Sumo Firenza ST-09

Sumo Firenza ST-09 — a summer tire designed for installation on a wide range of passenger cars of various classes. It is created for those who value a high level of comfort, safety, and stability of characteristics.

The tread base features three ribs, the central one having a solid structure, while the others are supplemented with diagonal grooves. This architecture performs several functions at once:
- stabilizes the vehicle on a straight trajectory;
- increases the responsiveness of steering;
- improves traction with the road surface, especially during active driving.

Thanks to the optimized arrangement of tread elements, it was possible to reduce the formation of air vortices. This solution directly affects acoustic comfort: the level of noise transmitted to the cabin remains minimal even when moving at high speeds.

One of the key advantages of the model is the significantly reduced braking distance. The effect is achieved due to the special geometry of the block structures and the use of an innovative rubber compound. The compound includes high-dispersion silica, which:
- maintains the elasticity of the rubber in hot weather;
- increases the grip properties on a wet surface;
- provides confident braking and acceleration in any summer conditions.
To protect against hydroplaning, it is equipped with both ring and diagonal channels, which quickly remove moisture from the contact area. This allows maintaining stability and control even during heavy rain, reducing the risk of skidding.

The main features of Sumo Firenza ST-09:
- a summer model for a wide range of passenger cars;
- three central ribs with notches increase steering precision;
- sharp edges of lamellas and block structures reduce the braking distance;
- a compound with silica guarantees reliable traction.
