Description

The Greenball Towmaster STR (Special Trailer Radial) is a highway-terrain, all-season tire specifically engineered for trailers. Recognized as one of America’s most trusted trailer tires, it is designed to provide high-speed stability and long-distance durability for a wide variety of hauling needs. Built with a dual steel belt construction and a reinforced belt-edge package, the Towmaster STR focuses on reducing trailer sway and providing a smooth, controlled towing experience. Its specialized tread compound is formulated for low rolling resistance, which helps improve the fuel efficiency of the towing vehicle while ensuring even wear over time.
