A pneumatic rubber tire (1) is provided having inner and outer air retention quasi envelopes which individually substantially envelop the tire air chamber (2) and which are comprised of a first inner quasi envelope as an integral innerliner (7) and a secon...

The rubber composition of the present invention is used for producing an inner liner of a pneumatic tire, and is obtained by compounding a rubber component and a layered or plate-like mineral. The layered or plate-like mineral has an aspect ratio of 3 or m...

A pneumatic tyre comprising a carcass (6) comprising a ply (9) of cords (10) defining the innermost reinforcing cord layer extending between bead portions (4), and an airtight layer disposed inside the cords (10) of the carcass ply along the inner surface ...

A pneumatic radial tire which can run in a flat tire condition comprising: a side reinforcing layer disposed on a carcass layer of the side region and having a generally crescent sectional shape; and a belt layer composed of a belt ply in which metal wire ...

In a tubeless tire, an air blocking layer formed from ethylene-vinyl alcohol copolymer for air-tightly covering an inner surface of a tire body is integrally provided in the tire body. Therefore, air leaking in the tire can effectively be prevented to do a...

A thermoplastic elastomer composition of a structure of a thermoplastic resin (A) in which a rubber composition (B) is dispersed, where the stress at the time of 2.5% elongation of the stress-strain curve of the thermoplastic elastomer composition is 0.1 t...
