In this tutorial, we learn how to change a bicycle tire & replace the inner tube. First, take the wheel off of the bike. Then, see if you can find any holes on the outside of the tire. Then, remove all air from the tire tube and remove 1 side of the tire using tire levers. After this, completely remove the inner tube and then inflate the tube and check for holes. Check the inside of the tire for sharp objects, then find out which way your tire should roll. Install one bead of tire back onto the rim, then insert the valve into the valve hole. Insert the rest of the tube inside of the tire, then work the second bead of tire onto the rim. Now place the wheel back onto the bike and you'll be finished!
