I have a 2021 overland with a level lift and stock overland wheels on it if I were to put 33x12.5 R18 AT tires on it will itfitwith no rubbingorwould I need new wheels or wheel spacers.
I have a 2020 overland with level kit and I went with 285/70 18 (essentially a 34 X 11.50) on an 18 X 8" wheel. Fits perfectly! no rubbing. Its very close though, I imagine 12.5 might rub.
If you are keen on new wheels go that route and switch to 17s.
Some tire installers may have issues installing a 7.5" wheel on a 12.5" wide tire. I think some of the sites said the wheel needed to be 8" or more wider for that tire?
I had a set of 37x12.5 tires installed on my OEM Overland wheels by Discount Tire without a problem but am using spacers and am on a 2" Mopar
I initially grabbed a set of brand new Mojave take offs and looked and fit great with only a 3/4 spacer lift front and rear. Maybe look into that route, it will probably be cheaper than buying a set of new tires anyways. Unless you’re dead set on keeping your stock wheels.
