PURPOSE: A non-slip tire of a vehicle tire is provided to make a vehicle travel safely without slippage even in sudden braking or acceleration by increasing the contact friction power to the ground surface. CONSTITUTION: A rectangular pipe body(10) is attached with saw-tooth spikes(9) fitted in many grooves(2) of a disk(1). Protruded pieces(11',12') on the outer wall of the rectangular pipe body are fixed in recesses(3,3',4') of the grooves. Since the recesses of the grooves of the disk are inserted with the protruded pieces of the rectangular pipe body, the contact power of the saw-tooth spike of the top of the disk is improved.
