Getting new tires for my 22 X3 Max that's on its way. I live in Iowa and drive hard surface and dirt/gravel mostly. Will take out west on trips as well. I really like the BFG KM3. Was thinking that I would go to 32". My buggy is a Max DS Turbo RR. I'm reading that if I went to the 14" BFG in a 32" that I would have rubbing, so if I'm changing to wheels, I may as well go to a beadlock and go to 15". What offset should i run with my setup?
