A non-inflatable tire having a tread of a comfortable elastic structure, comprising an inner ring (1), a radial plate (2), supporting plates (3), and an outer ring (4), which are molded integrally. The inner ring (1) and the outer ring (4) are of a concentric structure. The radial plate (2) is connected to the outer ring (4) and the inner ring (1) in a common central axis plane of the outer ring (4) and the inner ring (1). The supporting plates (3), connected to the outer ring (4) and the inner ring (1), are disposed on left and right sides of the radial plate (2), respectively. The supporting plates (3) on the left and right sides of the radial plate (2) are disposed oppositely. The supporting plates (3) are vertically connected to the radial plate (2). Included angles of 15-75° are formed between the supporting plates (3) and inner ring radial planes formed by connecting lines between the supporting plates (3) and the inner ring (1). The outer ring (4) is provided with an annular middle groove (41). The outer ring (4) is partitioned into a left outer ring and a right outer ring by means of the annular middle groove (41). The bottom of the annular middle groove (41) protrudes from the inner surface of a tread (6) and is connected to the radial plate (2). The left outer ring and the right outer ring are provided with at least one outer ring longitudinal groove (42) parallel to the annular middle groove (41), separately. The tire has a relatively good road holding performance, slip resistance and comfort. |
