I have the 2010 G37x(AWD) and i recently bought the 19s oem staggered wheels for g37 coupe, 19x8.5 and 19x9 and was wondering what's the best tire size I should get? I'm thinking of 255/35/19 on all 4wheels since I have AWD, does anyone have a problem with this specs/set on the staggered or?

 

245/40/19 would be closest to OEM tire diameter, the 255/35 is about 2.6% shorter, should be ok but the 245/40 would be the best choice there. Unless you already have those tires or are getting a super deal on the 255s I'd go w/ the 245/40s.

 

no I have not bought the tires yet but my friend really recommend the 255/35/19 instead of the oem size

 

You have 2 19x9 rims ans 2 19x8.5 rims. You can run 245s on both for a square setup without an issue. 255 is to wide for the 8.5 rim and 255/35 is not the proper diameter
