The invention discloses a tire with an improved tire bead structure. A pneumatic radial tire having a bead portion, the bead portion having a bead core provided therein; wherein the bead core is wrapped with bead core wrapping cloth; wherein the bead core wrap is formed of a reinforcing material; wherein the bead core wrap has an axially inner leg extending radially outward to a radial distance Li from the reference line XX '; wherein the wire XX'extends through the geometric center of the bead core; wherein the radial distance Li is equal to or greater than the bead radius as measured in the radial direction from the wire XX '. 带有改进胎圈结构的轮胎。具有胎圈部分的充气子午线轮胎，该胎圈部分中提供有胎圈芯；其中胎圈芯包绕有胎圈芯包布；其中胎圈芯包布由加强材料形成；其中胎圈芯包布具有轴向内腿部，该轴向内腿部径向向外延伸至自参考线XX'的径向距离Li；其中线XX'延伸通过胎圈芯的几何中心；其中如自线XX'在径向方向上测量的，径向距离Li等于或大于胎圈半径。
