We have no spare tire in both of our car, we found good OEM wheel and tire from a 03 car since the owner put new rim and better tire for his car and selling 4 used wheel/tire for 300 so we're wondering if it will fit out car?

 

All 350z wheels fit all 350Z's

 

both our car has 18 inch wheel, and the wheel he's selling is 17 inch OEM with tire, will this be much offset since our rim is bigger?

 

Stock 17" sizes (225/50, 235/50) are just a tad shorter than stock 18" sizes (225/45, 245/45) but can be used just fine in a pinch (emergency/spare use).

As mentioned, any Z wheel bolts up to any Z33 (only caution is whether 17s will clear Brembo calipers... don't know answer to that.)

 

THANK YOU MicVelo , wish there is a thank button!
