I just got off the phone with my tire guy. I was buying a set of bfg mud terrain 315/75r16 for my 85 chevy 3/4 ton 4x4. He calls back and says they are backordered over a 1000 sets and it will be at least a month before they come in. He talked me into Pro Comp mud terrain on mickey thompson 16x10 classic 2 rims. Are the Pro Comps any good? I still have time to change my mind. I just want to make sure they are good tires for mud, highway, sand, and rock. I'd like to get at least 40,000 out of them. Thanks for the help.
