My 19's are Beyern Multi's and are 9.5" w/ 45 offset. The 285 - 050A's are really wide. Section width is 11.7", Tread width is 10.9".
I have posted that I have heard a "zing" or 2 but can't find any evidence of rubbing on tires or wheel wells/lip. Only has happened when turning at very low speeds over bumps/dips and also has come from front. Maybe 4 times total in 200 mi.
The 275 - 17's are 10.9" section width and Tread is 10.0" based on new RE 760's. Mine are the discontinued RE 750's.
These will go back on GTO. It's in Iowa. Tires are here in FL.
Not sure if I will keep Sport wheels & tires, or if I'll get some staggered 19's.
