A piece of luggage (1) comprising a housing (2) and at least one pair of caster wheels (9), wherein each of the caster wheels (9) comprises a swivel axis (S) and at least one wheel (10) with a peripheral surface (11) rotating around a rotation axis (R) running perpendicular to the swivel axis (S). The diameter (D) of the at least one wheel (9) is as large as possible under the provision that in a rotational position parts of the peripheral surface (10) of the wheel (9) extend in a space between a center plane (C) extending centrally between a front wall (3) and a back wall (4) and a reference plane (P) extending parallel and at a distance (A) to the center plane (C), which distance (A) amounts up to 20% of the diameter (D) of the wheel (9).
