Until recently, the summer tire Michelin Pilot Exalto A/S was only available on the North American market. However, today domestic car enthusiasts can also appreciate its excellent characteristics. This model is offered by the manufacturer in 25 sizes with a wheel mounting diameter of 14 to 17 inches and a speed index of H and V. This suggests that the main buyers of this tire are owners of small and medium-sized cars.
HydroChutes Drainage Channels
One of the characteristic features of this model is its exceptional resistance to aquaplaning. This was achieved largely due to the four longitudinal channels located in the central part of the tread. These elements are distinguished by very impressive sizes, which allows for the rapid removal of huge amounts of water from the contact patch. At the same time, the French tire makers were able to further increase the performance of the drainage system by supplementing it with a multitude of wedge-shaped water drainage channels. Their size, as well as the original shape, contributes to an increase in the speed of water circulation, which has become even faster to leave the contact patch. This made the grip with the wet road much more reliable and stable.
V-shaped Tread Pattern Design
This choice of French tire makers can be explained by the extremely versatile characteristics of the V-shaped tread pattern, which is very relevant for a tire designed for various weather conditions.
In this variation, the V-shaped tread pattern consists of three main functional zones - the central part and a pair of shoulder zones. The central part of the Michelin Pilot Exalto A/S tread consists of three longitudinal ribs, which provide excellent directional stability.
A characteristic feature of this tread pattern is the longitudinal rib located in its very center. It consists of double arrow-shaped blocks, the massive size of which provides them with high structural rigidity, which has a beneficial effect on handling. At the same time, the numerous gripping edges created by them have made it possible to significantly increase the effectiveness of braking and acceleration.
Life Maximized Adherence
This term hides a whole complex of technological solutions aimed at ensuring a long service life of the tire. The first component of this system is the above-mentioned V-shaped tread pattern. The fact is that such a arrangement of elements, combined with their shape and massive size, provides a very even distribution of external pressure over the contact patch. Due to this, it was possible to significantly reduce the likelihood of uneven wear, leading to a reduction in the service life of the tire.
The rubber compound is also one of the means of achieving long service life. Its composition includes special components, including silica, which significantly increased the resistance of the tread to abrasive wear and reduced rolling resistance at the same time.
The design of the carcass also affected the service life of the tire. It is distinguished by its multi-layered structure, which made it possible to make the tire both light and very strong. In addition, the alternation of layers with different degrees of stiffness also contributed to a more even distribution of the load over the contact patch, while ensuring high resistance to dynamic deformations, which further increased the resistance to uneven wear.
Main Features of Michelin Pilot Exalto A/S
- The original V-shaped symmetrical directional tread pattern is perfectly adapted for summer operation;
- Three longitudinal ribs located in the central part of the tread provide excellent directional stability, regardless of the characteristics of the road surface;
- HydroChutes drainage channels in combination with a multitude of wedge-shaped channels have made it possible to achieve excellent resistance to aquaplaning;
- Double blocks of the central rib improve the efficiency of acceleration and braking on a wet road;
- Exceptional resistance to wear due to special components in the composition of the rubber compound, the multi-layered structure of the carcass and tread, as well as the V-shaped design of the tread pattern, which provided a very even distribution of load over the contact patch.
