I have the 2010 G37x(AWD) and i recently bought the 19s oem wheels for g37 coupe and was wondering what's the best tire size I should get? I'm thinking of 255/35/19 on all 4 or 245/40/19? Or are there other best sizes?

Thanks in advance

245/40r19 is the factory tire size and the ideal width for that rim

Welcome to the site, if those are the staggered coupe 19" wheels just be sure to put the slightly wider wheels in the back. The inside of the wheels are stamped with the sizes, the fronts are 19x8.5 rear 19x9.0.

If you bought the staggered wheels, then front uses 225/45-19 while the rears use 245/40-19.

yeah it's the staggered set but I've decided and am buying the 255/35/19 set, I don't think I can run different tire size. I have the AWD version

Look in the tire/wheel forum. People have been asking your question for years. All you need to know is there. You can indeed run staggered tires but you have to be careful. Read that forum.

You can put a square setup on those rims. The difference in width is only .5"

staggered setup on a front-heavy x will do you no favors and you won't be able to rotate your tires.
