This company ships their wheel wheels in same boxes as the manufacturer supplies them in. This type of box is meant for very large shipments where the wheels are paletized and secured together so there is very little movement of individual boxes. The box is not designed to take the strains of being shipped individually. In an attempt to minimize damage the shipper has taped on pieces of cardboard at the wheels lip where it would contact on impact. There is however nothing to absorb any impact , the dense cardboard at the lip will just transmit forces directly to the wheel.
This company ships their wheel and tire package using a single piece of cardboard to protect the front and back side of the wheel, with only one sheet of very thin foam between the face of the wheel and the cardboard. The whole assembly is tightened down with plastic shipping straps. Failure of this type of shipping is highly probable, either from inpact / puncture at the face, or the plastic strapping breaking during freight. Not to mention that the tire has literally no protection at all.
This company ships their wheels in one, single wall box with folded cardboard at the center of the box sides to protect the wheels lip, and a single piece of cardboard between the wheels to keep them from hitting eachother. While this technique may protect the wheel in an ideal situation, it is most certainly suceptibe to the wheels damaging eachother in transit, or worse, the box splitting and spilling the contents.
