    Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire that improves durability of a carcass ply without causing other problems such as occurrence of disconnection in a manufacturing process.SOLUTION: There is provided a pneumatic tire of which skeleton is at least one carcass ply prepared by coating the rubber to a steel cord. The steel cord is the twisted cord of the cord diameter ≤0.85 mm prepared by twisting a plurality of steel filaments into 1×L structure or M+N structure. A wrap filament that wraps around a plurality of steel filaments to binds the plurality of steel filaments is excluded from the steel cord, and the spacing between the steel cords adjacent each other at the end part of the carcass ply is in the range of 0.15-0.60 mm.

    Abstract: PROBLEM TO BE SOLVED: To provide a rubber composition which, when used for the tread rubber of a tire, can improve both the initial gripping performance and the travelling stability of the tire more than those of the conventional one, and provide a pneumatic tire using the rubber composition for the tread rubber.
    SOLUTION: For the tread rubber of the tire there is used the rubber composition characterized by incorporating, based on 100 pts.mass of a rubber component, 10-60 pts.mass of at least one hydrogenated petroleum resin having a softening point of ≥120°C, obtained by partially or wholly hydrogenating a petroleum resin consisting of 5C components and/or 9C components. The rubber composition is further incorporated with 5-60 parts by mass of at least one resin selected from 9C resins which have a softening point of ≥140°C and ≤190°C and contain indene, based on 100 pts.mass of the rubber component.
