Largest tires on Stock Rebel suspension and wheels

[KOOPS]

Yes. I put a 35. You're good.

Great, thanks for confirming. I wanted to buy a full size 285/75/18 spare.

Ok so my first post here and I know everyone is tired of tire posts.

I have a 2021 Ram 1500 bighorn with factory 18's. Not a rebel. Everything I'm seeing on Reddit seems to point to 285/75/18 should work for my truck as well. Is that correct? Truck is completely stock. Just hit 46000 miles and I'm due for tires and want to get something larger like everyone else. I'm not wanting to do a leveling kit at the moment but maybe somewhere down the line. I just want a pretty reinforced answer. A lot of rebel talk on the interwebs and 20" rims but couldn't find a definite for what I've got. Thanks
