The tyre approval lists represent the results of extensive tests over several weeks carried out by the Porsche tyre experts this summer. They used classic Porsche sports cars and modern classics such as a 356, a 911 Carrera G model, a 911 Turbo (930) and a first generation Porsche Boxster (986) for these tests. Such tests take place on a regular basis to test and approve newly developed tyres for classic Porsche cars. The approval is also documented by the so-called N marking on the tyre flank.
Porsche is the only manufacturer that performs such an extensive service for older models, ranging from those 356 models that are over 50 years old, through all the 911 generations and the transaxle models 924/944/968 and 928, right up to the first Boxster (986). This is justifiable as around two thirds of all Porsche sports cars ever built are still driving more or less regularly on our roads.
With these tyre tests for classic sports cars, Porsche ensures that these older models also profit from the progress made in tyre development and can take advantage of the modern tyres that are tailored to meet their requirements. This benefits driving behaviour and driving safety with regards to grip on wet roads and shorter braking distances.
