The Drive axle Sumitomo ST938SE tire is EPA SmartWay Verified because of its fuel-efficient construction. It features a new tread pattern that minimizes wear and delivers excellent traction. Its solid shoulder design works with rigid internal block configuration to reduce heel wear. In wet conditions, the deep, wide grooves remove water from the contact patch to improve hydroplaning resistance. The super deep tread delivers long mileage while microgrooves on the blocks reduce uneven wear and boost wet grip.
