Hi All - I just replaced my tires on my JTR with Nitto Recon Grapplers sized at 37x11.5r17 on the factory Rubicon wheels. I chose to keep the wheels and go with 11.5 because I didn’t want much if any poke since I drive a lot of gravel/rocky roads. I expected some rubbing and wanted to see how much before deciding on a level kit or lift.

I am getting a little inner fender rubbing on the driver side when turned hard left after adjusting the steering stops. The rubbing is at the back, bottom of the fender liner.

I’m now wondering if the level or lift will be enough or if I need to look at either wheels with different back spacing or spacers. I would prefer to keep the tires as tucked as possible. Does anyone have experience with a similar combo or thoughts?

Thanks!

Probably going to run into those issues with or without the lift/level. I ran 37x12.5 on just a 2” level up front for awhile before going to a full lift with no rubbing. I’m on 17x8.5 -6 though, that’s the difference.

Are your front wheels centered in the wheel wells?

Even with taller tires, you're going to get a shift in the front axle. You may need an adjustable track bar to center things back up.

I'm running 12.5 37s on no lift. just a 1in spacer to get to +20 offset. works great. I'd recommend a lift for ya tho cus you can disconnect your swaybar and articulate much farther than me. 1in to 2in outta do it.

Right now, everything looks perfectly centered in the wheel wells.

I think that is where I‘m leaning now. Mostly concerned about if I also need to get a wheel spacer or different offset wheels.

I have a $3,000 out the door price for the Mopar lift. I like the idea of preserving the warranty, but really don’t trust the dealerships that are nearby to do the work. Leaning on taking it to a specialty shop, paying less, and forgoing the warranty. I think with the type of wheeling I do now, I can get by with an AEV 2” Spacer Lift.

3000 for a mopar lift is nuts. You can just buy some 2in springs from anywhere and the mopar LCAs separate and rock some bilstien for like 400 bucks if ya market place or forum source most of it. Shock surplus always has a deal on some 5100s or 5160s bilstien. and then you can pick up Mopar extended LCAs for like 60-70 bucks a piece from @AllMoparParts.com (you'll need 2) and then just forum or FBM some 100-150 2in lift springs local. you can easily even install that all yourself or take the bits to a shop. I recommend a rear driveshaft drop spacer for the rear if you lift higher than 1.5in and you can get that anywhere for cheap too.[/QUOTE]

I thought the same thing on the Mopar pricing!

Jeep Gladiator Lift/Spacer after 37x11.5r17 1714585166024-8u


37x12.50x17 with the same wheels you have. No lift. I had the same rubbing on the back of the front inner fender liner. I added two washers to the steering stops on each side and trimmed the liner a little. I don't have any rubbing now and even with 12.50 tires my "poke" is minimal. It can be done

what did you use to trim your fender liners? I might do that while I’m waiting to get the lift installed.

Good call on the trimming. Made a small cut and no more rubbing on road. I still need a lift for off-road but, this buys me some time.

I know there are a lot of threads on regearing, but at least non-highway, my Pedal Commander was able to compensate for the seat of the pants feel.

Hi All - I just replaced my tires on my JTR with Nitto Recon Grapplers sized at 37x11.5r17 on the factory Rubicon wheels. I chose to keep the wheels and go with 11.5 because I didn’t want much if any poke since I drive a lot of gravel/rocky roads. I expected some rubbing and wanted to see how much before deciding on a level kit or lift.

I am getting a little inner fender rubbing on the driver side when turned hard left after adjusting the steering stops. The rubbing is at the back, bottom of the fender liner.

I’m now wondering if the level or lift will be enough or if I need to look at either wheels with different back spacing or spacers. I would prefer to keep the tires as tucked as possible. Does anyone have experience with a similar combo or thoughts?

Thanks!

I used the 2 inch Mopar springs calibrated for a steel bumper. And put three-quarter inch spacers on the rear. I’m running 35s. But my jeep sits level and I bet 37s would fit under it.
