Abstract: A rubber-covered belt ply forms a belt layer. At least a majority of metal wires in the ply exist as metal wire bundles in which a plurality of metal wires of circular cross-sections and substantially equal wire diameters are aligned in parallel without being twisted together, the metal wire bundles being aligned planarly and in parallel with intervals between the metal wire bundles in a transverse direction. At least one layer, which is a cap layer in which organic fibers are covered with rubber and/or a reinforcing layer which is formed of rubber or whose main component is rubber, is disposed between the belt layer and a tread.

Abstract: PROBLEM TO BE SOLVED: To provide a tire particle aggregate capable of sealing a damaged part more surely, and recovering an inner pressure required for traveling after damage at an early stage.
SOLUTION: This tire particle aggregate 100 is an aggregate of a tire 1 and a plurality of hollow particles 4. A side rubber 9 constituting a side wall SW comprises an inner side rubber 9a positioned at least on the inner side of a tread width direction, and an outer side rubber 9b positioned on the outer side of the tread width direction. The outer side rubber 9b has a tangent loss α (tanδ) in 1% load of 0.05-0.12 and a tangent loss β (tanδ) in 3% load of 0.35-0.50. The hollow particle 4 is made of resin continuous phases and independent bubbles having an approximately spherical shape, and is expanded by reaching to a re-expansion starting temperature (Ts2) when the inner pressure of a tire air space 3 is lowered.

Abstract: PURPOSE: To improve both the steering performance and the riding comfort performance by taking an organic fiber, the intermediate ductility of which is specified in the case of a specified atmosphere temperature and designated load as a cord for forming an organic fiber belt. CONSTITUTION: If the intermediate ductility at an atmosphere temperature of 50 deg.C with load of 0.3g/D(gram/denier) of an organic fiber cord for forming an organic fiber belt 5 is 0.4% or more, the steering performance can be kept at high level as tire performance. That is, when a tire 1 travels, corresponding to the temperature and the load which the cord for forming the organic fiber belt 5 receives, if the intermediate ductility is 0.4% or less, the elastic modulus of the cord is high and the rigidity of the tire 1 is made higher. If the intermediate ductility of the cord at an atmosphere temperature of 165 deg.C with load of 1.0g/(gram/denier) is from 1.2% to 2.0%, the riding comfort performance can be kept at a high level as tire performance. Further, both the above performances can be improved with good balance by setting the internal pressure high when the tire 1 is subjected to PCT processing.
