摘要：A tread for tire comprising a rubber composition, said composition comprising at least a dienic elastomer, a reinforcing filler and a plasticizing system, characterized in that the said plasticizing system comprises a combination of: a hydrocarbonated plasticizing resin having a vitreous transition temperature higher than 0 °C; and a carboxylic acid diester having the formula R - OOC - (CH<SUB>2</SUB>)<SUB>n</SUB> - COO - R, in which n is comprised between 1 and 15 and the R radicals, whether identical or different, represent a hydrocarbonated radical. The invention also relates to the use of such a tread for tire manufacturing or retreading having a compromise of substantially improved characteristics concerning wear and adherence to wet surfaces.
