Its appearance owes to two factors. Firstly, it is the introduction of a new tire labeling system in the European Union, which allows uninformed buyers to assess its operational characteristics. The second factor is the popularity of the Centurato P7 model, whose design was used in the development of this tire. The novelty differs from the "original" not only in the presence of new labeling but also in the highest ratings for traction on wet roads, economy, and durability. At the same time, the target audience remains the same - car owners who value a combination of sporty handling and comfort.
Optimal distribution of external pressure on the contact patch
As mentioned earlier, this model is distinguished by a high level of comfort while driving. This is largely achieved due to the very even distribution of external pressure on the contact patch. This was made possible by the five-rib structure of the asymmetric tread pattern. The tread blocks are arranged in longitudinal ribs in such a way that they form a continuous point of support, stretching across the entire tread. In addition to reducing noise, this technical solution significantly increases the service life of the entire tire due to increased resistance to uneven wear.
Three rigid central ribs
Despite differences in construction, the three central ribs have one common feature - high structural rigidity. This is ensured by the massive size of these tread elements, as well as the absence of any breaks throughout their length. The presence of such a number of rigid longitudinal ribs allows the central part of the tread to demonstrate high resistance to dynamic deformation. This feature gives the tire excellent directional stability when driving at any speed, as well as enviable fuel efficiency due to reduced rolling resistance.
Four longitudinal drainage grooves
In accordance with the new labeling for Pirelli Cinturato P7 Blue tires sold in the European Union, this model has the highest ratings for traction on wet roads. This is largely due to the drainage system. Its main components are four longitudinal grooves that separate the main functional zones of the tread. They are characterized by a significant internal volume, ensured by both the width and the significant depth of the tread. This design feature allows for the removal of almost any amount of water from the contact patch, leaving it practically dry, thus providing excellent traction with the road even in very unfavorable weather conditions.
Innovative tread rubber compound
Unfortunately, information on the composition of the tread rubber compound of this model from the Italian tire manufacturer, like any other, is extremely scarce. It is precisely its physical properties that determine almost all the main working characteristics of the tire. But something is still known. In addition to the increased content of silicon-containing components, better known as silica, the Cinturato P7 Blue rubber compound contains special functional polymer compounds. With their help, the tread has acquired the ability to maintain elasticity at an optimal level, regardless of the temperature conditions of the external environment. The result of such technical tricks was not only excellent traction on wet roads and increased resistance to abrasive wear but also exceptional stability of the traction properties, which significantly simplifies the process of managing the vehicle.
Main features of the Pirelli Cinturato P7 Blue tire
- the highest ratings for traction on wet roads, economy, and durability according to the new EU labeling for tires;
- the asymmetric directional tread pattern is optimized for operation on any summer roads;
- the even distribution of external pressure on the contact patch improves the level of comfort and extends the service life of the tire due to increased resistance to uneven wear;
- three rigid longitudinal ribs reduce rolling resistance, increase directional stability when driving at high speeds, and provide precision and quick response of the tire to steering wheel turns;
- exceptionally high resistance to aquaplaning, thanks to a high-performance drainage system, which includes four longitudinal grooves with a large internal volume;
- the innovative rubber compound maintains elasticity at an optimal level over a wide temperature range, thus providing stability of the traction properties, regardless of weather conditions, and also gives the tread excellent resistance to abrasive wear.
