I have a 2008 pro4x, question is will a 325/50/22r fit under factory height? i know 24's will go on a titan from factory because i have alot of friends that have them, i know this is a big tire so i'm curious if anyone knows if they will fit? thanks.

that is about a 35" tire so you will need at least a leveling kit and it will depend on the offset of the wheels
