Abstract

　ビードワイヤの断面形状及びその配置の適正化を図ることにより、ビードコア全体としての回転剛性を大きくしてカーカス引き抜けを抑制し、もってビード部の耐久性の向上を図り得る空気入りタイヤを提供する。 　空気入りタイヤは、一対のビード部１と、一対のサイドウォール部と、両サイドウォール部間に跨って延びるトレッド部とを具え、これら各部に亘ってトロイド状に延び、両端部をビードコア２の周りに折り返してなるカーカス４を有する。ビードワイヤ３は、タイヤ幅方向断面にて、平行四辺形断面を具え、第一鋭角隅部７ａは、第二鋭角隅部７ｂのタイヤ幅方向外側であってタイヤ径方向内側にあり、第一鈍角隅部９ａは、第一鋭角隅部７ａのタイヤ幅方向内側であってタイヤ径方向外側にあり、第二鈍角部９ｂは、第一鋭角隅部７ａのタイヤ幅方向内側にあり、かつタイヤ径方向において第一鋭角隅部７ａと同一線上の位置又はこれより内側にある。
