To provide a method for producing a tire capable of more appropriately correcting the weight unbalance of individual tires having sound dampers on the tire inner surfaces by using the sound damper.SOLUTION: The position of a light point K of the weight unbalance of a vulcanized tire 1 and a weight unbalance amount Bt are detected. A weight unbalance amount Bs of a sound damper 8 generated by an intermittent part 8i is determined based on the detected weight unbalance amount Bt of the tire 1 when the sound damper 8 is installed with at least one intermittent part 8i so as to extend in the tire circumferential direction with respect to a tire inner surface 7 of the tire 1. The sound damper 8 with a specification for generating the determined weight unbalance amount Bs is installed by joining to the tire inner surface 7 of the tire 1. At this time, the position of a light point P of the weight unbalance of the sound damper 8 is arranged in a range of ±30° in the tire circumferential direction centering on a position opposed to the position of the detected light point K of the tire 1.SELECTED DRAWING: Figure 1
【課題】タイヤ内面に制音体を備えた個々のタイヤの重量アンバランスを、制音体を用いて一段と適切に是正できるタイヤの製造方法を提供する。【解決手段】加硫されたタイヤ1の重量アンバランスの軽点Kの位置および重量アンバランス量Btを検知し、このタイヤ1のタイヤ内面7に対して、制音体8を少なくとも1か所の間欠部8iを有してタイヤ周方向に延在させて設置した場合に間欠部8iにより生じる制音体8の重量アンバランス量Bsを、検知したタイヤ1の重量アンバランス量Btに基づいて決定し、この決定した重量アンバランス量Bsを生じさせる仕様の制音体8をこのタイヤ1のタイヤ内面7に接合して設置し、その際に、この制音体8の重量アンバランスの軽点Pの位置を、検知したタイヤ1の軽点Kの位置に対向する位置を中心とするタイヤ周方向±30°の範囲に配置する。【選択図】図1
