TREAD BLOCK STRUCTURE FOR PNEUMATIC TIRE OR TREAD LAYER Russian patent published in 2021 - IPC B60C1/00 B60C11/03 B60C11/12 

FIELD: automotive industry.

SUBSTANCE: invention relates to the automotive industry. The structure (200) of tread blocks suitable for a pneumatic tire (100) or for a tread layer (150) of a pneumatic tire (100). The tread block structure (200) comprises a middle block (210) extending through the tread block structure (200) in the longitudinal direction (SC, SL); primary shoulder blocks (220); secondary shoulder blocks (230); primary intermediate blocks (240) located in the transverse direction (ST, AX) between some of the primary shoulder blocks (220) and the middle block (210); and secondary intermediate blocks (250) located in the transverse direction (ST, AX) between some of the secondary shoulder blocks (230) and the middle block (210). The middle block (210) contains primary transverse parts (212) and secondary transverse parts (214) such that [A] at least half of the primary intermediate block (240) is located longitudinally (SC, SL) between the two primary transverse parts (212) of the middle block (210) and [B], at least half of the secondary intermediate block (250) is located longitudinally between the two secondary transverse parts (214) of the middle block (210). The structure (200) of the tread blocks can be implemented on a pneumatic tire (100) or a tread layer (150).

EFFECT: improved traction on snowy, icy and dry roads.
