The Westlake ST100 is a durable trailer tire that features two steel belts and a nylon cap for high-speed stability. Not approved for use on passenger vehicles, the ST100's low-rolling-resistance rubber compound allows for better fuel efficiency and the tire's all-season tread pattern with four circumferential grooves boosts hydroplaning resistance by forcing water out of the tread.
