Hello I'm new to the forum. Hope I put this in the right section.
I'm wanting to run Rockstar XD's on my 2007 dodge ram crew cab after i get a leveling kit installed. Im wanting to know what size tire i can run and if i will experience any fender rubbing.

Uuuugghh not the rock stars!!! Depends on whether or not you're a 4x4. If your a 4x4 make sure the rims you get have at least 12mm backspacing, or -4.5 offset. If the rim has that then you can fit up to a 12.5in wide tires. If its a 2wd I'd recommend just going by those same guidelines, but there is more room if it is a 2wd. And as far as height goes, you can fit up to a 35" tire but it will hit your fenders every time you bottom out. If you're just going to do a level I'd recommend 33"-34" tires. I hope this was of help to you.
