2019 Laramie longhorn tire size upgrade

[Paulm235]

Hi everyone, I know this is a heavily posted topic but didn’t see anything relating to my particular vehicle. I’d like to know what is the max tire size I could put on my stock 20 inch rims. It hasn’t been lifted or leveled, it’s all stock.
Thanks

Rim size is irrelevant, the diameter of the tire and the height of the side walls are the deciding factor. You can buy a 33 or 35 in a 18 through 22 inch wheel.
So yes you question has been answered before, search stock truck.
