FIELD: vehicles.
SUBSTANCE: invention relates to winter tires. The ice grip device comprises a housing configured to enter a recess in the tire tread, and a stud connected to the body, where the body contains an upper flange connected to the stud, a rod and a lower flange located close to each other along the longitudinal axes. The cross-sectional area of the bar is less than the cross-sectional area of the top flange and bottom flange, respectively. The lower flange includes a main part centred on the longitudinal axis and a part with one tail, which extends radially outward from the main part with respect to the longitudinal axis.
EFFECT: improved adhesion force of winter tires, as well as increased reliability of fixing the device for gripping ice in the tire tread.
