Claim 1:
2. A tire surface managing system, comprising:
a light source, configured to emit detecting light to a target object on a surface of a tire;
a light sensor, configured to receive reflected detecting light from the target object and reflected detecting light from the surface adjacent to the target tire;
a calculating unit, configured to determine whether the target object forms a hole on the surface according to the distance calculated according to the reflected detecting light from the target object and the distance calculated according to the reflected detecting light from the surface adjacent to the target object; and
a control unit;
wherein the calculating unit further calculates a width of the hole according to the reflected detecting light from the surface, and the control unit activates a protection mechanism for a vehicle comprising the tire if the width is larger than a width threshold.
