摘要： An improved bicycle tire which can be folded for storage and transportation while maintaining the same running properties as a conventional tire. A plurality of bead cores made of a cord tensile member embedded in the bead section of the tire are provided by winding three to five turns of a cord tensile member having a low elongation ratio and high strength and which has been twisted one to two turns/10 cm in such a manner that the start and finish ends of the bead core overlap one another by 60 to 150 mm. The bead core preferably has a cut elongation of 5% or less and the strength of 300 kg/core.
