A safety wheel for a vehicle includes a rim having a body and a protrusion extending outward from an outer circumference of the body, and having a fastening groove; a first rubber layer wrapped on the protrusion of the rim; an air-filled tube disposed on the first rubber layer, and having a hollow body filled with compressed air therein; an outermost second rubber layer wrapped on the rim protrusion, the first rubber layer and the air-filled tube; and a rubber sheath wrapped on the rim protrusion, the first rubber layer, the air-filled tube and the second rubber layer. The safety wheel maintains pressure to support the weight of the vehicle, and even if the tire is blown out, prevents the vehicle from rocking and overturning due to inclination, as well as affords stability so that the vehicle can travel for a predetermined distance.
