So I picked up a set of 350z staggered wheels that I believe are 18x8 in the front and 18x8.5 in the rear.Im planning to run these in my 04 sedan and I’m trying to see what tire size would fit the wheels.Any ideas?

 

225/45 r18

 

widest for the 8.5 width wheel would be a 255 before you start stretching the tire, front you could run a 225-245. I'm not sure what will fit correctly on the sedan without rub but these are the sizes you could run. ran a 245 up front and 255 rear on 19 rays on my 37 sedan, but I know fittament is different on the v35's.

 

could I run a 225/45 in the front and 245/40 in the rear?

 

yup, I believe that is what most people run when they have the rays.
