A tire is equipped with a radiofrequency communication module with a carcass reinforcement comprising two carcass plies such that the communication module is positioned in the bead axially on the outside of and against the second carcass ply.

Tire provided with a radio frequency communication module

Tire () comprising a directional tread () comprising a plurality of blocks () extending continuously along an overall curvature C from one of the edges () towards the centre () of said tread, all or some of the blocks () of the tread comprising a median sipe () of length S extending along a curvature C' substantially identical to the curvature C of the block, each block () comprising a central zone at an angle &#x3b2;1 such that 35&#xb0;&#x2264;&#x3b2;1&#x2264;65&#xb0;, an edge zone at an angle &#x3b2;3 such that 0&#xb0;&#x2264;&#x3b2;3&#x2264;10&#xb0;, and an intermediate zone between the central zone and the edge zone at an angle &#x3b2;2 allowing continuity between the three zones, at least some of the blocks () being designed with a block chamfer () provided at the trailing edge in the intermediate zone and/or the edge zone.

Tire with a directional tread comprising curved blocks with chamfers

Tire comprising a directional tread that has two edges and a center. The tread comprises a plurality of blocks, each block extending continuously along an overall curvature C from one of the edges towards the center of the tread, forming a block central end provided with a central wall. Each block has a width WB and a length LB, this width increasing from the block central end in the direction of the edge. All or some of the blocks of the tread include a median sipe of length S and extending from the block central end along a curvature C' substantially identical to the curvature C of the block.
