VEHICLE PNEUMATIC TYRE Russian patent published in 2019 - IPC B60C11/12 B60C11/11 

FIELD: transportation.

SUBSTANCE: present invention relates to pneumatic tires of the vehicle, in particular, for driving in winter conditions. Tread has profile blocks in which lamellas (4) are formed, each of which is provided with two symmetrically passing walls (5) of the lamellae and which in the radial direction consist of three adjacent sections (4a, 4b, 4c) having the radially outer section (4a), which is essentially limited to the section (5a) of the wall extending in the radial direction and which extends to the depth (t₁) from 70 to 90 % of the depth (t) of the lamella (4), the middle section (4b) extending between the radially outer section (4a) and the radially inner section (4c), and the radially inner section (4c), provided with the wall sections (5c), which in their cross section are rounded outwards from the central plane (E).

EFFECT: reduced rolling resistance and improved adhesion with wet surface.
