Check the tread depth regularly.

For safety reasons, tires must be replaced when the tread depth reaches 2-3 mm (4 mm for winter tires).

For safety reasons, it is recommended that the tread depth does not differ by more than 2 mm on the same axle.

The minimum legally permitted tread depth (1.6 mm) is reached when the tread is worn down to the Tread Wear Indicator (TWI). The position of the wear indicators is marked by symbols on the tire sidewalls.

If wear is greater at the front than at the rear, regularly swap the front tires with the rear tires.

Make sure the tires rotate in the same direction.

Tires age even when they are not being driven. We recommend replacing tires every 6 years.
