Rotalla RX9 — a summer tire designed for modern passenger cars, rethinking the balance between dynamics, safety, and efficiency. The model is created for drivers who value the thrill of driving and demand uncompromising precision in handling on dry and wet asphalt.
Asymmetry as the basis of stability
The tread pattern features functionally divided zones, each solving its own problem. The central part, represented by three ribbed structures, provides directional stability and maximum contact patch in turns. As for the shoulder area, it is responsible for stability during maneuvering and actively participates in protection against lateral displacement.
Technological advancement
The optimized central zone with a monolithic rib forms a stabilizing "backbone". This design minimizes carcass deformation during sharp maneuvering, providing an instant and predictable response to steering commands. The ribs in the middle zone are equipped with a combination of wavy and wedge-shaped lamellas. They work in sync: the wedges "cut" through the water film, while the wavy channels create a turbulent flow for its effective "suction" and removal from the contact patch. The result is high aquaplaning resistance even at high speeds.
The wide blocks in the outer shoulder, connected by arc-shaped lamellas, provide maximum stiffness to lateral loads. This gives exceptional stability and feedback in tight turns, preventing tire deformation.
Another feature is the innovative polymer blend with increased silica content and special resins. It maintains optimal elasticity over a wide summer temperature range, actively resisting overheating. This directly affects wear resistance and consistency of traction properties.
Key features of Rotalla RX9:
- uncompromising directional stability on straights and in long high-speed turns thanks to a rigid carcass and a solid central zone;
- direct and informative steering response, allowing for full control over the vehicle's trajectory;
- high level of grip and short braking distance due to effective water removal and special rubber compound;
- reduced rolling resistance due to an optimized profile and composition, which positively affects fuel efficiency.
