Title
(EN) TREAD OF A TYRE WITH IMPROVED GRIP ON WET GROUND
(FR) BANDE DE ROULEMENT DE PNEUMATIQUE A ADHERENCE AMELIOREE SUR SOL MOUILLE
Abstract
(EN)
A tyre with improved grip on wet ground, the tread of which comprises a rubber composition comprising at least(parts by weight per hundred parts of elastomer): - 50 to 100 phr of a styrene- and butadiene-based copolymer, in particular a styrene-butadiene (SBR) copolymer; - optionally, 0 to 50 phr of another diene elastomer, such as, for example, a polybutadiene or natural rubber; - 100 to 150 phr of a reinforcing inorganic filler such as silica; - and a plasticizing system comprising: - in an amount A of between 10 and 60 phr, a thermoplastic hydrocarbon-based resin which has a Tg above 20°C; - and in an amount B of between 10 and 60 phr, a liquid plasticizer; - it being understood that the total amount A + B is greater than 50 phr, preferably between 50 and 100 phr.
(FR)
Pneumatique à adhérence améliorée sur sol mouillé, dont la bande de roulement comporte une composition de caoutchouc comprenant au moins(parties en poids pour cent parties d'élastomère): - 50 à 100 pce d'un copolymère à base de styrène et de butadiène, en particulier un copolymère styrène-butadiène(SBR); - optionnellement, 0 à 50 pce d'un autre élastomère diénique tel que par exemple un polybutadiène ou du caoutchouc naturel; -100 à 150 pce d'une charge inorganique renforçante telle que de la silice; - un système plastifiant comprenant: - selon un taux A compris entre 10 et 60 pce, une résine hydrocarbonée thermoplastique présentant une Tg supérieure à 20°C; - selon un taux B compris entre 10 et 60 pce, un agent plastifiant liquide; - étant entendu que le taux total A+B est supérieur à 50 pce, de préférence compris entre 50 et 100 pce.
