The depth of the main grooves in the tread must be at least 1.6 mm on summer tyres and at least 3.0 mm on winter tyres. The main grooves are the wide grooves in the central area of the tread on about 3/4 of the tread surface.

Studded winter tyres can be used from November 1 to March 31 or until Easter Monday. Studded tyres can be used at other times if the weather or driving conditions require them.
