<p>A tire chain comprises: a ground part bound to a ground surface of a tire so as to prevent the slipping of the tire; a first coupling part provided with a plurality of units having elastic force which are extended from one end of the ground part; and a second coupling part extending from the other end of the ground part and coupled to the first coupling part so as to allow the ground part to come into close contact with the ground surface of the tire, wherein the ground part comprises: a plurality of first ground members inserted into grooves formed in a circumferential direction on the ground surface of the tire so as to prevent the ground part from slipping in a horizontal direction when the tire is rotated; and a plurality of second ground members inserted into grooves formed in a vertical direction of the grooves that are formed in the circumferential direction so as to prevent the ground part from slipping in a circumferential direction when the tire is rotated.</p> |
