Fixing a rim, remember that safety is of primary importance. Wear protective clothes, boots, gloves and goggles, and work in a safe and spacious area. Then, go as follows: 1. Take off the wheel and release the tire from the rim. Use a removal machine if you have it; otherwise, the pry bar will do. 2. Use the blowtorch on the deformed area of the rim. Heat each spot no less than for 2-3 minutes. 3. Use the mallet to bring the rim back into shape. You might need to put something (e.g. a wooden plank) between the mallet and the metal so that the latter wouldn’t leave marks on the rim. 4. Let the metal cool down and mount the tire back on the rim, then inflate it. The wheel can be mounted back on a car.
