I have a 2004 G35 Coupe with the stock 17" wheels that came with Goodyear RS-A 225/50/17 (25.9") up front and 235/50/17 (26.3") on the back.

I just bought a set of G37S 19" wheels with tires to replace the 17s. The new rims have Bridgestone Re050A 225/45/19 (26.9") up front and 265/35/19 (26.3") on the back. I plan on getting spacers as well.

My question is, can I run the tire size difference without any problems? Thanks for your help.

 

yes. you shouldnt see any adverse affects of the new sizes. I just wouldnt get that same front tire on the new 19s when it wore out. A 235/40/19 or a 245/40/19 would be better up front.
