A support device (2000) with two support brackets is provided on the inside of tire (10). The bracket is assembled from a row of curved supports (20) with compression springs (208) in between, two flexible packing rings (30) and two interlocking coupling tubes (205, 206). A tire has two inner lips (101) protruding from opposite side walls and provided with a number of plug holes (104) and positioning holes (103). A supplementary support device supported on the inside of the tire between the inner lips comprises two support brackets, each bracket comprising a number of curved supports connected in series, a number of compression springs between the supports and two flexible packing rings secured to the inner lips and brackets. The packing ring has a corrugated inner periphery cooperating with the corrugated lower side walls (102) of the inner lips. The support has a downwards-facing flange (202) on one side, acting as a stop for the packing ring. A screw bolt is provided at one end of the support and an eyelet is provided at the other end, the eyelet providing a hole for receiving the bolt at the end of an adjoining support. Plug and positioning bars (205a, 206a) are pressed into the plug and positioning holes. A coupling tube (205) associated with one support contains holes (205c) into which hooks (206c) on a coupling tube (206) associated with another support can be selectively fitted. Compression springs (208) are mounted inside the coupling tubes. |
