Description Roadboss RL503
The Roadboss RL503 commercial tire is recommended for installation on the steering and driving axles of high-capacity trucks. It is designed for use in medium and long-haul transportation. It is distinguished by its exceptional resistance to abrasive wear, fuel efficiency, quiet and smooth ride, and reliable traction properties on dry and wet surfaces.
The closed tread pattern consists of five solid longitudinal ribs. The central one and the edge elements have increased stiffness, which improves directional stability and handling accuracy at high speeds, reduces wear and the risk of cracks and tears in the tread. The remaining pair of ribs contains transverse lamellas, the edges of which provide stable deceleration on wet surfaces, preventing wheel locking at the same time. Another notable feature is the presence of wavy protrusions in the grooves. These elements prevent stones from getting stuck in the tread, pushing them out, thereby increasing the tire's passability on poor roads.
Key features of Roadboss RL503
- increased mileage due to an improved rubber compound with increased resistance to tears and abrasive wear;
- lamellas, narrow width of longitudinal grooves minimize noise, wear and rolling resistance;
- reinforced carcass, which is a four-layer all-steel cord, increases the tire's carrying capacity, prevents damage from excessive mechanical stress.
