Run-flat support system for a pneumatic tired wheel and method for installing same

A run-flat support system, comprising:

• a plurality of support segments positioned in a tire cavity of a pneumatic tired wheel, the plurality of support segments being abutted for an end-to-end mating engagement to provide a tubular support structure having an interior circumference defined by respective radial surfaces of the plurality of support segments;
• a plurality of fasteners for coupling the plurality of support segments in the end-to-end mating engagement;
• a torque assembly disposed within the interior circumference of the tubular support structure, the torque assembly including an integral and continuous substantially circular body and a plurality of mounting holes through the integral and continuous substantially circular body, the plurality of mounting holes being spaced to align with a plurality of wheel mounting holes associated with a split wheel rim;
• a peripheral flange coupled to an outer edge of the integral and continuous substantially circular body, the peripheral flange provided with a plurality of coupling holes spaced therearound for fastening the plurality of support segments to the peripheral flange;
• and
• the split wheel rim secured to the torque assembly.
