L'invention concerne donc une composition de caoutchouc à base d'au moins un élastomère diénique, 110 à 160 pce (parties en poids pour cent parties en poids d'élastomère) de charge renforçante, un système de vulcanisation et un système plastifiant comprenant au moins une résine hydrocarbonée de température de transition vitreuse (Tg) comprise entre -40°C et 20°C, le taux total de plastifiant étant supérieur ou égal à 70 pce. The invention relates to a rubber composition based on at least one diene elastomer, 110 to 160 pce (parts by weight per hundred parts of elastomer) of reinforcing filler, a vulcanisation system and a plasticising system comprising at least one hydrocarbonated resin having a glass transition temperature (Tg) of between -40°C and 20°C, the total amount of plasticiser being higher than, or equal to, 70 pce.
