Hey guy's my friend has ADR M Sport 18" Rims on his 350Z. His tire size in the rear are 255/35ZR18 and the Front are 235/40ZR18. When he bought the car 2 years ago it came with these Tires and Rims and he messed up 2 Rims. One in the front and the other one in the rear. Can you help him out and tell me what Rim size he should get to fit the Tires, (18 x 8.5 or 18 x 9.5?) . Thank You!

 

Those are Staggered wheels, you need 18 x 8.5 in the front and 18 x 9.5 in the rear.
