I got Wrangler M/T R 245/75 16's on the stock rims which is 5.5 backspace I think. Correct me if I am wrong anyone (tjkj2002) Guy's been schoolin my dumb butt lately. Really aggressive tread which may cause more rubbing problems. FYI: I also have a 3/8'' clevis lift up front and an extra iso pad in the rear. I may be a little higher than you.
I had rubbing at full lock on the fog lamp doors and air dam. The air dam was the worse. Sounded like a baseball card in a bike wheel times a hundred with a Mega phone. It was so loud when I would back up people a hundred feet away turned and looked to see what was making that noise!
Pinch weld was clear so I didn't have to pound that. I haven't noticed to much stuffing, yet, but I think I am going to get the N132L and extend bustops for the rear in the future and some extentions for the front.
I cut the air dam back and I used a heat gun to push the fog lamp doors forward. Some folks on here told me to put some aluminium foil behind the fog doors so you don't melt the wiring for the lights or your wind shield washer reseviour. I recoomend you do so. Better safe than sorry!
I'll include some links with pics of the tire.
