What size BFG KO2 can I fit on stock 18in wheel

[cdautrey]

I have a 2019 Ram 1500 bighorn 4x4 with the sports package. I want to put a 2in rough country leveling kit on it. But I’m tryin to figure out how big of tire I can put under it. I’m going with BFG KO2 tires Some one answered answered and said 33 x 12.5. I have a 18 in wheel i forgot to mention that. Can I fit 34 x 12.5 R18? recommendations? Was also told i could do a 295/60/18

I have not done what you are asking about, but I know the tires will fit the wheels with no problem. If memory serves me correctly the factory 18 inch wheels are 8 inches wide. The 12.50 tires are generally recommended for 8-10 inch wide rims.

There are guys running 35's with a 2 inch level with the correct offset wheel. I think most are running a 0 offset. The factory wheels are a positive offset ( I believe +19) so the rim sets inward versus a negative offset which sets the wheel further toward the outside of the wheel well. I would think if you run into problems it will be the tire rubbing the frame/ inside of the wheel well at full turn. I would think 33's would be fine. 35's would probably rub at full turn. I think some have run a wheel spacer to set the wheel out a little wider which will help.
