1. A tire surface managing method, comprising:
emitting detecting light to a target object on a surface of a tire;
receiving reflected detecting light from the target object and reflected detecting light from the surface adjacent to the target object;
determining whether the target object protrudes from the surface according to a distance calculated according to the reflected detecting light from the target object and a distance calculated according to the reflected detecting light from the surface adjacent to the target object;
determining 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;
receiving the reflected detecting light from the surface to calculate a width of the hole on the tire; and
activating a protection mechanism for a vehicle comprising the tire if the width is larger than a width threshold.
