Delta Sentinel UN33 Overview


The Sentinel UN33 passenger tire from Delta is engineered to provide improved braking and driving even in wet conditions. Rated for all seasons, the asymmetric grooves increase handling for wet weather reliability. Angled treads keep water away from the tread path, improving traction. Specially designed treads increase braking for accident prevention. Variable tread blocks help reduce road noise for a quieter ride. The Sentinel UN33 also features a unique rounded shoulder that enhances turning as well as reducing wear for longer performance.
