Zeemax TrailExpress II. FEATURES AND BENEFITS: All season traction; Enhanced controllability; Increased load capacity; . OVERVIEW: The Zeemax TrailExpress II 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 also enhances its all season traction. The all season compound works with the ribbed tread design to significantly increase the tire's year-round performance. The better flexibility of the compound throughout the year, optimizing its summer and winter weather applications. The tread elements provide additional biting edges, enhancing the tire's traction during its performance. The footprint also features four circumferential grooves that disperse water and slush. As a result, hydroplaning resistance if effectively boosted as well.The tread's symmetric ribbed pattern guarantees consistent surface contact. In this manner, the tire is able to effectively enhance its controllability. This promotes faster and more precise steering responses to the towing vehicle's commands. Additionally, the surface contact also improves structural stability, which also prevents trailer swaying. The ideal shoulder block placement increases cornering by providing additional biting edges. The combination of these improvements upgrades the tire's controllability and maneuvering.The TrailExpress II features a reinforced internal structure. This construction does not allow the tire to deform under load and driving pressure. In this manner, the tire is able to effectively enhance its overall load capacity. Since the tire maintains its ideal tire shape, significantly improves its overall load capacity. 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.
