Mud Terrain tires offer drivers traction on off-road terrains such as mud, dirt, sand, gravel, and rock, and are commonly used on CUVs, SUVs, light trucks, and jeeps.

Designed for use on light trucks and SUVs such as the Ram 1500, Ford F-150, and Chevrolet Silverado. Light Truck tires are strong enough to support a truck's heavier weight and whatever else is being hauled or towed.
