A grooved-type polyurethane hand cart tire being free of tire burst includes a hand cart tire hub, a hand cart tire inner ring, an annular radial plate, a hand cart tire tread and more than two first supporting plates and second supporting plates. The hand cart tire inner ring is arranged outside the hand cart tire hub. The cyclic radial plate sleeves outside the hand cart tire inner ring and is arranged vertically to the hand cart tire inner ring. The first supporting plates are uniformly arranged at one side of the cyclic radial plate in an inclined radiation manner and the second supporting plates are uniformly arranged at the other side of the cyclic radial plate in an inclined radiation manner. The upper ends and the lower ends of the first supporting plates and the second supporting plates are respectively connected to the hand cart tire inner ring and the hand cart tire tread. The inner wall of the hand cart tire inner ring is connected to the hand cart tire inner ring. A groove is arranged between outer wall of the cyclic radial plate and the hand cart tire tread. By means of the improvement, the grooved-type polyurethane hand cart tire shows proper hardness and deflection degree in test and the technical indexes, such as supporting property, comfortability, operability and bearing capacity and the like, are almost same as those of a pneumatic tire.
