Belt reinforcing structure for a pneumatic tire

摘要

A pneumatic tire has a belt reinforcing structure comprising a folded belt ply and a spirally wound structure extending transversely between the folded edges of folded portions of the folded belt ply. No cut belts are used in the assembly. In an illustrated embodiment, both the folded belt ply and the spirally wound ply are reinforced with aramid cords. Also, a plurality of spirally wound plies can be used.
