Claim:
A dual structure tire wheel comprising: a rim wheel and an outer tubeless tire, wherein the rim wheel comprises a flange; a bead sheet for connecting a bead part of the outer tubeless tire; a well; a container defined in a space between a surface of the well and the edge of the rim flange, the container having a recess in its side wall; an inflatable inner tire contained in the container in a deflated state and protruding from the container in an inflated state, the inner tire having a projection in a radially inner part; a first rim valve for adjusting the air pressure of the outer tubeless tire; and a second rim valve for adjusting the air pressure of the inner tire; wherein the radially inner part of the inner tire is made of a rubber material and the projection of the inner tire fits firmly into the recess of the container so that displacement of the inner tire from the well by centrifugal force caused by the tire rotation is avoided.
