Largest tire size on 18" rim

[asalowe3]

I have a 2019 Ram 2500 Big Horn that came stock with 275/70R18 tires. The truck is stock and does not have a leveling kit or any aftermarket suspension. I'm looking to go to an AT tire and wondering if I can fit a 295/70R18. Any thoughts?

Also following. Looking to go from the 3640# rating on the stock 275/70 18s to the 4080# rating on the same tire in 295/70 18. If folks aren't having luck with those, I'm also looking at going to 19.5" wheel & tire combo for the rears.

That's a 34.5 x 11.5 inch tire. There are already a lot of threads in here on the largest tire sizes you can use on various offsets. If you're not sure of the overall size of the tire, use one of the online size calculators, like this one. https://tiresize.com/calculator/

I run 285/75-18s on mine. They fit fine with no level no lift.

I have a 2020 2500 no lift and no level mine came with 285/60/20, I just put on 295/65/20 they are about 34.5 tall. No rubbing lock to lock forward and reverse.

I'm back and forth about tire size. This is the closest thing I've found to a straight answer.

Just put Hankook Dynapro AT2s on 325/65r18. Look nice and mean now. Turns lock to lock no problem. They are sitting on +12 offset.

Those wheels are 18x9.5, correct?

 

[Squatch]

Yeah 18x9.5 with +12 offset. Tires workout to being 34.6 tall by 12.9 wide. So stoked about them. They look great. They are no louder than the stock tires they replaced, quite a bit better ride. I’m running them at 50 PSI all around, but will pump the rears up to 60 when towing.

I put 35×12.5 on my stock 18" rims. No issues at all. No lift, no level either.

I have a stock 2019 Laramie 3500 and I fitted 295/70R18 Bridgestone DUELER A/T REVO 3 on my stock rims and have had no problems with them. It makes the speedometer 1 mph slower at 60 mph.
