Tianfu RD-103. FEATURES AND BENEFITS: All season traction; Enhanced controllability; Upgraded load durability; . OVERVIEW: The Tianfu RD-103 is a highway terrain, all season tire manufactured for commercial vans.The model offers great all season traction thanks to the tread design and year-round compound. As a result, the tire is able to significantly increase its dry, wet, and winter weather performance. Durable rubber materials allow the tire to optimize its rubber flexibility, enabling its summer and winter grip. The groove pattern and the ideal block placement firmly grip the road with extra biting edges. Circumferential and angled lateral grooves prevent hydroplaning by dispersing water and slush from the footprint in wet conditions.Better handling is also guaranteed with the ideal footprint. It features a continuous center rib and optimally placed solid blocks that ensure the tire's surface contact. Their combination provides the necessary traction and road contact significantly improves handling and maneuvering. The solid center rib provides better steering responsiveness and driving stability, while it also secures structural stability. The shoulder block pattern provides a higher number of biting edges, upgrading cornering and maneuvering.The RD-103 also improves excellent durability. The reinforced internal structure maintains the ideal tire shape under load and driving pressure. As the tire does not deform under load pressure, increasing load carrying and withstanding power. Additionally, the stable footprint and durable compound also enable the tire to enhance its usability. They prevent tread scuffing, which is prominent in commercial applications. Its ideal tread design, tread damage resistance, and stronger load durability enable the tire's exceptional performance. There might be discrepancies of sizes between brands and models of tires which have this size formatting. As the manufacturers only provide the tire width and the rim diameter with these tires, various brands and models will have size differences. In order to ensure the correct size is purchased, the overall tire diameter that is needed should be checked.The Overall Diameter or O.D. advertised represents the tire's overall diameter in inches, once the tire has been properly inflated and mounted per the manufacturer's recommendation. This advertised number is provided to Priority Tire by the tire manufacturer. 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.
