摘要：
A bead portion of a tire has a short fiber reinforcing rubber layer extending along a side surface of a rubber bead apex from a bead core to a height position which is lower than the radially outer end of the bead apex rubber. The short fiber reinforcing rubber layer has short fibers compounded in an amount of 10 to 30 parts by weight with respect to 100 parts by weight of the rubber, and the short fibers are oriented in the tire circumferential direction.
