• wherein:
• the bottom flank defines a surface facing, in use, the ground surface when the luggage assembly is placed on the ground surface with the wheels in the unfolded position, the bottom flank having a push direction edge, and an opposite pull direction edge, the push direction edge facing in a forward direction when, in use, the luggage assembly is pushed by a user;
• and
• the rear side defines a surface coupled to the bottom flank at the pull direction edge, such that:
• the folded position of the wheels is within the luggage assembly,
• the unfolded position of the at least one front wheel is completely at a side of the bottom flank that faces away from the luggage item, and is positioned closer to the push direction edge than to the pull direction edge,
• the unfolded position of the rear wheels is completely at a side of the rear side that is facing away from the luggage item, and
• when the luggage assembly touches the ground surface with the wheels in the unfolded position and when the luggage item is homogeneously loaded, the luggage item has a tilted position with respect to a line perpendicular to the ground surface in which the rear side tilts towards the ground surface and has a projected center of gravity of the luggage item is in between the rear wheels, and the at least one front wheel, the projected center of gravity of the luggage item is a perpendicular projection of a center of gravity of the luggage item on the ground surface.
