The invention relates to a non-pneumatic tire, in particular to a non-pneumatic tire having an opening cavity. Aiming at such technical defects as limited inner cavity deformation space caused by closed structure, harder whole tire, weak elasticity, weak fit degree between a tire base and a hub and instable tire installation in a traditional non-pneumatic tire, the invention provides a non-pneumatic tire having an opening cavity. The non-pneumatic tire having the opening cavity comprises an annular tire body having an inner cavity, wherein the top of the annular tire body is a tire crown, and the bottom is a tire base. The non-pneumatic tire is characterized in that the inner cavity is the opening cavity with a downward opening; the tire crown is a closed end of the opening cavity; the tire base is an opening end of the opening cavity; tire feet are formed at the two ends of the opening end, and continuously extend in the annular direction of the tire body; and limiting parts fitting the hub are arranged on the tire feet. The shape of the inner cavity of the non-pneumatic tire is changed; the inner cavity is changed from the traditional closed structure to the opening cavity; the opening cavity can provide a wider deformation space to the tire; the elasticity of the tire is better; the fit degree of mounting the tire on the hub is good; and the installation is more stable.
