PROBLEM TO BE SOLVED: To provide an assembly of a tire and a rim which achieves reduction of low noise by suppressing cavity resonance and offers excellent weight reduction and run-flat traveling durability, and a support ring used therefor. SOLUTION: In an assembly of a tire and a rim, a support ring for noise absorbing/load receiving is arranged in a tire inner cavity surrounded by a tire and a wheel rim for rim-assembling the tire. The support ring consists of an annular base body made of an elastic material surrounding the circumference of the rim and provided with recesses opened to the tire inner cavity with a space, and a noise damper which is fitted in the recess and made up of sponge material. The sponge material has an apparent density of 0.1 g/cm<SP>3</SP>or less, and is fitted so as not to project to the tire inner cavity side from the recess inlet surface.
