What sup guys, I'm about to buy some used wheels with some tires on them, the specs are:

Fronts:
20" x 9.5 +45 offset
255/35/20 tires

Rears:
20" x 10.5 +25 offset
285/30/20 tires

After using the Tire Rim Calculator The Diameter difference is -0.3" (-1.10%)


I was wondering if I could run this set up on my G37x without causing any problems?

 

Are you bagged? Those specs are pretty aggressive for the rear. Unless your are slammed and don’t mind running some camber.

 

fronts will work, rears will be poking over an inch outside the fenders, if they were +45 instead of +25 they would work, and front tires should be 245/35 for best diameter variance. Save those wheels for the coupe guys, not worth the work to make those fit.
