Latest Patents

Hirano’s listed patent, “Pneumatic Tire,” describes a tire with a tread, sidewalls, bead portions, a carcass, and a belt. The carcass uses rubber-coated organic-fiber cords arranged in substantially radial planes, while the belt uses rubber-coated metal cords positioned at relatively small angles to the tire’s equatorial line.

The invention adds a reinforcing layer inside and in close contact with the folded edge of the belt’s metal-cord layer. This layer extends at least 7% of the belt’s overall width from the belt’s folded position. Its organic-fiber cords run parallel to one another at angles of 0 to 40 degrees relative to the tire’s equatorial line. Hirano is credited with 1 patent.
