Royal Black SL101 235/75 R17,5 143/141L

Royal Black SL101 — a strategic solution from a trusted manufacturer in China, challenging stereotypes about the budget segment. This is not a simplified model, but an optimized platform for heavy commercial vehicles.

Stability for the steering axle

The basis of the tire is a balanced tread design with five ring ribs formed by medium-sized blocks. The key feature is a system of internal bridge stiffness integrated into the block structure. These elements prevent excessive transverse displacement in the contact patch under high torque. The result is the preservation of optimal contact geometry during acceleration and maneuvering, which directly increases the coefficient of friction, reduces uneven wear (bulging, "teeth") and provides predictable handling on any surface.

Self-cleaning and all-weather drainage

The developed network of wide channels performs two key functions: it provides rapid evacuation of water masses, reducing the likelihood of aquaplaning, and promotes effective removal of dirt and small solid particles. It keeps the tread in a clean, "open" state, guaranteeing that the pattern retains its gripping and drainage properties in real road conditions.

Adaptability to temperature challenges

A modified all-season compound has been applied here, designed for a wide range of temperatures. Its formula ensures the preservation of optimal elasticity, both in summer heat, preventing overheating and increased wear, and at near-zero and negative temperatures, maintaining grip on cold and wet asphalt. This makes the model a universal solution for regions with a moderate climate and inter-seasonal operation.

Main features of Royal Black SL101:

- block stabilization system minimizes tread deformation for improved traction, handling and even wear;
- wide, optimized channels for effective water, dirt and self-cleaning of the tread;
- universal all-season compound maintains working characteristics in a range of different temperatures, providing flexibility and traction;
- robust carcass construction is designed for multiple overloads within permitted limits, ensuring high potential mileage.
