I learned this trick on big (18 wheeler) truck dualls, but it does work on these trucks too. It eliminates the wrestling match.
Take a large piece of flat steel, like 2'x3', put it under the rear axel and pour a little oil on it so the tire will slide easy on it. Jack the axel to just past the height of the rim center, slide the tire right on or off. You will never have to lift that heave wheel tire combo up again. It saves a ton on the back, and the bad words! This works really good on the 18 wheelers when pulling the full dual wheel assembly off with the hub/drum assembly to service the brakes. There is some balancing trickery with the smaller truck tires and only doing one at a time, but the trick still works wonders. It'll definitely keep that powder coated surface off the rough brake drum.
