Anyone running 13.50's with a 6.5 in Pro Comp lift on an FX4. I know 37 x 12.5 will work however I want to run Nitto Mud Grapplers and they don't make a 37 x 12.5 x 17 size tire. Any input you have would be great.
Worse case is you'll have to adjust the steering stops a little to compensate for the extra width. I really don't see any reason they won't work if a 12.5 wide tire will.
I have a 99 f350 crew cab longbed, I am running a 6 inch tuff country lift and 37x13.50 17 they rub at full turn on the leafs but not during normal driving. dont know the offset to the wheels but they are 17x9 . i have toyo open country m/t now i had mud grappler but wear to fast and make way to much noise gets old after awhile
