A pneumatic tire comprising reinforcing elements DISTRICT

摘要

1. A tire with radial carcass reinforcement comprising at least two vertex working layer reinforcement elements, crossed from one ply to the next, forming with the circumferential direction angles of between 10 ° to 45 °, wherein the layer C of the rubber composition is at least, between the edges of said at least two working layers vertex and the vertex armature radially covered tread wherein said tread is connected to the two sides with flanges, wherein the crown reinforcement comprises at m D, one layer of circumferential reinforcing elements, characterized in that the modulus of elasticity under tension at 10% elongation of the layer C exceeds 9 MPa, the maximum value of tan (δ), denoted tan (δ), the layer C is less than 0,100.2. The pneumatic tire according to claim. 1, characterized in that the layer C of the rubber composition is an elastomer mixture based on natural rubber or synthetic polyisoprene with a majority of cis-1,4 chains and, if appropriate, at least one other diene elastomer, the natural rubber or synthetic polyisoprene in the case of a mixture having a majority proportion in relation to the proportion of the other or used by other diene elastomer and a reinforcing filler, formed: a) a carbon black with BET specific surface area of ​​less than 60 m / g, Nez tive of its structure index used with a share ranging from 40 to 100 phr and preferably from 60 to 90 phr, b) a white filler-type silica or alumina having surface functional groups of SiOH and / or AlOH, selected from the group formed by deposition or pyrolysis silicas, alumina or aluminosilicates, either as carbon black, modified
