I'm getting ready to pull the trigger on 6 new tires for my 3800 dually (now is a time when duallys aren's so cool). M.E.Miller Tire in Ohio has the same STA tire as Coker or Universal, but they're $30 cheaper per tire. Coker and Universal had no good explanation and weren't interested in price matching. Am I missing something? Does Miller have a good reputation? Anyone have any experience with these guys?
