All, I'm shopping for a new Winter tire/wheel set. This is what I understand our cars are, stats wise:
bolt pattern...114.3 x 5
center bore... 67.1
Base model: 17" x 7" and Style/Tech model 18" x 7.5"
I have the Tech model. So I'm considering 2 different sizes for my Winter setup based on the tire calculators also found in this section of the forum as well as what others are buying. Either 195/65 R15's -or- 205/55 R16's. The question is this: are these tire sizes "self-correcting" the 5 MPH overage or am I overthinking the issue? If not, what sizes in the 15" and 16" do I need to go to get as close to an accurate spedometer reading?
For folks who got different ET wheels, did you also have to get new bolts, or were you able to use the stock bolts? I'm thinking about an ET-40 wheel, which would push "out" the wheels slightly...wouldn't I need bolts which were 9mm longer?
