PROBLEM TO BE SOLVED: To provide a hollow tire, securing moderate cushioning property, decreasing the rubber volume used in forming the tire, and reducing the rotational resistance value during application of load. SOLUTION: In this hollow tire, right and left rim seating parts 29, right and left recessed parts 28, right and left side wall parts 27k, and a tread part 26 are integrally formed along the meridian direction of the tire, and a cavity part 30A is provided inside. The sectional form of the tire grounding side of the cavity part 30A is angled or shaped like a circular-arc seen from the center axis of the tire. The opposite surfaces of the right and left rim seating parts 29 are abutted on each other, and the rim seating part 29 is fitted to a rim part 23 of a wheel to fix the hollow tire 20A to a wheel part 22.
