Abstract
A tire (1) in which at least one of the said tread pattern blocks (51) comprises a circumferential reinforcing element (52) positioned axially on the inside relative to the said at least one groove (71) when working from the outside towards the inside and axially close to the said circumferential groove, the circumferential reinforcing element (52) is made of a rubber compound having a dynamic shear modulus G* at least twice as high as the dynamic shear modulus G* of the rubber compound of the rest of the blocks of the tread, the circumferential reinforcing element (52) extends radially from the radially exterior surface of the said crown reinforcement (6) towards the surface of the said tread with an axial width which decreases progressively with increasing radial proximity to the outside, and in which the said circumferential reinforcing element (52) partially forms the axially internal lateral face (7i) of the said at least one of the said tread pattern blocks (51).
