I have some forged Sevas R55 on my G37s that I will be parting with soon. Specs as follows

Front 20x9 offset 32
Rear 20x10.5 offset 26

I love them to death, but they keep leaking air through the bead, and I think its cos I am running 275's in the rear, when I should be running 285's (which I can't cos they rub like a ****). I know people commonly run 275's in the rear on 10.5" wheel, but I seem to be having an issue. The tires I have are Falkens...anyway. I was wondering if these offsets would work on a G35 Coupe. I have seen some crazy offsets for coupes, so I am assuming it would be fine for them to run these wheels with 285's in the rear. Any info would be appreciated...

 

those offsets would look wack on a coupe. the tire size isn't your problem

 

thanks for the reply.

 

It might be due to the air valve that is a common problem.
