    摘要： The invention relates to a tyre comprising a tangential direction XX', an axial direction YY' and a radial direction ZZ' and comprising at least one carcass reinforcement (2) surmounted radially on the outside by a crown reinforcement (3), itself radially on the inside of a tread (4), the said crown reinforcement (3) consisting of at least one layer of reinforcing elements, the said tread comprising reinforcers (8) and being connected to two beads (5) by two sidewalls (6), the said beads (5) being intended to come into contact with a rim, each bead (5) comprising at least one circumferential reinforcing element (7). The tyre is characterized in that the tread (4) is made of a rubber composition having a shear modulus greater than or equal to 0.4MPa and less than 1MPa, in that the reinforcers (8) of the tread (4) have, in the direction in which they are present, an extensibility less than or equal to 30%, and in that the extensibility of the reinforcers is identical or different in the directions YY' and XX' or only in the direction YY'.
