The invention relates to a double-purpose tire. The double-purpose tire comprises a road wheel and a rail wheel, wherein the outer diameter of the rail wheel is smaller than that of the road wheel; the road wheel comprises a wheel hub and a tire body matched with the wheel hub, wherein the wheel hub comprises a wheel rim for mounting the tire body, and wheel spokes for supporting the wheel rim; the rail wheel is connected to the wheel hub, and a running surface in contact with rails is formed on the wheel surface of the rail wheel. According to the double-purpose tire, the rail wheel is mounted on the wheel hub of the road wheel, when screw holes are formed in the wheel hub, the rail wheel can be mounted, the whole wheel structure is very simple, and the double-purpose tire is convenient to manufacture; the normal running of a vehicle on different road surfaces can be guaranteed through the road wheels, and the purpose that the vehicle can run on a specific rail can be achieved through the rail wheels; compared with the conventional manner that a rail contact surface is directly formed on a steel ring, the double-purpose tire realizes the contact of the rail wheel and the rail, so that the wheel hub (namely the steel ring) can be better protected, the road wheel can be further protected, and the service life of the vehicle wheel can be prolonged.
