Title (EN) A TIRE COMPRISING A TREAD
(FR) PNEU COMPRENANT UNE BANDE DE ROULEMENT
Abstract:
(EN) A tire comprises a tread which comprises a plurality of tread pattern elements (1) delimited by cut-outs (3, 4), the tread pattern elements respectively comprising at least one lateral face (13, 14, 15, 16), and a first rubber composition (FC) at least partially covered on at least one of the lateral face (13, 14, 15, 16) with a layer of a second rubber composition (SC) based on an elastomer matrix comprising more than 55 phr and up to 100 phr of a first diene elastomer having a glass transition temperature of less than -25℃ and 0 to less than 45 phr of a second diene elastomer, a reinforcing filler comprising more than 100 phr of a reinforcing inorganic filler, and more than 45 phr of a plasticizing agent predominately comprising at least one hydrocarbon resin having a glass transition temperature of more than 20℃.
(FR) La présente invention porte sur un pneu comprenant une bande de roulement qui comprend une pluralité d'éléments de motif de bande de roulement (1) délimités par des découpes (3, 4), les éléments de motif de bande de roulement comprenant respectivement au moins une face latérale (13, 14, 15, 16), et une première composition de caoutchouc (FC) qui est au moins partiellement recouverte sur au moins l'une des faces latérales (13, 14, 15, 16) avec une couche d'une seconde composition de caoutchouc (SC) sur la base d'une matrice élastomère comprenant plus de 55 pce et jusqu'à 100 pce d'un premier élastomère diénique ayant une température de transition vitreuse inférieure à -25°C et 0°C à moins de 45 pce d'un second élastomère diénique, une charge renforçante comprenant plus de 100 pce d'une charge inorganique renforçante, et plus de 45 pce d'un agent plastifiant comprenant majoritairement au moins une résine hydrocarbonée ayant une température de transition vitreuse supérieure à 20°C.
