I just purchased a set of oem GTR wheels for my 08 g37 coupe. Im running a set of tein flex coilovers and im wondering the widest tire size i can run in the rear? I see people running 305's on 10.5" wide wheels. Will a 305 fit on my wheels?

 

depends on the offsets. list the full specs of the wheels and I'm sure someone can help you out.

 

20x10.5 i think the offset is +45

 

Or is the front 45 and the rear 25??
