Review article

The tyre tread coupling with the road surface depends on a number of both external and internal factors. The controllability of the vehicle depends on the interaction between two materials. The article considers various tyre tread characteristics, the values of the coupling coefficients are determined for the tyre tread of M1 category vehicles during operation on different road conditions. The interaction of a new and worn tyre tread with the road surface has been assessed with vehicles driving on the asphalt concrete surface, taking into account weather conditions.
