In this tutorial, we learn how to change a bike tire with CO2. First, you need to take the tire and wheel off of the bike. Then, release the air from the tire and then remove it from the wheel. After this, use a lever to remove the inner tube from the wheel as well. Replace this with a new tube and tire, then apply back onto the wheel of the rim. Line this up on the bike to place it back on, then screw all the parts back on. After this, tighten up your brackets and chain then you will be ready to ride.
