The Discoverer STT PRO is built for overcoming obstacles and debris without sustaining damage, while providing exceptional grip on rugged terrains. It is constructed from a silica infused compound using Armor-Trek3 technology to prolong tread life and increase durability by reducing the likelihood of sidewall damage. The tires' raised rubber rib design helps eject stones from underneath, while its mud release dimples and alternating shoulder lugs get rid of loose soil in the tread pattern and increase mud traction. For an off-road tire, the Discoverer STT PRO delivers an astonishingly quiet and smooth ride. The experience can be credited to its hybrid inner tread rib pattern as well as flex grooves that reduce noise and dampen the impact.
