Abstract: A pneumatic tire which comprises a belt disposed radially outside a carcass and inside a tread and having opposite axial edges, the belt comprising a cord continuously wound around the carcass while running zigzag between the edges of the belt to defining cord segments extending between the edges of the belt, the cord segments including first cord segments and second cord segments, the first cord segments laid substantially parallel with each other, and the second cord segments laid substantially parallel with each other and crosswise to the first cord segments.

Abstract: An iron type golf club head comprising a composite material of light metal or synthetic resin containing silicon carbide whiskers at 2 to 80% by volume and occupying 20% or more by volume of the body of the club head. The club head can be 10 to 60% lighter than a club head made entirely of steel with the same configuration and size, while the moment of inertia is approximately the same. Weight metal inserts having a specific gravity greater than steel can also be embedded in the club head.
