Michelin Pilot Sport All Season 4 Acoustic — a hybrid of track philosophy and everyday comfort, adapted for drivers who refuse to compromise between handling, safety, and in-cabin quietness.
Asymmetric tread pattern
Designed based on data collected on racing tracks, the tyre's tread has an asymmetric architecture. The outer shoulder rib has a maximum area of rubber compound. This deliberate engineering decision is aimed at increasing the contact patch when cornering. It is here that the "grip" is formed, allowing the vehicle to confidently enter turns at high speeds, minimizing lean and loss of trajectory. The inner zone, on the other hand, is optimized for drainage and traction on wet surfaces.
Grip in any conditions
The Extreme Silica+ rubber compound is a mixture with maximum silica content. From a polymer chemistry perspective, the high silica content allows the molecular lattice to maintain elasticity even at low temperatures, while providing adhesion to the unevenness of the asphalt surface.
An additional booster is the Helio+ technology. This is an advanced polymer modifier that maintains the working elasticity of the compound in negative temperatures.
Lamellas working as a system
The tread is equipped with 360-degree variable lamella technology. These are not just notches, but interconnected three-dimensional elements that create multiple additional gripping edges. When in contact with the road, each lamella opens and closes depending on the vector of the applied force, providing traction both when accelerating and braking.
Evenness as a resource
One of the key engineering innovations is the Dynamic Response technology. Developed on the track and tested on ordinary roads, it provides an even distribution of forces and temperatures across the entire tread surface. From a physics perspective, this means the absence of local overheating and point wear. The result is an increased operational resource.
Quietness as an engineering parameter
The acoustic modification of the tyre is a full-fledged technological solution. Inside the tyre, a special sound-absorbing layer is integrated, which effectively dampens the resonant frequencies that occur when in contact with the road surface. The noise level in the cabin is reduced by approximately 20%.
Key features of Michelin Pilot Sport All Season 4 Acoustic:
- all-season versatility - the tyre maintains elasticity and grip in a wide range of temperatures;
- the built-in Michelin Acoustic technology reduces the noise level in the cabin by approximately 20%;
- the model demonstrates the best-in-class braking distance - the result of advanced compound chemistry and lamella architecture;
- the Dynamic Response technology provides an even distribution of loads, extending the life of the tread;
- the asymmetric pattern with an enhanced outer shoulder guarantees exceptional lateral grip and precision in turns, characteristic of track tyres.
