Cottonwood If 19's are incompatible with the P85D, then I am switching my order of a P85D to an 85D.I like summer performance, but being able to mount serious snow tires like the Hakka R2's or 8's for winter driving is a priority for me.
�
Oct 21, 2014
andrewket This better not be the case as I just sold my P85+ with my silver 21" wheels and a spare, and kept my after market 19's.�
Oct 21, 2014
Chuck P85D dude... we get it... YOU DON'T LIKE THE 21" WHEELS. but give it up, man... you are like obsessed with this.
i have had 21" wheels for two years now and they have been great. tire wear has been fine and no bent rims. look great, perform great.
you are displaying elements of solipsism. get a grip. YOUR experience does not equal EVERYONE'S experience.�
Oct 21, 2014
dsm363 Over two years with 21" rims. Other than tread life from summer tire compounds, no issues.�
Oct 21, 2014
yobigd20 I don't have any personal experience with the 21s. I was smart early on and preemptively downgraded for free before I got my car based on the reports from 2012 owners that were getting killed financially from them. I'm simply just relaying the dozens if not hundreds of instances from people on the forums and local owners I know that's had multiple incidents with their 21s plus all the service centers I've been to (Norristown, queens, Springfield) all swamped with 21" tire and rim replacement vehicles. Everybody that I know that had 21s now has 19s. That's pretty significant and speaks for itself. I don't know anyone who HASNT had a problem with the 21s (except for you apparently). There's people on these forums that have had 4 tire / 4 wheel replacements within weeks of each other.
It's important to educate future owners about this so they are not slapped in the face with $2k bills a week after getting their cars. Most people are completely unaware of all the problems with driving on the 21s. They just buy the car with all the bells and whistles not realizing the maintenance nightmare and income hit they just set themselves up for. Again most ppl I know that had them are like "why didn't someone tell me about this before I bought the car, it would have saved me thousands!!"�
Oct 21, 2014
Chuck P85D so you have ZERO experience or firsthand knowledge about the 21's. but you have accepted the position of advocate for a few 21 owners who have had bad experiences.
well come back to reality. i have had no problems with my 21's in two years/20k miles. i just replaced them at 17k on my P85. not unreasonable for the performance i got. and i knew that going in.
there are LOTS of other 21 owners who have no problems as well.
you need to remember that you are getting a bit of a skewed reality if you are only paying attention to people who complain on internet message boards. 95% of satisfied 21" owners don't come on the internet to share how pleased they are with their purchase, you know?
it just seems to me that you have no personal knowledge of what the 21's can or can not do. you are relying on here-say and others' experiences, and have adopted them as your own. I would suggest you stop. you are becoming a one-note Charlie. if ACTUAL 21" owners are so infuriated by the wheel that they feel they need to go on a crusade to educate others as to their evils, fine. but coming from you, it's disingenuous and (at this point) REALLY GETTING OLD.
find a new bell to ring.�
Oct 21, 2014
Xenoilphobe There are five p85s in my neighborhood. 4 have 21s and 1 has 19s. All 21s have been stranded with flats due to pot holes here in DC/NVA and many have switched to 19s. My 19 has gone 23k with no issues.
While I like the look of the 21s. The risk is too high with no spare as my daily driver and costs are high for what you gain ( in my opinion).
I'm considering the p85d, but will have to explore other options than the 21s and may downgrade to the s85d instead.�
Oct 21, 2014
Chuck P85D 1 - i live in the same area and have had no problems with my 21's. when i drive, i personally try to NOT hit the potholes. call me crazy, but my strategy has worked wonders so far.
2 - the potholes were really really bad last winter. they busted all kinds of rims and tires on all kinds of cars all winter long, wheels much smaller than the Tesla 21's or even the 19's..�
Oct 21, 2014
AMN 19" winter wheel set shows up as an option for P85D, so I am sure they will fit. I just checked, it's a $2,500 add on. Not a bad deal, actually.�

GetAmped P85D conflicting information on ordering with 19 inch Winter rims
Re-posting this conversation here under "Ordering" as this is something impacting ordering for many people:
I have a P85D confirmed with a Dec delivery and plan on driving to Blue Mountain (local ski hill) for skiing and generally driving on all types of roads including likely un-avoidable potholes and other road imperfections that I won't be able to see and avoid because they will be filled with slushy snow in the Toronto, Canada area. I really just want the best owner experience balancing needing the correct tires to deal with the torque/regen and my desire to not have tire and rim issues.
The following summarizes the rim size ordering confusion for the P85D:
1) I called the national sales group (Tesla HQ) to change my P85 order to a P85D. When walking through the options with them, when I came upon the 19 inch and 21 inch options for the Winter tire packages, although I wanted the 19 inch package the rep told me I could not order with it and must order the 21 inch Winter package.
2) in my other post under "Driving Dynamics " where I was questioning this 19 versus 21 use of rims, many forum members with confirmed P85D orders are stating that they have successfully selected 19 inch winter packages.
3) Forum members from Norway are stating that when they configure the P85D they can ONLY order with the 19 inch rims for winter.
4) Forum members with P85+'s are all stating that they run 19 inch rims for both summer and winter on their cars without issues. They point out that when they ordered the P85+ that they had the same mandatory 21 inch rim requirements but changed to 19's even with the Service Centers mounting them on their P85+'s.
5) every subsequent time I call the national sales group the agents answering always state that even though the P85D can be configured on the website with 19 inch rims for the winter package, they say that they will notify people ordering of the mandatory need to use 21 inch rims. I have called at least 6 times always with the same answer.
To improve on the ordering consistency, what do we need to do to get the correct answer and what is it? Can someone from Tesla answer this "Can we use 19 inch rims for summer and or winter on the P85D?�
Oct 22, 2014
yobigd20 But the poster said that Tesla said that was a mistake on the web site and 19" winters aren't supposed to be offered for the P85D.�
Oct 22, 2014
yobigd20 You're not the only one. One person talked to 6 different Tesla employees and were told by all that 19s will not fit on the new P85D. Thread here: P85D conflicting information on ordering with 19 inch Winter rims�
Oct 22, 2014
andrewket I just re-asked this question of Tesla via email. I will report back. If the answer is that the 19's are not compatible, I may have kept my P85+. No joke.�
Oct 22, 2014
sandpiper
Odd. I have a confirmed order with 19" winter rims on a P85D ( in Canada). Nobody raised any questions. I really really don't like the 21" rims. When I get the car I'm going to try to sell the 21" summer rims and replace them with 19 inchers. There are just too many potholes in this area.�
Oct 22, 2014
yobigd20 I think you need a change.org petition to demand that 19" wheels fit for a P85D.�
Oct 22, 2014
stevezzzz Talked to a new owner with a P85 running 21's, at the Silverthorne SpC: he'd had the car less than a week and had already had to replace two rims and all four tires from one unfortunate run-in with a pair of perfectly spaced potholes.
I get get it that some careful/lucky people have never had a problem with their 21's, but the horror stories are real, and numerous. Problems with the 19's, anyone?
<crickets>�
Oct 22, 2014
yobigd20 nada. I've yet to come across anyone that experienced a blowout or bent rim with 19s. and there are A LOT more 19s than 21s driving around. that's very significant. I'm sure there are some, but the % is negligible at best. there are , however, cases of 19" tires needing early replacement due to wear, but that is 100% alignment problem which all models are susceptible to.�
Oct 22, 2014
AMN I am 90% sure, the suspension geometry on P85D is identical to P85+ which is perfectly fine on 19" wheels.
If the diameter of the brake disk didn't increase, P85D should be fine with 19" wheels and Tesla is just making money by forcing us to buy those high margin 21s.
I may cancel our order and keep our P85+ if I can't put proper snow tires of reasonable diameter on it. I may entertain 20s but I am not driving it in Minnesota winter on 21" wheels.�
Oct 22, 2014
JohnQ So, from a purely technical perspective, why would the P85D require 21" wheels? Other than the brake clearance issue if it exists?�
Oct 22, 2014
JohnQ Sure, I slightly bent one rim and had a sidewall bubble in 25k of driving ... but I ran over the damn curb. That was with two wheels and only one got bent (very slightly). Car drove fine on the way home, I only noticed when I switched to my snows.�
Oct 22, 2014
sataponw I emailed Tesla and asked and he said that the 19 inch will fit P85D. "The only reason we require the 21� for summer is because we need as much rubber on the road to put down the 691 horsepower."�
Oct 22, 2014
Trnsl8r My impression was that the anti-spinn system on the Model S was so sophisticated that it should be able to adjust...�
Oct 22, 2014
dsm363 A lot of it matters where you live. Some parts of country have decent roads so 21" rims less of an issue. Tesla should have a 19" performance tire option though.�

yobig,
Please continue to spread your direct, accurate information about this topic.�
Oct 22, 2014
Denarius I've had no issues with my 21s. I've had 3 flats (all due to punctures) so they had nothing to do with wheel size. My only complaint is the extremely limited options in the staggered size (265/35/R21) on my P85+.
That being said, if I had the option I would have ordered 19s.�
Oct 22, 2014
svp6 I also specifically asked my local Tesla reps and I was told 19" winter is going to work with P85D.�
Oct 22, 2014
yobigd20 tire size (19" vs 21") has nothing to do with this. the contact patch difference between the two is not that much. a proper 19" tire that has enough grip is more than sufficient for the 691 horsepower. besides, the rear motor size didn't change at all in the 'D' model and my aftermarket 19s are more than sufficient for my P85 at full accel. if anything, in the 'D' model the torque should be slightly more distributed so that's even less of an issue in the 'P85D' vs the 'P85'.�

sandpiper So.... that makes no sense. You could order a P85 with 418 in the back on 19s. As far as I know, the rear motor hasn't changed. They've just added a front motor. The rears don't care what's up front.�
Oct 22, 2014
GetAmped On Wed Oct 22 at 1:40pm (Eastern) I spoke with Max Paris at HQ Sales that told me again like all other HQ Sales reps before (re: my other 6 calls) that people are ordering with the 19 inch winter package selected via the USA and Canada configurator, however he has been told that when the VIN�s are assigned, the configuration teams will not allow the 19 inch winter package to be ordered and will contact customers to force a change to the 21 inch package. I told him about the feedback from user in Norway indicating that in the configurator they can only select the Winter 19 inch package, however Max could not comment as he did not know about this and said the Website needs to be updated.
Max said he has opened a case with the configuration team to request the change from my order of the 21 inch Winter Tires to instead be the 19 inch Winter Tires. He said he feels that they will not allow it and will call me in a couple of days to let me know the decision. If 19's are not supported on the P85D I will be changing my order to a 85D (assuming 19's are supported on them, lol). Stay tuned for the response from Tesla. Everyone please call them and email them if this concerns you...�
Oct 22, 2014
HankLloydRight And we've again proven just how much misinformation one can get from Tesla employees.
Don't get me wrong, most of them are great. But when given a question like this, I think many of them just answer off-the-cuff with answers like "we need more rubber on the road".
<rant on>
I have a pet-peeve when employees of companies make up their own "policy" on the spot instead of admitting they don't know something and taking 5 minutes to go ask for assistance from a manager or owner. Years ago, I once got into it with a bank MANAGER where my car loan was, trying to explain to her how simple-interest loans work. She had some other ideas about it, I have no idea how she got to be a bank manager with such limited knowledge of simple car loans. Things like this are really bad when limited intelligence employees are in a position of authority or power, and make up store policy on the spot, and when you challenge them, they get all defensive and offended. Happens all the time. </rant off>�
Oct 22, 2014
HankLloydRight I bought an inventory P85+ car with 21" wheels, so I didn't have the choice to order 19"s. I love the look of the 21"s (in the summer)... so instead, I traded out my 9" rear wheels for 8.5" rims, and then put on 245/45/21s all the way around. Cheaper tires, matching sizes, able to rotate them. I don't notice any difference from the 265s.
I also haven't had any problems with the 21"s wheels in the greater NY area (I've owned since March), but I also drive with one eye looking for and avoiding potholes.
I also have 19" TSTs for winter driving.�
Oct 22, 2014
andrewket I went with 19 TSTs for summer, and tesla 19" for winter. Btw, the 245 Michelin tires will fit the 9" rims. It's within spec (I was surprised myself).�
Oct 22, 2014
sundoc So let me add this:
My DS called back today... he states that there is absolutely no problem running the 19's
I also just spoke with the Cali tesla ppl... had called earlier then realized that the west coast was still asleep. At first the sales guys said that the 19's can't be used with the P85D and that it had to be the 21's. I advised him that our winters up here in the North wouldn't take too kindly to the 21's and asked if there had been a change in the brakes/calipers etc. I also said that the European orders apparently have no winter 21 rim options. Then he replied that the 19's can fit but the engineers are advising against it due to torque handling issues...
So in a nutshell. The 19s will fit but the engineers advise against it.�

Oct 22, 2014
Cottonwood I just got an e-mail from Tesla Fremont as a result of sending questions in a reply to their "Welcome to the Tesla Family!" e-mail after my order:
Thank you for your message and your amazing support. We are truly blessed to have great customers like you.
... It will be possible in a couple of days (I expect before the end of the week) to select 19� wheels for the P85D, rather than the recommended 21� (there will be an associated credit). Additional interiors colors, besides the black, will also be available.
...?
This looks great for 19's and for my desire to have an interior that is not black.�
Oct 22, 2014
dsm363 Assuming the rubber compound was the same wouldn't traction be identical? Sure handling might be better with 21" rims and shorter sidewall but traction should be same (I think).�

HankLloydRight Yes, it's well known that 21" wheels do perform better than 19" wheels, but that difference is really at the edge of performance/handling. Skilled drivers would be able to tell the difference. Everyday drivers? Probably not so much.
Yes, more rubber does equal more grip, I don't think anyone is arguing that. But in this case, the difference of "rubber" between 19" and 21" is marginal (assuming the same width tires). They'll both have essentially the same contact patch size. The diameter of the tires on the 19" and 21" wheels should be essentially the same, therefore, the same amount of "rubber". That's why the excuse of "more rubber" is clearly just misinformation/misunderstanding.�

HankLloydRight Also, do we need two nearly identical threads talking about this?�
Oct 22, 2014
andrewket I agree. Mods, I vote we merge.�

andrewket I just received a call back from Tesla. The 19's will fit, but they are strongly advising against it, more so than on the P85+. The suspension and the stability of the car is designed around the firmer 21" wheels.
The person I spoke with is located at Freemont and specifically went and spoke with someone in engineering before providing me an answer.
So.. Take this for what it's worth. Personally, I'm likely still going to put my 19" TSTs on.�

derekt75 It's widely assumed that 21" wheels perform better.
but is this assumption correct?
19" wheels will most likely perform better than 15" wheels, but at some point the sidewall flex becomes irrelevant and the weight of the wheel starts making a bigger difference. Look at the tires on high performance racing cars, and you'll see that they're not rubber bands.
This thread indicates that 19" wheels are likely to perform better than 21s (assuming the same rubber compound).�

P85D conflicting information on ordering with 19 inch Winter rims

commasign Jerome, the VP of sales just to replied to my email:
"Thank you for your note and your order of a Model S.
We will be introducing additional wheels for the P85D (although we do recommend the 21�). Jessica, whom I have copied on this message, is based in Rocklin and will be able to help you with the modifications."�
Oct 22, 2014
HankLloydRight Would be great for them to offer a P85D- which is the P85D without the "P85+" options (21"wheels, suspension upgrades, slightly less performance, lower price).
A man can dream.�
Oct 22, 2014
Denarius I want the suspension, just not the staggered wheels.�
Oct 23, 2014
andrewket Wow Tesla really can't get their communication right. This contradicts what I was told last night by someone in sales in Fremont. I also had an exchange with Jerome about this last week. No mention of other wheel options at that point, just the alternate interior color options. This must be a very recent change based on customer feedback. Good! I told him about my experience with the 21's, and suggested that if they offered a turbine look 19" wheel in grey that I thought it would sell.�

SCDrJ 19" wheels now are an official option in the Design Studio.
Takes $4,500 off... Still a bit of $ over S85D, but I am getting tempted... 21" was my #1 reason not to buy.
2 days left before auto-confirmation... What to do, what to do?�
Oct 24, 2014
GetAmped I was going to downgrade to a S85D if Tesla did not allow the 19" wheels on the P85D. I am re-confirmed today for 19" Silver Cyclone's for Summer (Did not expect this) and the 19" Standard wheels for Winter. Looking forward to the December delivery and a little more peace of mind in our pothole and blizzard country.
Note: This shows the power of the Forum for focusing user feedback for the powers to be at Tesla HQ to make positive decisions for the benefit of the brand. Go Tesla!�

yobigd20 I just wonder how much Tesla's changes are due to either
1) their web developers just suck and leave things out or they are rushed to get something up ASAP so they take shortcuts and leave options out
or vs 2) if this wasn't planned and this is just Tesla's reaction to a bunch of pissed off customers
or vs 3) this was intentional by Tesla and their strategy was to capture a higher margin on the initial glut of people that ordered/upgraded to P85D's and then change it later to show all options and hope that people don't downgrade.�
Oct 24, 2014
Cottonwood I was in a similar situation.
Be careful of the stock Tesla snow tires, from everything that I have read, both on and off of TMC, they are more focused on winter dry road performance than snow performance. See Time to Shop for Winter Tires - Page 8 for a direct comparison by a fellow Canuck. I'm going deal with finding rims, and get the Nokian Hakka R2's. I have the Hakka 7's on my current P85, but the stud noise drives me nuts, and I do not have many "wet ice" times in Colorado where studs are an advantage.�

Kandiru S85D future owner, and sorry for trolling, but I posted similary on another thread..
The best solution IMHO (just a Golf R, S60R, Turbo X, S4 owner here) is:
1. Order the car with 19" standard wheels. Reason is you need ET ie offset of 40mm
and the TireRack plethora of 19" wheels have 32-25mm offsets making the risk of
caliper bruising and rotor warping if not worse real, while their 40mm wheels are over
$500.
2. Order Dunlop WinterSport German made winter tires and swap them at local
shop. Even better, have the local shop quote them for you, some cut under TireRack
and also the boyz at the shop will be happier.
Sell the 19" OEM rubber.
3. Order 21" grey Taiwanese turbines with OEM Michelins and TPMS for 2k less than with
car on TireRack.
You have an aggressive summer setup and a great winter setup with few spokes and silver
hiding curb and debris rash a lot better, all for less.
Finding a very decent tire shop is key, the grease monkeys at my local small town
shop know their trade in and out.�

HankLloydRight
Or, as a lot of us did, order the Tesla 21" Turbines with the car and OEM rubber for summer, and for winter buy the 19" TSportline TSTs especially made for the Tesla, no offset adjustment needed. Perfect fit, and uses the stock lug nuts and center caps. Put on whatever your choice of winter rubber you need.
I'm not sure many people would trust the Taiwanese 21" rims to be up to the same specs as the OEM 21" Turbines.�
Oct 27, 2014
Kandiru Through my years with the RC hobby, and garage, I have had many Taiwan tools and they seem a notch above mainland, generally speaking.
I love my Niko auto tools for example, their torque wrench matched almost to 1 lb/ft to the shop digital one at the Audi dealer.
Of course, if I had a choice, BBS, Borbet, or O-Z would be first.�
Oct 27, 2014
Seven7 I bought one of those rims from tire rack to use for a spare, they look very close but the outside edge of the rim is different, when I took the center cap out I couldn't help but laugh at the inscription on the back "Model-S" seems like they copied it as close as they could.
