摘要： The invention relates to a rubber composition that can be used as a tread for a winter tyre having a high grip on melting ice, and comprising at least one diene elastomer such as natural rubber and/or a polybutadiene, more than 30 pce of a liquid plasticizer, between 50 and 150 pce of a reinforcing filler such as silica and/or carbon black, and between 5 and 40 pce of magnesium sulphate microparticles. The invention also relates to the use of such a composition for making treads for winter tyres, as well as to the treads and to the tyres themselves.

摘要： The invention relates to a tire for a vehicle, in particular a winter tire, having a tread comprising a rubber composition that is heat-expandable in the non-vulcanized state and expanded in the vulcanized state, wherein said composition includes a diene elastomer such as natural rubber and/or polybutadiene, 70 to 120 pce of a reinforcing filler such as silica and/or carbon black, between 5 and 25 pce of an expanding agent such as an azodicarbonamide compound, and between 5 and 25 pce of a thermofusible compound having a fusion temperature of between 70 and 150° C, such as urea, the total content of the expanding agent and thermofusible compound being higher than 15 pce, preferably higher than 20 pce. The combined use of the two latter compounds at the recommended high levels strongly enhances the grip of the tire on melting ice.

摘要： The invention relates to a tyre tread comprising: a plurality of tread pattern elements having side surfaces and a contact surface intended to make contact with the road during the rotation of a tyre provided with said tread, the contact limit between the contact surface and the ground forming at least one edge; and a plurality of cut-outs (3) in the form of a groove and/or incision, said cut-outs (3) being defined by opposing side surfaces, and each tread pattern element being formed with at least a first rubber mix (know as the "base mix"). The tread is characterised in that, seen in section in a plane normal to the axis of rotation of the tyre and extending through at least one contact surface of a tread pattern element, at least one of the cut-outs adjacent to said contact surface is covered at least partially with a cover layer and in that the cover layer comprises an assembly of woven or non-woven fibres.

摘要： The invention relates to a rubber composition that can be used as a tire tread having improved adhesion on melting ice, comprising at least one diene elastomer such as natural rubber and/or a polybutadiene, more than 30 pce of a liquid plasticizer, between 50 and 150 pce of a reinforcing filler such as silica or carbon black, and between 2 and 40 pce of microparticles of a water-soluble sulfate of an alkali or alkali earth metal such as a magnesium sulfate, wherein said composition is characterized in that the volumetric microparticle size distribution, measured by laser grading as per ISO Standard 13320-1, satisfies the following relations: 50 μm 50 Span 50 is the diameter of the median particle corresponding to 50% of the cumulative distribution of particles;
Span = (D
90 - D
10 ) / D
50 ; wherein D
10 and D
90 are the diameters of the particle corresponding to 10% and to 90%, respectively, of the cumulative particle distribution. The invention also relates to tire treads incorporating such a composition, as well as to said tires themselves.-
