Here's a question,
As the performance pack comes with 20" wheels and the 20" Michelin tires, do you:
A - Go with a new forged 20x8.5 wheel, mount the stock Michelins on those and then find 20" winter tires to go on the stock wheels?
B - Stick with stock 20" setup for summer, get 19" forged wheels and tires for winter?
C - Stick with stock 20" setup for summer, get cheap 19" wheels because it's winter and no ones is outside to look at your car anyway?
D - Get forged 20" wheels and sell the stock 20" wheels, do whatever other option you want for winter?
Tesla's 19" winter tire package is $3500 and it sounds like this group buy could net a new set of 19" (maybe 20") wheels and winter tires for less than that.
But why would you want a set of forged wheels for winter use over summer use?
