Abstract
A non-pneumatic tire includes a tread layer and a spoke layer including an inner cylinder and several spoke assemblies. The tread layer is annular and has a maximum outer diameter of the non-pneumatic tire and is adapted to be in contact with a ground. The spoke assemblies extend in a radial direction of the non-pneumatic tire and are arranged around an axial core of the non-pneumatic tire. An end of each spoke assembly is connected to the inner cylinder, and another end thereof is connected to the tread layer. Each spoke assembly includes a straight spoke, a bending spoke, and a connecting rib. Each bending spoke includes a first segment and a second segment, which are not connected in a straight line. Each connecting rib has a first end connected to the straight spoke and a second end opposite to the first end and connected to the bending spoke. When the non-pneumatic tire bears a weight and is squeezed, the spoke assemblies do not get in contact with one another.
