Unfortunately, with the onset of summer, we didn’t find much mud to test them in. The one small pit we got to had a depth of about three feet, and the Fierce Attitudes luckily found traction at the bottom of the sticky, muddy, clay loam—enough to pull it through the pit, both backwards and forwards. They did not clean out as well as we’d like, but that’s a tradeoff for a tire that drives better on the highway. The 315/75R16 Attitude M/Ts we tested had a 3,860-pound Load E range. The number is rather impressive for an aftermarket mud-terrain tire, and makes Fierce Attitude a good contender for HD work trucks or ranch trucks that need to haul stuff but also hit a lot of muddy roads.
