i know some guys that are running a nitto 315/35/17 on their factory 17x9 wheels. could it possible to run 305/35/18 on a 18x9.5 using nittos? i have heard that nittos run a little smaller then other tires and think it could happen just want to get some opinions out there first.

 

Nitto recommends a rim width of 10.0-12.0" for that tire size in the 555R drag radial line. They show a section width for that tire of 12.40". That's the same overall width as a 315/35-17 BFG Drag Radial.
