So I'm buying new rims and tires. I have an 06 2500hd and running 285 75 r 16 right now. I wanna get something wider and a little taller. I ve decided on getting xd badlands chrome 18 X 9 with 18 mm offset. I do like the looks of toyo open country Mt. I don't want to put a lift on so I was wondering how big I can go with out doing g to much to my truck. I already have the front valance notched. Anyone running something like that. I really don't wanna go anything bigger that a 35 x 12.5.
