Abstract: Disclosed herein is an airless are which absorbs shock and holds pressure applied to the tire through an auxetic spoke buffer without using air pressure. The airless tire includes a cylindrical tread being in contact with the ground, an axle fixing section 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 fire when the spoke buffer is transformed by pressure or impact and fully returns to an original shape when pressure or impact is removed.

Abstract: Disclosed herein is a light emitting device for a tire, comprising: a light emitting pattern forming unit attached on a predetermined position of a tire sidewall, having at least one light emitting device in a regular array; a light emitting control unit for controlling on/off of each light emitting device in accordance with a predetermined light emitting pattern by a regular period; and a power supply unit for supplying a power to the light emitting control unit and the light emitting device.
