Tread profile of a snow tire

A vehicle including at least two vehicle wheels which are rotatably mounted outside of a longitudinal vehicle axis with a snow tire mounted on each of the at least two vehicle wheels, said snow tire comprising:

• a plurality of profile block rows aligned in a circumferential direction and distributed in an axial direction from a first tire shoulder positioned toward an outside of the vehicle to a second tire shoulder positioned toward an inside of 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 and has a constant width, positioned between the first circumferential channel and the first tire shoulder;
• 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.

A tread profile of tire comprising:

• profile block rows comprising two shoulder profile block rows and at least one additional profile block row arranged between the two shoulder profile block rows;
• 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 the tire shoulder profile block rows to the first circumferential channel and a second circumferential channel, which is straight and has a constant width, positioned between the first circumferential channel and one of the tire shoulders profile block rows;
• the profile block rows including profile block elements, and the profile block elements of at least one of the two shoulder block rows and of the at least one additional profile block row comprising a plurality of substantially transverse and substantially sinusoidal sipes separated from each other that extend in a longitudinal direction;
• the substantially sinusoidal sipes being arranged such that, along a depth in a radial direction, at least one substantially sinusoidal sipe is continuously phase-shifted in the longitudinal direction, the phase-shift occurring along a line of inclination oriented at an angle α, with respect to the radial direction, and at least one adjacent sipe positioned adjacent to the at least one substantially sinusoidal sipes is continuously phase-shifted in a direction opposite the longitudinal direction, the phase-shift occurring along a line of inclination oriented at an angle β, with respect to the radial direction,
• whereby, the lines of inclination for adjacent substantially sinusoidal sipes are arranged to form a twist angle γ+α+β, which is a measure for twist of the substantially sinusoidal sipes;
• and
• the twist angle γ of the at least one tire shoulder profile block elements is greater than the twist angle γ of the at least one additional profile block elements.

A snow tire comprising:

• a plurality of profile block rows aligned in a circumferential direction composed of a plurality of profile block elements;
• a first tire shoulder adapted to be positioned toward an outside of the vehicle during an operational state of the tire;
• a second tire shoulder adapted to be positioned toward an inside of the vehicle during an operational state of the tire;
• a first circumferential channel which is straight with a constant width positioned to form a handling region located between the first tire shoulder and the first circumferential channel and a winter region located between the second tire shoulder and the first circumferential channel;
• a second circumferential channel which is straight with a constant width positioned within the handling region;
• and
• the profile block elements located within the handling region having a greater stiffness than the profile block elements located within the winter region.
