Approved tires: official Swiss data

Every vehicle registered in Switzerland has a list of tire sizes approved by the Federal Roads Office (FEDRO). This data comes from type approvals (TARGA) and determines which tire sizes you can legally mount. Our tool displays standard and optional configurations with wheels, offset, load and speed ratings.

Why respect the approval?

Mounting non-approved tires can lead to inspection failure, fines, or even insurance cancellation in case of an accident. Always check that your tires match the approved sizes for your vehicle.
