Tesla doesn't have a winter driving wheel & tire setup for P85+ owners. They say the standard 19" winter kit "will work great" (but then why insist that Plus buyers get 21" staggered wheels??), but I don't believe it. If anything, I do not want to go narrower in the rear, so I've been doing some research trying to find a good 19" setup that would work for the Model S that isn't OEM.
First, the OEM specs for the P+:
Front: 21" x 8.5" with 245/35R21 Michelin Pilot Sport 2 tires
Rear: 21" x 9" with 265/35R21 Michelin Pilot Sport 2 tires
5x120 with a 40mm offset & 65mm center bore
My proposed winter configuration:
Front: 19" x 8.5" BBS CH-R wheels with 245/45 Pirelli Winter Sottozero Serie II tires
Rear: 19" x 9.5" BBS CH-R wheels with 275/40 Pirelli Winter Sottozero Serie II tires
Now, my questions for you all:
1) Does this look OK fitment-wise? To my rather untrained eye, all the numbers look OK. The only place I think there's any risk at all is the fender clearance, and that seems reasonable on both.
2) Should I go with 19" for winter use, or 20" knowing that more sidewall does do better in snow?
3) If that 19" setup looks OK, what color wheel do you think would look best with a gray Model S? Here's a photo of my car:
And here are the colors the BBS CH-R comes in (silver, titanium, and black):
I think any of them might look OK, but which do you think might look the best?
