Abstract (en)

[origin: EP0864446A1] A method for reducing the working temperature of a tire tread (10) for vehicles utilizing a tire tread (10) consisting of a first portion (A), comprising 100 parts by weight of an elastomeric material, 40-120 parts by weight of a filler, comprising from 50 to 100% by weight of carbon black and from 0 to 50% of silica, and 3-40 parts by weight of at least a conventional additive, and a second portion (B), comprising 100 parts by weight of an elastomeric material, 40-120 parts by weight of a filler, comprising from 30 to 100% by weight of silica and from 0 to 70% of carbon black, and 3-40 parts by weight of at least a conventional additive provided, however, that the silica content in portion (B) is at least 20% higher than in portion (A). The tires where the area of said portion A exceeds 37,1% of the total area of the tire tread are novel and are a further object of the invention. <IMAGE>
