I was running the ready lift 2.25" and it was rubbing on the inner fender basically where the fender liner bolts to the bottom of the fender. I probably could have trimmed a few things but I really didn't want to cut up a new truck. My other option was to put the zone 1.5" body lift on but the shop that I go to doesn't care to do them and charges a little more for the labor, lol. I know every truck is different but I just thought I would share my experience with you. By the way the Toyo R/T's are great tires. Hardly any road noise and they look great.
