Largest tires?

[Venompool]

Perhaps something covered I havent found yet. Can anyone tell me the largest tires I can run on a 2022 Ram 1500 Bighorn with a 2 inch motofab leveling kit on the stock 20x9 inch nite edition rims? I am hearing I can do 33x12.5, but want to make sure. Also not interested in rubbing or cutting anything for fitment.

Take truck to a good tire shop. They should be able to measure the relevant parts and tell you the largest tire that won't rub on sheet metal or steering gear. Rim offset plays a big part, whether you want the tires inboard of the wells is another factor, are you going to add flares etc. The 33x12.50 will be outside your fenders on stock Rims. Also, every truck is a tad different, especially after even a small lift. What works on one truck may not work on the same model if you are getting close to the limit.

I put LT285/65R20 BFG K02's on my truck and had zero rubbing with all stock suspension at stock height.

I then upgraded to all new B8 5100 Series Bilstein on all four corners and set the front to 2.1" raise, and no issues with this size of tire.

That tire is 34.5" tall x 11.2" wide. A full 1.3" narrower than what the OP is talking about. Doesn't mean it isn't good information, but as you well know, an extra inch of width can make a big difference in what rubs and doesn't.


1.3"

Thanks, from where I have been and seen..with the plus 18 offset the rim comes with it should be okay. But I will check a few other places as well

1.3"

Agreed!
That's what she said as well, and too bad I'm only my tire size, and not the 1.3" wider

You might also look at the Gallery at custom offsets. There may be some folks who have uploaded images and rub reports for various tires and backspacing combinations for your exact truck.
