<p>A pneumatic tire containing a tread (500), a carcass (210) having at least one belt ply (230) disposed below the tread, and a cap ply (300) located between the carcass and the tread. The cap ply comprises at least one layer of an open construction leno weave tape having a pair of warp yarns (311, 313) in the longitudinal direction and a weft yarn (312) in the weft direction. The pair of warp yams comprises a first warp yarn (311) and a second warp yarn (312), where the second warp yarn has a force of elongation of between about 1 and 40% the force of elongation of the first warp yarn, where the second warp yarn is in tension, and where the second warp yarn has an elongation at break of greater than 2%. The leno weave tape is disposed helically in a flat pattern around the circumference of the carcass in the area of the belt ply. A method of making a pneumatic tire is also disclosed.</p> |
