Removable large wheels for a luggage case, having two permanent sleeves inserted in holes drilled in pre-existing mounting blocks which contain 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 fastener at the outer end of each axle. The large wheels have an extended tubular part at the hub of the inner side of each wheel which prevents the wheel from touching the outer edge of the luggage. The axle can be extended outward to accept the large wheel, which is kept in place by a fastener at the outer end of each axle; or, when not in use, the axle can be retracted back into the sleeve and the wheels stored in pockets on the exterior of the luggage case. The axles are prevented from sliding part way back out of the sleeves by a fastener at a point just outside the inner end of the sleeve, and kept from slipping all the way out by a stop which is permanently affixed to the inner end of the axle and is of the same diameter as the sleeve.
