Arisun AD778. FEATURES AND BENEFITS: All weather traction; Enhanced controllability; Upgraded load durability; . OVERVIEW: The Arisun AD778 is a highway terrain, all season tire manufactured for commercial vehicles. It was made to be mounted on the vehicle's drive axle.The ideal tread design and the all season compound improve the tread life. The symmetric ribbed tread design enhances the surface contact during the drive. This allows the tire to evenly distribute the driving pressure along the tread area. The equally spread out forces of acceleration, cornering and braking avoids irregular wear formations across the tire's footprint. The stronger compound keeps the rubber flexibility and prevents heat buildup which regulates the tread wear rate, avoiding premature wear. This combination increases the usability and service life.The tire upgrades the controllability by utilizing the tread design. The symmetric tread design features an optimized block placement and a zigzag, wide center rib, which manage to increase the surface contact throughout the drive. In this manner, the tire upgrades its steering responsiveness and the driving stability. The steering becomes faster and more precise in its response to the steering axle's commands, while the structure is secured against the driving pressure affecting the model. As a result, the tire enables the driver to confidently control the entire vehicle at all times.The AD778 upgrades the load durability. The tire features a stronger internal structure which maintains the ideal tire shape under the load and driving pressure affecting the model. This guarantees the tire's strengthened load capacity during the drive. The reinforced construction does not allow the tire to deform under the pressure affecting the model, which enables the tire to carry and withstand heavy loads with ease. This allows the tire to improve the heavy-duty driving safety levels. 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.
