The invention discloses an E-TPU (expanded thermoplastic polyurethane) tire and a manufacturing method thereof, and in particular relates to an E-TPU tire which is used in low-velocity cars, such as tricycles, bicycles, sport cars, scooters, toy cars, and disabled cars, or no-motor cars or motor-cars, and a manufacturing method of the tire. The tire is characterized in that a circular-ring-shaped tire body is positioned among an outer protection layer, a lining and an inner ring protection layer; the tire body is wrapped with the outer protection layer, the lining and the inner ring protection layer in a non-continuous manner; the tire body is formed by bonding a plurality of E-TPU foamed elastic grains by an adhesive or by adopting a surface hot melting or vapor mold forming method; the outer protection layer, the lining and the inner ring protection layer are bonded with the tire body by adopting an adhesive or in a heating manner; the outer protection layer, the lining and the inner ring protection layer are made from rubber or rubber compounds or rubber compositions or polyurethane elastomers. The tire disclosed by the invention is free of air inflation, and has the characteristics of being capable of resisting bursting and resisting impaling, free of maintenance, light in weight, good in elasticity, good in friction force with the ground, low in manufacture cost, long in service life and the like.
