Run Flat tires, 20 years of Pirelli innovation

by admin

ROME – Twenty years ago Pirelli introduced the “Run Flat” technology, the result of the experience gained in the field of rally racing, with the aim of allowing driving to continue even in the event of a tire puncture. Continuous research has then led to new technological solutions in the structure of the tire and to the evolution of the materials used, optimizing comfort and improving the tire’s rolling resistance, updates that have led to a reduction in consumption and emissions.

A “transversal” technology that we also find on new electric cars where, to make room for batteries, spare tires are very often not provided, which is why car manufacturers are choosing solutions such as Run Flat or Self Sealing. In these twenty years, Pirelli engineers have developed over a thousand tire models with Run Flat technology, which allows you to continue driving for 80 kilometers at a maximum speed of 80 km / h. A simple and safe solution adopted by many manufacturers who have equipped their models with Run Flat tires as original equipment. During this period, Pirelli has produced more than seventy million tires with this technology, including summer, winter and all-season tires, and is present on over 50 tire models within the Pirelli homologation range for car manufacturers.

All these tires have the dedicated “Run Flat” marking on the shoulder as well as that of the car brand. Not only Run Flat because on some Pirelli tire models this technology is combined with specific Elect and Pncs technological solutions. The first dedicated to electric vehicles and focused on low rolling resistance, the reduction of the noise emitted by the rolling of tires, with a special structure designed to support the weight of a battery-powered vehicle. The second system, on the other hand, aims to reduce the noise emitted by rolling that is perceived in the passenger compartment, thanks to the use of a particular sound-absorbing material present in the tire.

Then there is the “Seal Inside” another Pirelli anti-puncture solution which, in the event of a puncture up to 4 mm, thanks to the presence of the sealing material inside the tire, forms a sheath that envelops the foreign body from the moment to it penetrates, thus preventing the escape of air and the consequent loss of pressure. Once the “intruder” has been extracted, the material itself seals the exit hole, allowing you to continue driving safely and in total comfort as if nothing had happened. Finally, it should be noted that the top of the range Run Flat tires benefit from the innovative Pirelli Mirs production process, entirely supervised by computer and characterized by the production of the “raw” tire made by robots, which guarantees a final result with high quality standards and product reliability.
