What are OE (original equipment) tires?
OE (original equipment) tires are the tires that are fitted to a car at the time of its manufacture.
Are marked tires necessarily approved by individual car manufacturers?
Marked tires are the result of a specific demand expressed by individual car manufacturers. They indicate that careful attention has been paid to the tire and model package in order to deliver the level of performance owners expect. For example, 'N'-marked MICHELIN tires are designed especially for Porsches, 'K'-marked tires are designed for Ferraris and 'T'-marked tires are designed for Teslas.
Marked tires designed for different car models are the fruit of research carried out jointly by MICHELIN engineers and their counterparts at the carmaker in question. For instance, 'N'-marked tires are approved by Porsche. Marked tires are therefore approved by the manufacturer in question
Is there a difference between a tire that has been approved by a car manufacturer and a type-approved tire?
All tires must comply with the legislation of the country or region where they are sold. This is not the same thing as a tire being approved by an individual car manufacturer, which is not a mandatory process.
