    摘要: A method of forming a tire component comprising a first rubber compound and a second rubber compound is disclosed. The method comprises the steps of:
    (i) extruding a first rubber compound through a main extruder (20) and a main gear pump (25);
    (ii) extruding a second rubber compound through a second extruder (40) and a second gear pump (42) into the main extruder (20);
    (iii) varying or tuning the ratio of the first compound to the second compound by adjusting the speed of the main gear pump (25) and/or the speed of the second gear pump (42) to obtain a first blend ratio of the first compound to the second compound and then applying a first rubber profile directly onto a tire building machine (95) to form a first zone of rubber having the first blend ratio; and
    (iv) adjusting the speed of the main gear pump (25) and/or the second gear pump (42) to obtain a second blend ratio of the first compound to the second compound, and then applying a second rubber profile formed of the first compound and the second compound to form a second zone of rubber having the second blend ratio. Also, a pneumatic tire comprising a tire component with two or more adjacent zones of different mixtures of rubber is disclosed. The transition in terms of rubber composition from one of said zones to an adjacent zone is continuous.

    摘要: The invention relates to an elastomer laminate comprising three layers, the first layer consisting of a diene rubber composition comprising a first elastomer matrix; the second layer consisting of a diene rubber composition comprising a second elastomer matrix, which second elastomer matrix comprises a second ethylene terpolymer elastomer consisting of an α-olefin and an unconjugated diene and containing more than 10% by mass diene units; the third layer consisting of a diene rubber composition comprising a third diene elastomer with a diene unit mass rate greater than 50%, the second layer being disposed between the first layer and the third layer. A laminate of this type has good resistance to separation of its constituent layers.

    摘要: A pneumatic tire including: on a tread of the tire, inclined belt layer and circumferential belt layer; and on the tread surface, a plurality of circumferential grooves extending in the tread circumferential direction, and shoulder land portions partitioned between the circumferential grooves located outermost in the tire width direction and tread ground contact ends. Positions of the tread surface that correspond to the outermost ends of the circumferential belt layer in the tire width direction are within the shoulder land portions, and the distance in the tire width direction between the outermost ends in the tire width direction of the circumferential belt layer and tire equator side ends of the shoulder land portions is 12 % or more and 22 % or less of a half of the width of the circumferential belt layer in tire width direction.
