I feel it is an unfair/unwise policy.
I feel it is a fair/good policy.
I don't feel strongly either way.
It's hard to tell how the performance s will behave with all season tires on, but it really doesnt matter. One should get better times(if only slightly) with the 19 inch wheels with sticky tires because of the weight difference. Wheels only take minutes to swap.
And, yes 5.6 is kind of slow to me. A Newer v8 camaro or mustang beats that easily. I'm used to 9 second quarter mile cars, which is certainly not the norm.
Maybe I'm missing something here, but doesn't the $3500 differential really matter most to those who are buying the non-performance signature model S? The Sig comes with 21" tires and 5.6s speed, so the 21" tires are basically wasted unless going with performance version.
The regular Sig works really well for early adopters who will driver a lot of miles, and therefore the aero tires might make the most sense. That's the $2000 difference mentioned earlier. $2000 is enough to buy a winter set, which would be a nice bonus rather than use all season tires in the snow.
Fortunately I live in California and don't need to deal with snow on a yearly basis, but many customers and prospects do need to deal with snow and rain so maybe the 19" tires make the most sense for those folks. Or maybe just potholes.
On the other hand I agree it doesn't make much sense to get the Perf version then use the 19" tires. But I also suspect you don't need the 21" tires to benefit from the extra acceleration from the perf version.
I have been a reservation holder since the unvieling in March of '09 and had fallen in love with the styling of the Model S from the very beginning. That included the turbine style rims. Not until reading some of the posts concerning the high performance rubber and their less than desireable tread wear did I have any concern. I had no intention of replacing my tires every 10,000 miles. So, I for one would be thrilled if the 19" rims came in the same turbine style. Alas, that aint the case and I REALLY did not want the 19" rims offered regardless of the cost/credit. On the bright side, I checked on Sears.com for the cost of the Continental Extreme Contacts that are currently on the Model S ($219 ea) and found that they carry a warranty of 50,000 miles. That's not to say they will last that long but the warranty does provide for a fair credit based on the condition of the tires and provided they have been maitained (balanced and rotated).
@kvietor, yes the 21" tire choice seems to have exceptional wear ratings. Once I saw the choice and compared to 19" tires... I'll still take the 21s, tyvm.
I feel the same way @Jason S. I have 35 series tires on my car, Michelin Pilot Sport 2's, which are not known for good tread wear. In six years, I have replaced the rears twice, and am ready to replace the fronts now for the second time. That averages out to about 25K miles per set of tires. The rears should last to about 75K miles, the fronts to 90K (30K per set of fronts). I'm okay with that. I'm sure I could run a hardier set of tires all around, but I am partial to the Pilot Sport 2 line at least for this model as they give me the best all-around performance. The Conti's it came with were pretty good as well. I ran a set of Nitto's on my previous M5 and they were a regrettable set of tires. I will go with the 21's and hopefully be satisfied with the wear on them.
If it was the difference between 18 and 19" rims I wouldn't care, but since 21's are not practical at all and the people I know who work with tires all say I should not touch them, leads me to think its a bad idea to make them standard (at least for Canada, where most of our roads are too bumpy). Its not a dealbreaker, but one of those things that may help me to decide whether to switch down to a P reservation.
Thanks for that warranty information. It does offer some room for a bit of optimism that perhaps the Continentals will last more than 10,000 miles.
With regard to rotating tires I imagine that with mirror image turbine wheels on each side of the car that we will have to be vigilent that non-Tesla service technicians maintain the proper right-left symmetry.
NigelM said "If I felt strongly about the wheels/tires I think I'd just get a standard version and then fully load with every conceivable extra". The problem is, it is not possible to fully load up the standard version to equip it like the Performance Production or Signature model.
I can care less about the car doing 0-60 in 4.4 seconds. I have had 4 retina detachments and 5 eye surgeries. My sports car driving days are over. However, I want the upgraded quality leather with the coordinated color piping, and CF trim, and leather on the door panels and lower dash. Plus the alcatera on the seats, etc. These items are not offered on the non-Performance Production model. And the Signature non-Performance model does not offer the solid leather with color coordinated piping. So it is not possible to do as NigelM suggests.
If all these features were available as options for the non-Performance Production model, this whole thread would be irrelevant, as one could do as NogelM suggests. But this option is not available.
As I said before, every rep in the Northeast corridor that I have spoken to, including Tesla personnel in CA, have advised against the 21 inch wheels with low profile tires. My Mercedes SLK350 has low profile tires. About a month ago, a pothole bend one rim. $1,100 to replace it. And this happens too often in this area. Low profile tires result in more rim damage from potholes. It is as simple as that. I am not even discussing that such tires need more frequent replacement. I don't want to be constantly repairing or replacing rims.
