I have a 2019 Ram bighorn with 2” Mopar lift and ORG front springs. I’m running the stock Rebel wheel/tire right now but I’m wondering if I can fit a 33x12.5 on the factory Rebel 18” wheels with my setup with no rubbing/trimming. Leaning towards the BFG KO2’s if it will work.

You mean 35"? As the current Rebel OE tire is already 33". Assuming you are asking about 35" I'm curious on this also. Guessing it should be ok but wonder if anyone has run those KO2s. Obviously the 12.5" would be different too.

I am actually sticking with the 33” diameter to conserve what’s left of my gas mileage. I just want a little wider stance with the 12.5” wide BFG’s rather than the 11” wide oem goodyears

I am curious If I would be able to fit the 33x12.5x22 BFG K02's on the stock 22" Laramie Sport wheels with the non ORG coil spring suspension and OEM mud flaps.
The OEM goodyears are a 32.1" OD with a 11.2" section width. The BFG's are actually a 32.5" OD and 12.5" section width on a 10" wide wheel. With the stock wheels being narrower would that decrease the section width a bit. So I think i am looking at less than 1/2 an inch of an increase in OD and 1"-1.25" in width. Would I need a level or to do some trimming for that or will they fit? Has anyone tried it?

The 33x12.50x18 K02's are listed as a 8.5" minimum width, are the OEM wheels really 8"?
You may need to get a wider wheel if that is the case or you could look at something like a 285/65R18 that will work on a 8" wheel.

I’m pretty sure the rebel wheel is 9in wide. I can’t remember if it was here or not but I did read somewhere a 12.5in wide tire will fit a 9in wheel

No, the rebel wheels are 8” wide. The OEM 20” wheels are 9” wide

Hey guys,
Old thread but came up when searching for fitment of 33x12.5 R18 on a rebel with 18's and air suspension.

No real answers in my search but decided to take the risk and just installed 33x12.5 R18 Yokohama Geolandar M/T on my stock rebel with air suspension.

Fits good on all modes with no rubbing, sidewall is about 1/2 - 1/4" from the UCA and doesn't touch. Tires are surprisingly tame and quiet given the thread pattern and over all happy with the outcome.

Would love to see a picture from the front

Nice. I'd like to see some other angles too. I was afraid they would rub UCA's.

Hey guys,
For those asking for more pics, attaching a few. Also it may not be clear but the tires do not poke out of the fender flare.

I have 275/60r20's with a 2in level right now (no ORP or air ride). Would 33x12.5r20's fit without rubbing the control arms, or would I need spacers?
