The invention relates to an automobile tyre protection device, and especially relates to a protection device, which is used to protect the tyres when an automobile goes through steps. The protection device comprises a rubber body (1), wherein the cross section of the rubber body (1) is in a major arc shape, and the rubber body (1) bends to the opening of the cross section. The rubber body (1) comprises a top part (11) and two side parts (12). The joints between the outer surface of the top part (11) and the outer surfaces of two side parts are provided with a chamfering surface (13) respectively. The extension cord of the chamfering of the cross section form an inclined angle (a) with the symmetrical surface of the rubber body (1), wherein the (a) is not more than 60 degrees and is not less than 20 degrees; and the chambering surfaces (13) are both provided with a ripple structure (2). The inner surface of the top part (11) of the cross section is linear, the angle (b) between the inner surfaces of the side parts (12) and the inner surface of the top part (11) is an obtuse angle. The provided automobile tyre protection device has the advantages of low cost, simpleness, and practicality, can effectively protect the automobile tyres, can be used to protect the automobiles when the automobiles go through steps, and is the necessary equipment for self-driving travel.
