Description
トレッドゴムのショルダー部はスクエア形状であって、
バッドレス部に突起を備え、前記トレッドゴム及び前記突起の抗張積は15000〜18000(MPa・%)であり、前記サイドウォールゴムの抗張積は10000〜12000(MPa・%)であることを特徴とする。
成形ドラムにインナーライナーを貼り付け、前記インナーライナーの外側にカーカスプライを貼り付け、ビードコアとビードフィラーを備えた一対のビードを前記カーカスプライの両端に載置し、前記カーカスプライの端部が各ビードを巻き上げるように前記カーカスプライの両端を折り返し、
前記カーカスプライの外側に、加硫後の抗張積が10000〜12000(MPa・%)であるサイドウォールゴムを貼り付け、
前記成形ドラムを拡径した後、前記カーカスプライのクラウン部に相当する位置の外側にベルト層及び加硫後の抗張積が15000〜18000(MPa・%)であるトレッドゴムを貼り付けて、生タイヤを成形し、
前記生タイヤのバットレス部に、加硫後の抗張積が15000〜18000(MPa・%)である帯状ゴム部材を貼り付けて環状突起部を形成し、前記生タイヤを金型で加硫成型することで製造される。
