Abstract: The invention discloses a non-pneumatic tire, comprising a wheel hub; an annular belt located on the periphery of the wheel hub; spokes comprising a plurality of spokes circumferentially arranged between the annular belt and the wheel hub; each spoke being V-shaped, and the spoke comprising two inclined plates arranged at an angle and an arc-shaped apex corner area formed at the joint of the two inclined plates; a resistance part for limiting the deformation amount of the apex corner area to a deformation amount corresponding to the yield strength. According to the invention, plastic permanent deformation of spokes can be effectively avoided by adding resistance parts, and further the service life of non-pneumatic tires can be prolonged.
