Best way to fix tire rub.

Hey guys. I went from 275/70/18 to 285/60/20 with a 2 inch leveling kit and a -25 offset so I can pick up almost .75” of clearance from UCA. My issue is that tight turning I am rubbing by at most .50”. Can’t cut the plastics as metal and bumper are there. One suggestion was to tap the bottom of the bumper and pull the plastics in tighter, and reattaching with the body pin. Other suggestion was to go from a 2 inch leveling shim to a 2 1/2 or 3 inch in front. I am not at all mechanically savvy. I am trying the best and most economical way of doing it.

 

@Coachbuilder1 makes bumper shim kit, plastic inner fender wells can be treated with heat gun and small 2x2 wood and reverse clamps to push back or re mold the plastic. CMC for cab mount. Theres several threads on this subject

 

Forgive my lack of technical knowledge, what’s the bumper shim kit for and what does it do?

 

moves front bumper forward by 1/4" (when you install one shim on each of the 2 front bumper mounts) or by 1/2" (when you install two shims on each bumper mount)

this kit is what inquiringone referenced above, and what i have installed. kit comes w/ FOUR 1/4" shims; i installed TWO on each mount for a total of 1/2".

your OP sounds like your rubbing front bumper plastics. these could help w/ that.

 

thank you for the help. Is this fairly easy to install? Just remove bumper, shim and replace? Do you have to worry about any parking sensors?

 

If you have a platform to set the bumper on, you shouldn’t have to move it away from the truck. It’s 4 bolts on each side. Just slide it back far enough to put the shims in and bolt it back up. If you can do it that way, you wouldn’t have to unhook the sensors. When I replaced my bumper, I just put enough old wood and pallets under it to hold up the new one and slide it on.

 

i loosened the nuts (believe there was four per mount) on each mount, almost to the point of removal. slid the bumper out. then removed the nuts from one side, and slid each shim, one at a time over the bolts, put bumper in place and added the nuts back (just enough threads to hold).

then i moved to the other side, removed those nuts and slid each shim in, one at a time. put bumper back in place and added nuts back.

secure all nuts and double check.

i did not have to remove any sensors or the bumper. just do one side at a time.

 

Thanks all, I got the shim kit arriving Monday, just got a heat gun to bend the plastics. I crawled under the truck and wear the rub occurs in the rear is a meeting of two body panels on a 90 degree, I’m gonna bend those flanges back behind themselves, mold the plastic, and that should give me the about 1/4 inch I need to stop rear wheel rub on a tight turn.
