The Goodyear MT/R is the final step in trail traction. This aggressive tread is computer-designed to be quieter than the old MT; it’s still loud in comparison to the other Goodyear light-truck radials. This tire can be expected to provide good traction in all conditions but ice. In deep mud the tread clears itself quickly when spun-up. The sidewall is equipped with what Goodyear calls Durawall technology, which involves use of three sidewall plys and a silica compound for increased puncture resistance in the rocks.
