Do you have to do any up grades to the computer or any thing else.

 

shouldnt have to but if you have a tuner you can update the computer to recalibrate your speedometer and transmission shift points. Nitto also makes a 285/75r17 with is a 34x11.5r17 which is a cool size (thats what I have on my truck and they are awesome!)

If you have a 4x4 and want to go over a 33" tire you need to add at least a leveling kit to avoid rubbing. Can you provide details on your current setup?
