A three-piece thread wound golf ball including a central solid core portion having increased diameter of 1.35-1.50 inch (34.3-38.1 mm) and specific gravity of 1.20-1.25, a thread-wound intermediate portion, having diameter of 1.54-1.60 inches, and an outer dimpled cover portion which construction provides desirable increased moment of inertia and spin characteristics for the ball. The resulting golf ball characteristics are such that when hit with a Driver, other woods or the longer iron club it performs like a distance two-piece golf ball, when hit with mid-iron clubs it performs like a two-piece Hi-spin golf ball and soft covered multi layered balls, and when it is struck with short iron clubs it performs much like a Balata wound golf ball.

Three-piece wound golf ball

A three-piece thread wound golf ball including a central solid core portion composed mainly of polybutadiene having a Shore D hardness of 55-75 and increased diameter (34.3-38.1 mm) and reduced specific gravity (1.20-1.25) compared to traditional three-piece wound golf balls. The solid core portion is wound with an elastomeric thread material to achieve a core and winding layer diameter of 39.1-40.6 mm. A dimpled cover portion formed of a thermoplastic material overlies the winding layer. The three-piece thread wound golf ball construction provides desirable increased moment of inertia and spin characteristics for the ball. The resulting golf ball characteristics are such that when hit with a driver, other woods or the longer iron clubs it performs like a distance two-piece golf ball; when hit with mid-iron clubs it performs like a two-piece Hi-spin or a soft covered multi layered golf ball; and when hit with short iron clubs it performs much like a Balata wound golf ball.

A three-piece wound golf ball having improved characteristics of moment of inertia, initial spin and total flight distance with minimal dispersion, the ball comprising:
