Michelin Primacy 3 S1

The summer tire Michelin Primacy 3 S1 is a special version of the same model with the Run Flat system. The tire is distinguished by its ability to be used when mechanical damage occurs that leads to a loss of pressure inside. It is provided with a number of design features, which will be discussed below.

Reinforced sidewalls

One of the distinctive features of the tire is the reinforced sidewalls. The increased stiffness of these bearing elements allows the tire to maintain its original shape when the pressure inside is lost. This ensures safety while driving and protection against uneven wear. In the absence of damage, this feature significantly reduces rolling resistance and fuel consumption along with it.

Optimized compound

The tire's tread is made from a rubber mixture whose physico-chemical properties have been selected with the possibility of movement after losing hermeticity. Compared to the compound for regular tires, it differs in increased resistance to abrasion and low heating, which is achieved due to a modified composition that includes special polymeric compounds.

Tread with smoothed edges

A distinctive feature of the tread pattern is the smoothed edges of the forming elements. This improves several operational properties of the tire. Almost all of them are due to the improved stability of the size and configuration of the contact patch.

Main features of Michelin Primacy 3 S1

- is a version of the same model with the RunFlat system
- reinforced sidewalls maintain their shape when hermeticity is lost;
- modified composition of the rubber mixture, which has improved resistance to abrasion and heating.
