A baseplate for an article of baggage, e.g., luggage. The baseplate includes a support member and three or more wheels disposed on the support member along a substantially linear axis and arranged so that adjacent wheels are substantially equidistant to one another. This advantageously provides greater stability to the baggage while distributing the load substantially equally. The invention also relates to an assembly in which the baseplate is mounted to an exterior surface of an article of baggage and pivotable about the substantially linear axis when tilted so as to roll along all three wheels. In one embodiment, the baseplate has three wheels including two outer wheels and an intermediate wheel disposed therebetween. The diameter of the two outer wheels is the same and larger than that of the diameter of the intermediate wheel.
