Supermax Stm-1. FEATURES AND BENEFITS: Trailer tire, NOT FOR LIGHT TRUCKS; Improved controllability; Enhanced durability; . OVERVIEW: The Supermax Stm-1 is a highway terrain, all season tire manufactured for trailers. This tire is NOT MEANT TO BE MOUNTED ON LIGHT TRUCKS, as its construction will not support the weight and performing style of such vehicles. It can ONLY BE MOUNTED ON TRAILERS.The tire is easily controlled in all weather. The symmetric tread design's ribbed pattern closely follows the road surface at all times, which enhances the steering responsiveness and the driving stability. This improves the steering response time and accuracy to the driver's commands, while also stabilizing the tire's structure against the driving pressure affecting the model. The optimal shoulder tread pattern increases the cornering capability as well. It increases the number of biting edges to ensure a secure towing experience.The tread pattern and the all season compound work together to increase the all weather traction. The tread design's symmetric ribbed pattern with the optimal notches and circumferential grooves firmly grips the road surface in dry, wet and winter weather. The all season compound keeps its rubber flexibility and guarantees traction throughout the year, from the heat of summer to colder winter weather. The circumferential grooves also manage to prevent hydroplaning. They disperse water and slush from below the tire's footprint and enhance the wet and winter weather traction.The Stm-1 provides a durable performance. The reinforced full nylon construction increases the tire's load and driving durability. It maintains the optimal tire shape and prevents its deformation during the drive. In this manner, it increases the tire's load carrying capability as it maintains its optimal shape under the load pressure affecting it. The optimal tire shape also improves the model's performance and it makes the trailer easier to tow in all conditions. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
