PNEUMATIC HAVING IMPROVED WEAR AND ROLL RESISTANCE PROPERTIES

摘要

The invention relates to a tire comprising a crown reinforcement consisting of at least one layer of circumferential reinforcement elements. According to the invention, the tread is formed of a layer of polymeric mixture forming the tread surface whose ratio of the maximum value of tan (d), denoted tan (d) max, measured at 60.degree. the forward cycle on the complex dynamic shear modulus G *, measured at 25% and 60 ° C on the forward cycle, is less than 0.065 and the product of the complex dynamic shear modulus G *, measured at 25% and 60 ° C on the forward cycle of said polymeric mixture layer forming the running surface by the elongation breaking deformation value of said layer of polymeric mixture forming the tread surface being greater than or equal to 1280 MPa.
