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: The present invention is directed to a pneumatic tire 1, in particular a low aspect ratio super single truck tire 1. In accordance with the invention, the tire has a crown reinforcing structure with a first breaker 9 between a carcass ply 3 and a tread 5, as well as four further breakers 11, 13, 15, 17 comprising at least one pair of working breakers between the first breaker 9 and the tread 5, wherein the first breaker 9 is a split breaker comprising two circumferential strips 9 essentially adjacent to the shoulders of the tire, each strip having an axial width comprised between 50% and 70% of the half tread width.

Abstract: A pneumatic low aspect ratio truck has a crown reinforcing structure 7, the crown reinforcing structure 7 has a first steel belt ply 9 between the at least one carcass ply 3 and the tread 5, a second steel belt ply 11 between the first belt ply 9 and the tread 5, such that the first and the second belt plies 9, 11 form a first pair of adjacent working belts. A third steel belt ply 13 between the second steel belt ply 11 and the tread 5 and a fourth steel belt ply 15 between the third steel belt ply 13 and the tread 5 such that the third and the fourth belt plies 13, 15 form a second pair of adjacent working belts. The crown reinforcing structure 7 additionally has at least one circumferential steel strip 17 between the second and the third belt plies 11, 13, wherein the at least one steel strip 17 is positioned essentially radially underneath a shoulder groove location 19.

Abstract: The present invention is directed to a pneumatic tire 1, in particular a low aspect ratio super single truck tire 1, comprising at least one pair of parallel annular beads, at least one carcass ply 3 wrapped around said beads, a tread 5, first and second sidewalls disposed between said tread 5 and one of said at least one pair of beads, and a crown reinforcing structure disposed between said at least one carcass ply 3 and said tread 5 in a crown area of said tire 1. In accordance with the invention said crown reinforcing structure comprises a first breaker 9 between the at least one carcass ply 3 and the tread 5, as well as four further breakers 11, 13, 15, 17 comprising at least one pair of working breakers between the first breaker 9 and the tread 5, wherein the first breaker 9 is a split breaker comprising two circumferential strips 9 essentially adjacent to the shoulders of the tire, each strip having an axial width comprised between 50% and 70% of the half tread width.

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.

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.
