Pirelli has said that it is the preferred brand for premium and prestige car makers. There are 516 homologations of Pirelli Run Flat tyre, tyres that have been chosen by manufacturers as original equipment for their new cars. This technology allows drivers to keep going even with a puncture so that they can reach their nearest tyre dealer to change the tyre. These are made up of 326 homologations for summer tyres, 100 for winter tyres, and 90 for all season tyres. As a result, Pirelli now has more than 2800 manufacturer homologations for its product range.
Alfa Romeo is the latest marque to have homologated Pirelli Run Flat tyres on its Giulia saloon, but manufacturers such as BMW, Cadillac, Dodge, Jeep, Mercedes, Mini and Rolls-Royce also use Pirelli tyres that can keep going after a puncture. Even when a tyre pressure monitoring system indicates a sudden loss of pressure, these tyres are able to carry on driving for 80 kilometres at a maximum speed of 80kph. The specially-designed sidewall structure is capable of supporting the weight of the car, ensuring a safe journey to the nearest tyre dealer. Pirelli’s bespoke Self Supporting system uses special reinforcements inserted into the sides of the internal structure that are able to withstand both the vertical and horizontal loads on the car.
Pirelli’s Run-Flat technology is available on P Zero, Cinturato, Scorpion and Scorpion Winter, Winter Sottozero 3 and Winter Sottozero Serie II. Run Flat technology responds to the demands of prestige and premium car manufacturers for a level of personalisation precisely tailored to the technical characteristics of their vehicles. Throughout the development process, which takes two or three years, Pirelli’s engineers work hand in hand with their counterparts at each manufacturer to create specific tyres that are distinguished by a special marking on the sidewall, says the company.
