Self-healing tire

A self-healing tire for vehicles, comprising:

• a rim;
• a tire casing installed around the rim;
• an inflated inner tube disposed between the rim and the tire casing;
• a partition structure disposed between the tire casing and the inflated inner tube, wherein the partition structure withstands the high pressure of the inflated inner tube and separates the tire casing and the inflated inner tube to form a space for a sealant storing layer;
• and
• a liquid sealant injected into the sealant storing layer and stored therein,
• wherein an outer surface of the inflated inner tube contacts and presses an inner surface of the tire casing and the partition structure, and the inflated inner tube keeps the tire casing in shape to withstand the weight of the vehicle.
