<p>A pneumatic tire comprising a carcass (82) including a plurality of ply cords (86) braided into an interlaced structure is disclosed. Each of the ply cords (86) follows a geodesic path from a first sidewall portion (94) to a second sidewall portion (100). A rubber layer (112) surrounds the carcass (86). Also, a method of forming a pneumatic tire (80) is disclosed. The method comprises: braiding a plurality of ply cords (86) into an interlaced structure using a braiding machine (12); moving a mandrel (28) axially relative to the braiding machine (12); while moving the mandrel (28) relative to the braiding machine (12), applying the braided ply cords (86) onto the mandrel (28) to form a carcass (82) including a crown portion (90), a first sidewall portion (94), and a second sidewall portion (100) connected with the first sidewall portion (94) by the crown portion (90); and varying a movement speed of the mandrel (28) such that each of the braided ply cords (86) follows a geodesic path from the first sidewall portion (94) to the second sidewall portion (100).</p> |
