does anyone have problems with tire rubbing with bigger tires?

I have 33x12.50 with a 6 inch lift

 

No problem. I don't have any lift other than the little bit extra body lift on the Off-Road 4x4 package, so with a 6" lift, you should have absolutely no problems. I just got some ProComp 33/12.5R17's on mine. I had a little bit of rubbing on the front fenders. It was on the lower portion of the vailance fender (plastic anyways). I just shaved the plastic off, but you can't tell at all. You probably could fit 35"s without any worries. Good luck!

 

I've got 7" of lift and I am running 35's with no rubbing at all. I'm thinking of going to 37's when these start to wear.
