Westlake ST100 Tires

Trailer - Radial

Westlake ST100 is an all-season trailer tire made with long-lasting tread and compounds that promote fuel efficiency. Thanks to the double steel belts and full nylon cap, ST100 maintains its shape at heavy loads, improving its strength and durability. This construction ensures that the tire provides excellent performance at high speeds while fully loaded. The long life of the tire also promotes reduced rolling resistance, which makes it fuel-efficient and environmentally friendly by minimizing CO2 emissions. As an all-season tire, it features four circumferential grooves that help to evacuate water and slush away from the tire’s footprint, and reduce the risk of hydroplaning in challenging weather conditions.
