The invention discloses a double-pressure tire. The double-pressure tire is characterized by comprising an outer tire, a middle layer and an inner tire, wherein the middle layer is located between the outer tire and the inner tire, so that the outer tire, the middle layer and the inner tire are sequentially wrapped. Air faucets 4 and 5 corresponding to the outer tire and the inner tire are arranged between the outer tire and the inner tire, so as to form dual-layer pressure. The middle layer is made of rubber; the thickness is 1-5 centimeters; and relatively short nails can be prevented from puncturing the inner tire. Two air faucets are arranged on the improved double-pressure tire and correspond to double pressure (the inner tire and the outer tire are aerated); the inner tire is firstly aerated in aeration, and is fully aerated; the outer tire is aerated; if the outer tire is flat in travel, the tire can normally drive due to the action of the middle layer and the inner tire; even if the outer tire is low in air pressure, the outer tire can also be supported through the expansive action of the inner tire on the middle tire, so that the outer tire does not deform; the middle tire is 1-5 centimeters in thickness; and the relatively short nails can be prevented from puncturing the inner tire.
