Abstract:

A pneumatic tire includes a carcass with a plurality of ply cords braided into an interlaced structure. Each of the ply cords follows a geodesic path from a first sidewall portion across a crown portion to a second sidewall portion. The pneumatic tire also includes a rubber layer encasing the carcass and including a tread adjacent the crown portion. The pneumatic tire does not include any beads because the plurality of carcass plies is folded onto itself at each of the first and second sidewall portions. Thus, the benefits of geodesic plies and braided ply construction are achieved by the pneumatic tire.
