Abstract:
Tread profile of a snow tire for a vehicle, comprising:a plurality of profile block rows aligned in a circumferential direction and distributed in an axial direction from a first tire shoulder adapted to be positioned toward an outside of the vehicle in an operational state of the tire on the vehicle to a second tire shoulder adapted to be positioned toward an inside of the vehicle in an operational state of the tire on the vehicle; a plurality of channels aligned in a circumferential direction and being arranged to axially separate the plurality of profile block rows from each other; the plurality of channels comprising a first circumferential channel, which is straight and has a constant width, positioned to divide the tread profile into two axial regions of functionally different structure, each axial region axially extending from one of the first and second tire shoulders to the first circumferential channel, and a second circumferential channel, which is straight with a constant width, positioned between the first tire shoulder and the first circumferential channel; and the plurality of profile block rows comprising a plurality of profile block elements, the plurality of profile block elements in the axial region extending from the first circumferential channel to the first tire shoulder having a higher lateral thrust stiffness than the plurality of profile block elements in the axial region extending from the first circumferential channel to the second tire shoulder.
