[0003] Common tires are usually composed of tread, shoulder, sidewall, bead and cushion layer. The tread is the part of the tire that contacts the ground most closely, the shoulder is the part that connects the crown and the sidewall, and also plays a supporting and protective role, the sidewall is the most fragile part of the tire, and plays a supporting and damping function, the bead is the part of the tire that contacts the rim, and plays a fixing and sealing role, the cushion layer is located between the tread and the tire body, and wraps around the tire body.

[0004] Traditional tires, whether with or without inner tube, the part directly contacting the ground is the tread layer of the outer tire. Currently, the tread of the tire is cured as one body with the belt layer, tire body and other parts through molding, vulcanization and other processes. When the tire tread is worn out, most of them need to be replaced with new tires, and some need to be refurbished by a refurbishing factory. However, this method requires the replacement of the entire tire when the tread of the ordinary tire is worn out, and the old tire body needs to be scrapped, which not only wastes resources and energy, but also causes serious environmental pollution. In addition, the tires that can be refurbished need to be taken to a specific refurbishing factory for refurbishment, which requires processes such as grinding, tread attachment and vulcanization on the old tire body, and the cost is high. Therefore, an energy-saving and environmentally-friendly tire with convenient tread replacement is proposed. SUMMARY
