The German brand Porsche builds high performance vehicles which require tyres adapted to these performances. To this end, Porsche integrated tyre selection in the development process of each vehicle. Tyres which have undergone the tests and obtained validation by Porsche are then accredited with an "N" specification.
The Porsche specifications are as follows: N0, N1, N2, N3, etc. These indications on the side of the tyre mean that these tyres have been accredited by Porsche. The numbers following the "N" code: 0, 1, 2, 3 represent the various accreditations by Porsche over time. This means that N0 was the first tyre accredited. Thereafter, based on the modifications made on the tyre, this same reference is identified as N1, then N2, etc. When a new tyre is selected by Porsche, the index starts at N0 once again. Watch out, it is absolutely necessary to select tyres accredited by Porsche as these have been designed for your car. |

It is important to fit tyres from one manufacturer only and of one type only (N1, N2, etc.) on your vehicle, in order to avoid having your car behave erratically.
