PNEUMATIC TIRE Russian patent published in 2012 - IPC B60C19/08 B60C11/00 B60C1/00 B29D30/60 

FIELD: automobile industry.

SUBSTANCE: this invention covers automobile tire tread design. A pneumatic tire includes a tread rubber consisting of the layers; each layer is modeled by overlapped reeling of a rubber tape. This rubber tape contains a conducting portion in each layer in longitudinal direction and least conducting portion, where conducting portion is reeled on the tire at least once. In the most outer radial layer the conducting portion protrudes the tread for the overall axial length of at least 1.00 mm. In the most inner radial layer the conducting portion protrudes the radial outer surface, so that to be electrically connected to the conducting below structure at the overall axial length of at least 1.00 mm. Between radially adjacent layers the conducting portion of the outer layer is interlocked with the conducting portion of the radially inner layer at the overall axial length of at least 1.00 mm. The rubber tape shall be preferably made of a mixture enriched by silicon dioxide.

EFFECT: improvement of adhesion between the spins for enhancement of tread service life.
