In Reply to: Buying New Rims Need the right size for 18" "HELP" posted by Brian on February 27, 2001 at 09:10:33:

If your goal is to maitain the same overall wheel & tire diameter to avoid affecting the speedometer, use this site to calculate the change.

I went from 225/50/16 all around to 225/45/17 on a 17 x 8 wheel up front and 245/40/17 on 17 x 9 in the rear. This was very little change to the overall diameter and filled in the rear nicely. Ride comfort was maintained, handling improved and I have little fear of blowing out a sidewall in a pothole. As you go up in wheel diameter, sidewall height will have to reduce to maitain overall diameter. As you go too far up in wheel size, comfort will reduce (how much you care about this is up to you), and sidewall blowout risk increases.

I know people happy with 19" rims (D'ub y'all) and the compromises associated with it. I know others who only want 16" with a 50 series tire.

How are you using the car? Wheel weight may be an issue if you plan to AutoX. It's hard to go far up in size and keep wheel weight down.
If your just stylin' weight may mean very little to you.
