An all-terrain tire, the Cooper Discoverer RTX2 is designed for use on light trucks and SUVs and features alternating shoulders that enhance traction in mud and soil. Wide-base lugs force rocks, stones, and other debris out of the tread for consistent traction and to protect the casing from damage, and the Discoverer RTX2's sawtooth grooves bite into icy, slushy, and snowy roads for better winter traction and grip.
