• Only mount tires and wheels of the same type and make.
• Only mount tires of the correct size onto the wheels.
• After mounting new tires, run them in at moderate speeds for the first 60 miles (100 km) as they only reach their full performance after this distance.
• Do not use tires that are excessively worn as the tire traction on wet road surfaces decreases significantly when the tread depth is less than 1/8 inch (3 mm).
• Replace the tires after six years at the latest, regardless of wear. This also applies to the spare wheel/emergency spare wheel.

The service life of tires depends on the following factors amongst other things:
• driving style
• tire pressure
• mileage
