Abstract: A pneumatic tire is described which includes a tread, a carcass and a belt structure interposed between the carcass and the tread. The belt structure includes a pair of working belts, wherein the angle of the working belts range from about 15 degrees to about 30 degrees, wherein the belt structure further includes a zigzag belt structure located between the working belts. The zigzag belt structure is formed of at least two layers of cords interwoven together from a strip of rubber reinforced with one or more cords, wherein the strip forming the zigzag belt structure is layed up in a first zigzag winding extending from a first lateral belt edge to a second lateral belt edge in a zigzag wavelength having a first amplitude W1 followed by a second amplitude W2, and a second zigzag winding formed of a zigzag wavelength having a first amplitude W2 followed by a second amplitude W1.

Abstract: A pneumatic tire has a carcass and a belt reinforcing structure. The belt reinforcing structure includes a sine wave belt layer having a first and second axially outer edge, wherein the belt is laid up in a sine wave pattern which extends from a first edge to a second edge. Preferably the belt is laid up in strips of reinforced rubber having two or more cords, wherein the reinforcement cords are made of a high elongation cable.

Abstract: A pneumatic tire has a carcass and a belt reinforcing structure. The belt reinforcing structure includes a first zigzag belt layer having a first amplitude and a first wavelength and a second zigzag belt layer having a second amplitude and a second wavelength. The first wavelength of the first zigzag layer is out of phase with the second wavelength of the second zigzag layer.

Abstract: A pneumatic tire is described which includes a tread, a carcass and a belt structure interposed between the carcass and the tread. The belt structure includes a pair of working belts, wherein the angle of the working belts range from about 15 degrees to about 30 degrees, wherein the belt structure further includes a zigzag belt structure located radially inward of the working belts. The zigzag belt structure is formed of at least two layers of cords interwoven together from a strip of rubber reinforced with one or more cords, wherein the strip forming the zigzag belt structure is layed up in a first zigzag winding extending from a first lateral belt edge to a second lateral belt edge in a zigzag wavelength having a first amplitude W1 followed by a second amplitude W2, and a second zigzag winding formed of a zigzag wavelength having a first amplitude W2 followed by a second amplitude W1.

Abstract: A pneumatic tire for use on trucks, the tire comprising: a tread which includes a belt reinforcement structure, the belt structure including a pair of working belts, wherein the angle of the working belts range from about 16 degrees to about 30 degrees, wherein a low angle belt is positioned preferably between of the working belts, wherein the angle of the low angle belt is less than 5 degrees. The working belts are extensible, and preferably made of high elongation wire.

Abstract: A pneumatic tire includes a pair of parallel annular bead portions, at least one carcass ply reinforcing structure wrapped around the beads, a tread disposed radially outward of the carcass ply, a belt reinforcing structure disposed radially outward of the carcass ply reinforcing structure and radially inward of the tread in a crown area of the tire, and a layer of cords having an alternating straight/curled construction for improving performance characteristics of the pneumatic tire.
