Well my TOYO 35's rub on the front, I had to put on a 2" lev kit. I am going with 315's when the 35's go bald and I will take off the 135. 00 cost 2" lev kit. I had to take off the mud flap on the front with the 2" lev kit and the 35's and they still rub on a tight turn and hit a bump. So still with the 2" lev kit and 35x12. 50x17 on American Eagle 9" x 17" rims, still hit a little, just don't go hitting a bump on tight turns and everything is ok. did this help? Everything else is stock on my truck, ok I have the 6. 7 eng, is that more on the front?
