When I got my combo, they used a cardboard circle in between two tire/rims (facing each other w/ the inside of the wheel facing out), also cardboard on the outside & used plastic strapping to hold them together...I s'pose enough packaging tape would do the same thing.

At least that way you wouldn't get hit w/ 4 unboxed charges in addition to the shipping charges...
