Roundrule ST Radial
OVERVIEW
The Roundrule ST Radial 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 promotes exceptional year-round performance, by combining the all season compound and the detailed ribbed block placement. Their combination helps to enhance the tire’s performance in dry, wet, and winter conditions. Stronger rubber materials keep the tire pliable throughout the year, optimizing its summer and winter grip. Additionally, the tread generates biting edges in order to increase its grip on the road surface. Circumferential grooves also effectively prevent hydroplaning in wet conditions.
The stable ribbed block placement maintains surface contact while the tires are in motion. As a result, the tire manages to effectively upgrade its steering responsiveness and driving stability. Closely following the road helps the tire enhance its steering responses and accuracy to the driver’s commands. It also actively improves its structural stability, avoiding trailer swaying in this manner. These elements allow the tire to boost towing safety, increasing the towing vehicle’s control over the trailer.
The ST Radial uses a strengthened radial construction to improve load durability. The durable casing maintains the ideal tire shape under load and driving pressure, improving its overall load durability. This promoted better load capacity, ensuring the tire’s overall load-carrying capability and promoting a secure performance.
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.
