And ask the question.... what size?

But I'd like to preface the question by saying that all the searches I've done I can't say I have come up with a definitive answer since everyone has so many variables going on and everyone has a different answer so hopefully posting here might help me.

I have a (4th gen) 2021 Ram 1500 classic Express night edition crew cab 4x4 with the 20-in midnight Edition rims.

I would like to know, without a level kit or any suspension work whatsoever, what is the biggest tire I can fit on these rims. I'm hoping someone out there has the same setup with no modifications whatsoever and can possibly give me a good answer.

No aftermarket rims, no spacers, no leveling kit etc.... Bone stock.

Thanks and sorry to be that guy posting the age-old question lol

[emoji23] I'm running a 33 12.5 r20 with swaybar rub at fill Lock. I'm Sure any bigger is a level or wheels.

Fenders look filled but not stuffed. Theres a couple thousand pounds of wood in the box.

I know 285/65-20 usually rubs a little at lock over bumps. 275/65-20 fits 95% of the time no issue (that's what I'm running) not sure on the wider/lower profile options. 275/65-20 is a 34" diameter tire.

LT 275/65R20. Like stated above 34" tire and it does not rub. My truck has stock suspension up front.

Looks good, and thinking of doing the same
Did you do any updates for your speedometer or odometer?

^^^ Yes I have a Procal and adjusted for my tire size.

+1 on the 275/65R20. No rubbing at all stock but looks even better with a 2 inch Bilstein front end lift.

Nothing I ever own stays stock, that's too boring for this guy

This is probably the route I'll be going as I still need to fit in my underground
