Hi,
Im hoping someone could help. I would like to put on BF Goodrich KO2's tires on a stock 2020 Big Horn 4x4. I really do not want to level it and was just hoping to put on the biggest tire I could. If anyone could give me their input on what works and was does not. Any input and pictures would be greatly appreciated.

275/65/20 fill the wheel well up nicely and are about 10.8” wide vs the 11.2” wide on the factory tires

Also the 275/65 will be a lot more affordable

Thank you so much for your response. I'm just worried about rubbing. In your experiences do you know if either the 275/65R20 or the 285/60R20 would rub. I really hope to get the size that looks the best on the truck. Thank for your time and any additional input.

285/60/20 is the factory tires size and will not rub

275/65/20 will not rub and is a little bigger but slightly more narrow. I haven’t seen these on aftermarket wheels. They look fantastic in my opinion and in some cases are cheaper.

Thank you so much! Im keeping the factory rims, I didn't see 285/60R20 as a factory size but knowing now it makes me feel better.

That’s my fault.

I was under the impression we were discussing Ram HDs.

My apologies. I could be completely wrong now lol. Sorry for the confusion.

That said I believe you’ll be able to fit a 285 under your truck. It’s essentially a 33” tire.

Call up discount tire and they should be able to help you out. Also they do test fits.

With my Ram 1500 I wouldn’t put a 275 on as I believe they wouldn’t fit ona stock height and stock wheel.

Running 285/65r20 tires on OEM 20” wheels and 2” lift kit

My question is straight to the point: Anyone running 285/65r20 tires on OEM 20” wheels and 2” lift kit? If you are please, post pictures and state if you used spacers and if there’s and rubbing or scrubbing. Thank you.

If you are running stock height; then I would recommend a 33" tire 275/60R20 or 285/60R20. Based upon the thousands of tire size posts I have read, a 33" will fit nicely on a stock setup. a 275/65R20 or 285/65R20 will be 34" and will likely give you some rub (not to mention very little clearance for suspension articulation). Midnight1988's truck looks AWESOME with the KO2 285/65R20 tires; but I think that may be a little big for stock suspension. Stock tire size on your truck should be 275/55R20; which is about 32 inches tall and 11 inches wide.

Thank you for your time and input. I think Im going to go with the 285/60R20 BFG KO'2s. Do you think with the slightly extra width I would be ok? Greatly appreciated!!!!

Your front tires may rub slightly on the plastic wheel well liner on a full lock turn (especially in reverse). Some forum members have used a zip tie on the liner to eliminate any rub.

Thank you so much for your prompt replies and info.

I’m running 275/65/20 on a wheel that is 1mm offset more than the stock wheels and I had no rubbing before I installed the leveling kit. I think the 33’s look too small on these trucks, the 4th gen models came with 33’s I don’t know why they went to 32’s on the 5th gens.

Thanks for the compliment.

I agree with you 32's are way to small, thanks for the input.

I know this is an old thread but I’ll just post here anyways. I did a 2” level and now I just installed 285/60r20 KO2s on +18 20x9 rims and they fit perfectly. At full lock there is still a half inch of room so I could see the 295/60r20s also fitting but I didn’t want to go that wide. Although, I apparently have an extra inch of lift all around from a rebel level 2 pack. My truck is a sport (Canadian market only) but has this rebel option.
