A rolling suitcase (10), equipped with a pair of wheels (14) on one edge (18) of its base (26), can be transported by tilting the suitcase (10) so that only wheels (14) are in contact with the surface. A second set of wheels (20) are mounted on an adjacent narrower edge (24) of base (26). When approaching a narrow restriction the user would tilt suitcase (10) so that only wheels (20) are in contact with the surface, and proceed thru the restriction. A second embodiment utilizes a caster (36) near the corner of edge (18) and edge (24) in conjunction with a single wheel (14) or single wheel (20).
