Abstract: High elastic non-pneumatic tires belong to tires. The tire has a carcass, a plurality of cavities are arranged in the carcass, and a tire crown is provided with tire patterns; The part contacting with the rim is a tire toe, and the cavity of the cavity is parallel to the tire toe; There are spiral concave-convex grooves in the cavity, anti-skid grooves on the contact surface between the carcass and the rim, and the cross section of the spiral concave-convex grooves in the cavity is trapezoidal. Non-pneumatic tires are directly made of rubber, which saves raw materials such as curtain cloth, steel wire and air nozzle. And the structure is simple and reasonable, and the manufacturing process is simple. Using this kind of tire avoids the trouble of puncture and puncture.
