Unfortunately my shop doesnt have any spare 55 gallon drums to lug around but its a good idea! Instead I was taught to face the outside of the rim away from you and stand it right up against your legs, then grab the face and squat while leaning back to flip it 180 towards you onto your knees/ thighs, then just keep your back straight and stand. Larger truck tires (especially those low-pro customs) can be a bit more difficult, but the same principle applies, you just gotta work it up your thighs a bit more before standing up. It sounds more complex than it is in practice tbh lol
