What is the minimum permissible depth of the tyre tread pattern of a lorry?

According to the regulations specifying the technical conditions of vehicles, the minimum tyre tread depth for a lorry is 1.6 mm. This is the limit value, which ensures basic grip and the tyre's ability to disperse water. Driving on tyres with a shallower tread drastically increases the risk of skidding and losing control of the vehicle, especially on a wet road surface.
