I know the attributes for bias/radial, but how not the actual extent. The greater rolling resistance of a bias ply will reduce mileage (as in MPG), but how much? On a comparable tire (like a TSL bias and TSL radial) what kind of mileage (as in life of tire) could I expect? I'd like a tire that I can get some mileage out of and has stronger sidewalls than a BFG or Procomp (tired of replacing the things). I'm looking at Ground Hawgs and Gumbo Mudders because I heard that they wear longer than a TSL, and have pretty durable sidewalls. Anyone know what kind of life a 36-14.50 TSL radial will get compared to a 35-14 bias Hawg? That being said, I'd kind of like to stick with a radial, it is my daily driver after all. How much stronger are the TSL radial sidewalls compared to BFG's?
