The invention provides a bicycle tire with a steel wire layer, the bicycle tire comprises a tire body, the tire body comprises a tire body cord yarn, the steel wire layer and two tire beads, the two tire beads are symmetrically arranged on two sides of the tire body, and the steel wire layer is arranged in a tire crown area of the tire body; the tire body curtain yarn comprises a first curtain yarn and a second curtain yarn, the second curtain yarn is attached to the first curtain yarn, the steel wire layer is arranged on the second curtain yarn, and the two ends of the first curtain yarn and the two ends of the second curtain yarn bypass the tire bead and extend upwards in the radial direction. At least one layer of the first curtain yarn and the second curtain yarn crosses the equator plane, then continues to extend and is overlapped on the steel wire layer, at least two layers of the first curtain yarn and/or the second curtain yarn are overlapped on the radial outer side of the steel wire layer, and the outer sides of the edges of the two ends of the steel wire layer are wrapped by the overlapped first curtain yarn and/or the second curtain yarn. According to the technical scheme, the puncture-proof performance of the crown area of the bicycle tire can be improved, and steel wires at the two ends of the steel wire layer can be effectively prevented from warping or puncturing tread rubber.
