A pneumatic tire comprising a tread (25), a carcass (31) and a belt structure (40) interposed between the carcass (31) and the tread (25) is disclosed. The belt structure (40) includes a zigzag belt structure (39) 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 (39) is laid up in a winding pattern in accordance with the following formula: for i =1 through L, the i th winding cycle is: [W L -(i- 1 )Wi] x N for each revolution, wherein L is the number of different amplitudes W1 , .... W L used to define the zigzag belt structure (39) and L ¥ 2, and N is the number of zigzag cycles per revolution.
