The Sentury Qirin 990 tire is designed for use in dynamic versions of passenger cars. As an Ultra High Performance model, it demonstrates its inherent features — accuracy of handling and stability of traction at high speeds, increased efficiency when braking on wet pavement.
To a significant extent, the combination of such driving qualities is ensured by the asymmetric tread pattern. It is a combination of three solid longitudinal ribs in the central part and enlarged shoulder zones. This configuration provides a balanced distribution of loads and precise manageability even at high speeds. The central part contributes to stability on a straight line, and the outer part of the tread with large blocks increases traction when maneuvering. Most of the water-removing grooves are also located there, which effectively remove moisture, minimizing the risk of hydroplaning.
The tread pattern implements a technology that provides different stiffness of the tread zones depending on the functions performed — traction, drainage, and stabilizing. This allows for confident traction on wet and dry pavement while maintaining a high level of comfort. Another feature is the system of element arrangement, which reduces noise due to the optimal alternation of blocks and reduces vibrations during rolling.
In the manufacture of the tire's rubber compound, a combination of high-quality synthetic polymers, silica, and natural rubber is used. This formula increases the elasticity and heat resistance of the tread, improving traction at different temperatures and reducing rolling resistance. The increased silica content provides confident behavior on wet asphalt and at the same time contributes to fuel savings.
Main features of Sentury Qirin 990:
- asymmetric tread pattern provides stability and accuracy of handling in any weather conditions;
- reinforced breaker and cord construction guarantees strength and stability at high speeds;
- stability of handling at various speed modes due to the presence of ribbed structures.
