ABSTRACT:
Removable large wheels for a luggage case, having two permanent sleeves inserted in holes drilled in the pre-existing small wheel mounting blocks which contain the pre-existing small wheels. Two axles, one in each of the sleeves, with a permanent stop at the inner end of each axle and a spring loaded button at the outer end of each axle. The large wheels have an extended tubular part at the hub on the inner side of each wheel which prevents the wheel from touching the outer edge of the luggage when installed. The axle can be extended outward to accept the large wheel, which is maintained on the axle by a spring loaded button. When not in use, the axle can be retracted back into the sleeve. When retracted the axles are prevented from moving in either direction by the pressure of the spring loaded buttons against the inner wall of the sleeves.
