In this tutorial, we learn how to change a bike tire or tube. First, you will want to take the wheel off of the bike entirely. Then, remove the cap from the wheel and take off the nuts. Release any remaining air, then remove the retaining washers. Now use a lever to remove the wheel and tube from the rum entirely. Once you do this, grab your new tire or tube and inflate it slightly. Next, you will place the tire on and then insert the tube underneath it. Once finished, inflate the tire and then you will be finished and can place the wheel back on the bike to ride!
