Tire size help.

[RamHemi2500]

Hello all. I have a set of 20x9 fuel coupler rims with a +1 offset in my 2015 Ram 1500 crew cab. I put the stick tires on which are P275/60r20. I want to get the Nitti Terra grappler G2. And would like to go a size or two higher and wider. I would like to know what size that would be and if it would fit without doing any mods. Thank you. New to this.

You'll be able to run 285/60/20's on that setup no problem.

If you want a larger diameter tire, you'll want a larger aspect ratio (width/aspectratio/diameter)
