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?
I think any of them might look OK, but which do you think might look the best?
