The presence of 3D multi-wave sipes provides extra biting edges for improved performance in wet and snowy conditions. Thanks to the lateral grooves and stone ejectors, the Open Country A/T III resists hydroplaning by clearing water and debris, stones, and rocks from the tread to maintain consistent traction.
