I have an 07 crew cab 4x4 with a 2" rough country leveling kit. I'm currently running 275/65/18 nitto terra grapplers on stock rims. I'm in the market for new tires because these Nitto's are wearing super fast. Any ideas as to how much bigger tire size I can increase on stock wheels without having to cut too much or any scrubbing.

Thanks

 

LT275/70R18 would be my suggestion

 

This ^^.

 

If Id had an 18" wheel that's the size I woulda gone with .. I have 17"s which sucks but Im going with a 285/70/17 (33x11.5) Ive narrowed it down to a few ... Kelly TSR , Cooper Discovery Max, and Toyo OC at2s ... leaning toward the Coopers if I can find a good price on them I ran 3 sets of the Terra Grapplers on two f150s I owned had great luck with all 3 sets and got close to 50k but I rotated them every 3,500 miles .... Keep them from feathering and they last a while ... The only gripe I had was they sucked in mud but then again they werent mud TA's ...
