The invention relates to the technical field of motorcycle tires, in particular to a run-flat tire for motorcycles and electric vehicles. The tire comprises a tire body, an air-retaining layer positioned on the inner side of the tire body, cord fabric layers positioned on the outer side of the air-retaining layer, a buffer layer positioned on the radial outer sides of the cord fabric layers, and areinforcing layer positioned on the inner side of the air-retaining layer; the tire body comprises a tire crown part, tire shoulder parts located on two sides of the tire crown part, tire side partslocated under the two tire shoulder parts and tire lip parts, and both ends of the cord fabric layers bypass the tire lip parts respectively and are turned up outwards; the tire lip parts are providedwith a steel wire ring; the reinforcing layer is arranged on the inner side of the air-retaining layer near the tire shoulder parts, extends towards the tire crown part and the tire side parts respectively and is gradually reduced in thickness; and the hardness of a rubber material of the reinforcing layer is greater than that of a sidewall rubber. According to the invention, the motorcycle tirecan still run continuously for 20km at a speed of 30km/h in a zero-air-pressure state, and meanwhile, the air tightness of the motorcycle tire is protected from being damaged until a next maintenancepoint is found.
