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 emergency spare wheel/spare wheel.

The service life of tires depends on the following factors amongst other things:

driving style
tire pressure
mileage
