摘要： An improved tire 200 having precured tire tread 10 for mounting to an unvulcanized or a vulcanized tire casing 100 is disclosed. The improved precured tread 10 has a pair of circumferentially continuous projections 60. One projection 60 extends axially outwardly from each of the lateral surfaces 40,50 of the tread. The rejection 60 provides a means for air tightly sealing the tread casing assembly at the lateral surfaces 40, 50 during the vulcanization of the tread 10 to the casing 100. The method of assembly includes placing the tread 10 and casing 100 in a smooth mold, closing the mold inflating a bladder expanding the casing 100 into the tread 10, the tread 10 correspondingly expands effecting an air tight sealing of the tread 10 and the mold at the annular projections 60 of the tread 10, applying heat and pressure causing a uniform flow of unvulcanized material radially outwardly along the tread edges. This invention provides uniform pressure distribution on the tire casing during curing. In this way belt package distortion is greatly minimized or eliminated. In another embodiment, a precured inner liner eliminates the need for an inflatable bladder.
