The tire is then inflated thus holding the now solid rim or track in position. Each section includes a curved base and a ground-surface engaging projection extending therefrom. The curved base includes a planar plate portion at one end and a trailing jaw portion at the other end. The plate portion of one section engages the jaw portion of the next adjacent section and the jaws are then closed over the plate and a fastener such as a rivet or the like, is placed through the jaws and through the plate thus forming the rigid connection. There is room provided in the engagement of the plate with the jaws to adjust the sections before fastening same so that the desired diameter of the finished rim or track may be obtained. | |
