Spare Tire Rubbing Bumper

[Benny67]

I put 275/70/18 on my 2021 4 door sport altitude JL on my stock 18" wheels. It now rubs on my bumper. What do you guys recommend ? Leave it or relocate it ideas ?

Maybe the factory bolts were a hair loose?
I say loosen em up, angle it back to a suitable position and torque it back down.
If you need a vid there’s the TeraFlex vids online on how to get everything taken apart

So many options.
-New bumper that allows for larger tires.
-Going bumper less - I did this for a couple of months until my new bumper came in.
-upgrade to a heavy duty tire carrier - best in my opinion for larger tires.
-I'm running Rusty's off-road rear stubby bumper 35x12.5 MT. The tub armor is a separate order.
-I believe there is a kit that allows you to run larger tire. If I remember correctly it adds something to the stock unit. - cheapest option.
Just kind of depends where your heading with your Jeep. I want to end up at 38" or a 39" but that's a ways down the road. Hope this helps.

Teraflex spare relocation bracket kit. Aluminum brackets that weigh maybe a couple pounds, comes with tailgate bumper spacer kit , very simple install, accommodates up to 37” tire yet only raises tire 2”, no sensor issues. Highly recommended. The ~13lb RC relocation plate I bought first is in the garage. ? ~$135–$150 source dependent.

The only real proper solution, that doesn't fix one problem while adding another, is an adjustable carrier. If sticking to 35's or smaller, I highly recommend the Teraflex Alpha HD carrier.

The Alpha has 3 height positions to properly clear the rear bumper. This is important, because the bumper is hard mounted to the frame, whereas the body is mounted to the frame via rubber isolators. This gives the body and bumper the potential of being able to move independently from each other. If the spare is contacting the bumper, that independent movement will transfer unnecessary stress to the tailgate.

The Alpha has a horizontal slide adjustment to account for a broad range of wheel and tire dimensions. Being able to keep the spare as close to the tailgate is important. First off, it minimizes the cantilever affect. The more a given weight is cantilevered, the more amplified its stress forces will become. Secondly, having the inner sidewall of the spare pressed firmly into the rubber tailgate bumpers will minimize rattles and shakes. Those unwanted movements could possibly be damaging over time, or at least drive you nuts from hearing that racket caused by every crack in the road.

Here's a pic of the Alpha carrying a 315/70-17 bfgoodrich ko2 and set to the highest position...

My 35x11.5x17’s rubs the rear bumper slightly. Once the tire gets rotated in and gets some wear, it will no longer rub the bumper. I’m not worried about it at all.

I just picked one of those up from Amazon, and started installing it today. Based on the instructions, it said I could use the middle position for 35's with the stock plastic rear bumper, so that's where I set it...was hoping to not have to pull the studs and relocate them to the top holes if I someday upgrade to 35s (currently running 285/70 KO2s).

Oh yeah, I should've mentioned that I used the highest position because I wanted to maximize drop-off clearance. Your right though, the middle position is best for bumper clearance and maximum view through the back window with 35's.

Awesome, thanks for the info!

Figured I'd bring this thread back, because I finished the install over the weekend. Here's the Teraflex Alpha carrier with the studs set to the middle position and a 285/70 KO2 tire. Plenty of clearance at the bumper now; before, it was actually resting on the bumper with the stock Sport tire carrier. This carrier is awesome, and the view out the window is actually better than before since it gets rid of the plastic bracket that the brake light sits on.
