Looking for ideas on how to Roll up/store 50 amp cord

Never worked with heavy power cord, but with heavy extension cables for a winch I found that coiling around a drum by hand is nearly impossible. But feed it into a cylinder, much easier. (Haul 150 feet of 1/2 inch cable in a 14 inch car tire. Roll down to vehicle that needs pulled. Hook to load, roll back to feed out cable. At end, hook to winch cable with cable thru tire. As pull in, tire comes up with, and if breaks the tire slows the whip)
