A tire support system comprising: a plurality of support sectors (101; 701), each support sector (101; 701) having a first end including an overlap extension (102; 702) extending therefrom and a second end including an overlap extension (103; 703) extending therefrom, each overlap extension (102, 103; 702; 703) including a terminal flange (104, 105; 704, 705) and a terminal flange engagement region (106, 107; 706, 707), the terminal flange engagement region (106, 107; 706, 707) having a surface contoured to conform with the at least one terminal flange (104, 105; 704, 705) on at least one other support sector (101; 701) in the plurality of support sectors (101; 701), whereby the respective overlap extensions (102, 103; 702, 703) of adjacent sectors (101; 701) overlap one another and the plurality of connected sectors (101; 701) when connected are configured to form an annular support ring; characterized in that the overlap extension (103; 703) of the second end includes in the terminal flange engagement region (106, 107; 706, 707) at least one hole (111; 711; 811) that extends completely therethrough and is countersunk on the radially inward side of the overlap extension (103; 703) of the second end, the overlap extension (102; 702) of the first end includes in the terminal flange (104, 105; 704, 705) at least one hole (111; 711; 812) extending at least partially into it, and the at least one hole (111; 711; 811) of the overlap extension (103; 703) of the second end and the at least one hole (111; 711; 812) of the overlap extension (102; 702) of the first end are adapted to align with one another to create a single path or channel in a radial direction for receiving a fastener that helps secure the support sectors (101; 701) together. a plurality of support sectors (101; 701), each support sector (101; 701) having a first end including an overlap extension (102; 702) extending therefrom and a second end including an overlap extension (103; 703) extending therefrom, each overlap extension (102, 103; 702; 703) including a terminal flange (104, 105; 704, 705) and a terminal flange engagement region (106, 107; 706, 707), the terminal flange engagement region (106, 107; 706, 707) having a surface contoured to conform with the at least one terminal flange (104, 105; 704, 705) on at least one other support sector (101; 701) in the plurality of support sectors (101; 701), whereby the respective overlap extensions (102, 103; 702, 703) of adjacent sectors (101; 701) overlap one another and the plurality of connected sectors (101; 701) when connected are configured to form an annular support ring; characterized in that the overlap extension (103; 703) of the second end includes in the terminal flange engagement region (106, 107; 706, 707) at least one hole (111; 711; 811) that extends completely therethrough and is countersunk on the radially inward side of the overlap extension (103; 703) of the second end, the overlap extension (102; 702) of the first end includes in the terminal flange (104, 105; 704, 705) at least one hole (111; 711; 812) extending at least partially into it, and the at least one hole (111; 711; 811) of the overlap extension (103; 703) of the second end and the at least one hole (111; 711; 812) of the overlap extension (102; 702) of the first end are adapted to align with one another to create a single path or channel in a radial direction for receiving a fastener that helps secure the support sectors (101; 701) together.
