Eric, just for an FYI, I have shipped 15x8 rally wheels and the 15x8 6 lug steel wheels using cardboard boxes I have bought from Walmart or our local Menard's (big box lumber yard store). Cardboard boxes are 16'' x 16'' x 15''. Stacked two wheels in first box with piece of cardboard between two stacked wheels. Inverted the second box down over the first box and cut down to size. Think makes the whole boxed unit 16'' x 16'' x 19'' at 56 lbs. per box. Shipped thru UPS and worked out well. Hope that helps with some options.
