Disclosed herein is an airless tire which absorbs shock and holds pressure applied to the tire through an auxetic spoke buffer (30) without using air pressure. The airless tire includes a cylindrical tread (10) being in contact with the ground, an axle fixing section (20) having a smaller circumference than the tread and disposed inside the tread, and an auxetic spoke buffer connecting the tread and the axle fixing section and providing a buffering function. Accordingly, the airless tire is transformed only to an extent to properly function as a tire when the spoke buffer is transformed by pressure or impact and fully returns to an original shape when pressure or impact is removed. |
