Royal Black SL007 385/55 R22,5 160K 3PMSF

The Royal Black SL007 commercial tire is designed for installation on trailer axles of highway trucks, which are mainly operated on high-speed highways and roads with solid surfaces. The model is focused on long-distance driving under constant load and combines directional stability, fuel efficiency, and increased resource during intensive operation in long-distance transportation.

The tread pattern is made in a closed design with enlarged shoulder areas, characteristic of tires in this segment. In combination with the optimized tread profile, this increases the contact patch, stabilizing its shape and size during movement, increasing traction and reducing wear and rolling resistance. Wide longitudinal grooves effectively drain water from the contact area with the road, improving stability on wet asphalt and reducing the likelihood of aquaplaning when driving at high speeds.

An important feature is the composition of the tread rubber compound. The compound is selected with a focus on "highway" operation: it is resistant to abrasive wear, increasing the tire's mileage and maintaining stable characteristics over a long period. This allows reducing operating costs when using the tire on trailer equipment with high annual mileage.

The carcass is designed for prolonged operation under high static and dynamic loads. The reinforced all-steel multi-layer structure provides uniform pressure distribution across the contact patch, increases resistance to deformation, and helps maintain the tread shape. Such a carcass architecture has a positive effect on the tire's mileage and reliability during operation as part of highway trucks.

Key features of Royal Black SL007:

- optimization for trailer axles provides stable behavior and low rolling resistance during highway transportation;
- rigid shoulder ribs improve directional stability and reduce uneven tread wear;
- wear-resistant compound increases the tire's resource during long-distance driving.
