i am rollin on 350z rims. Need new tires and dont know what size i should get. Have 235/35 now, but stock size is 245/45. HUGE DIFFERENCE. 235/35 are too low pro since i live in the country. They are the staggered setup. Anyone else running these OR other sized 18's?

 

225/45/18's?

 

i'm runnin 225/40. they clear fine

 

When I had Dodge Magnum 18's on mine the front had 225/45 and the rear had 245/45 with no issues at all. I could've even fit the 245/45 on the front.

The factory tire size for these trucks is 195/75-14 (25.5"), to stay the same overall height you need a 235/40-18 (25.4") or 225/45-18 (25.9").

A very good tire calculator link burnzya showed me....

those magnum wheels, are they steelies?

 

Nope, split 5 spoke

 

how wide is the wheel? 245/35 is still a nice thick tire. but if you need more meat then do a 225/40.

i like wide looking tires better than thick sidewalls. Sometimes im thankful for big sidewalls, Then i make a fast turn.....
