A tire and rim assembly with a plurality of dispensing means adapted to release material into the inflation cavity upon operation of the assembly with the tire in the deflated condition to, for example, minimize damage to the tire cause by operation after deflation. The dispensing means are mounted in a balanced array so that each dispensing means lies at least partially in the well of the drop-center rim, and the dispensing means define a clear arc in the well which is adapted to receive portions of the beads during mounting of the tire to the rim. The clear arc of the well may also receive the beads of the tire during demounting of the tire from the rim assembly. Thus, the tire may be mounted to or demounted from the rim assembly by a method which incorporates the ordinary "buttonhooking" procedure commonly utilized with drop-center rims.
