Abstract

Improvements in tires for motor vehicles, comprising a carcass and a tread, characterized essentially by the fact of constituting this tread by two circumferential and mutually contiguous portions, of which a first portion is formed by an elastomeric composition suitable for developing adhesion on snowed and/or frozen ground, while the second portion is constituted by an elastomeric composition suitable for developing adhesion on dry and/or wet soil, the first circumferential portion being provided, in correspondence of the outer surface, with a different drawing from that of the outer surface of the second portion, the transition temperature of the second order of the elastomeric composition of the first portion being between -30 and -55º c, and the transition temperature of the second order of the elastomeric composition of the second portion, between -10 and -25ºc.
