Find the officially approved tire sizes for your vehicle based on FEDRO 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.
Enter your type approval number (field 24 on the vehicle registration certificate) or search by brand and model. You will get all approved sizes with matching wheel specifications. This data is essential when changing tires or buying wheels.
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.
