ABSTRACT:
The present invention is a pre-pressurized in-line skate wheel which is capable of being pressurized at low levels and which further includes an integral bladder device having an annular tube and three bladder rods which are in fluid communication with respect to each other. The wheel is configured with a rigid polyurethane hub formed with a drop center and further having a pair of radially extending flanges with three pairs of axial openings. The hub is further formed with three radially projecting spokes. The tire body surrounds the bladder device and is constructed of a generally more resilient polyurethane which bonds to the hub, flanges and bladder. The method of manufacture utilizes blow molding techniques for the bladder device which includes a post vulcanization chlorine bath. The tire body is formed using liquid thermoset polyurethane poured into an open cast mold. The resulting wheel ensures the rider of a long lasting, light weight tire with exceptional shock absorption properties to therefore provide a smooth and comfortable ride.
