Remove the Air from the Wheel

After sliding out the wheel, check and see if there is still air in it, inflated tube makes taking off the tire from the rim so much easier.

The tire has a bead, this bead pops inside the rim when we put an air pressure on it. First, unclip this bead out of the rim by pressing it hard with both thumbs. You will feel it when the bead pops out of the rim, then slide the tire tool carefully between the rim’s wall and the tire’s beads.

Use another tire tool and slide it in, just 2 to 3 inches away from the first tire tool. Push them both down to lift the bead over the rim wall. Leave 1 tire tool between the bead and the rim and slowly slide the other tire tool away from it,
placing the tire’s bead over the rim wall as you move it along. Some tires don’t fit tightly, so you can just use your fingers in this case.
