    摘要： A pneumatic tire has a tire skeleton portion in which a plurality of arranged reinforcing cords are covered by a rubber layer. The reinforcement cords are organic fiber cords formed from polyethylene terephthalate. The organic fiber cords have an intermediate elongation (2.0 cN/dtex) of 3.0% to 4.0%, a dimensional stability index of 5.0% to 6.5%, and a difference between an elongation ratio at a strength at 70% the strength at the time of breaking and an elongation ratio at the time of breaking in a strength-elongation curve of 11% to 16%.

    R measured in the direction Y of between 2 and 100 mm and has a thickness E
    R measured in the direction Z of between 0.1 and 5 mm, the L
    R /E
    R ratio being greater than 3. Said multi-composite band comprises at least a plurality of monofilaments (10) which are made of composite material and are oriented in the direction X, comprising filaments made of an inorganic material (101) which are embedded in a thermoset resin (102), the glass transition temperature (Tg
    1 ) of which is greater than 70 °C. Said monofilaments are coated in a layer of thermoplastic material (12). The invention also relates to a multi-layered laminate comprising such a multi-composite planar reinforcement. The invention further relates to a pneumatic or non-pneumatic tyre, which is reinforced with such a multi-composite reinforcement or such a multi-layered laminate.

    摘要： Provided is a steel cord for reinforcing a rubber article, which has an improved durability against so-called cuts, such as notches and perforations, which are generated in the case of treading on an obtusely or sharply pointed projection, without decreasing the strength in the axial direction of the cord, and without increasing the thickness in the radial direction, namely without increasing the weight of a tire, as well as a tire using the steel cord for reinforcing a rubber article as a reinforcing material, especially a construction vehicle tire. Also provided is a steel cord for reinforcing rubber articles with a multi-twisted structure formed by twisting a plurality of sheath strands formed by twisting a plurality of wires around a core strand formed by twisting a plurality of wires, and the core strand being constituted of an at least three-layer-twisted structure formed by twisting core filaments and sheath filaments. The lowest tensile breaking strength of filament bs and the tensile breaking strength of steel cord Bc satisfy the relationship represented by the following formula: bs / Bc × 100 ≧ 0.65.
