In this video, we learn how to change a mountain bike tire. Start by shifting the rear cassette to the smallest gear. Then, remove quick release and remove the wheel. After this, remove the tire with tire levers or strong fingers, then check inside the tire rim for foreign objects. Inflate the new tube slightly, then put the tire in. Put both of these inside the rim, then inflate the tire to the correct PSI. After this, install the wheel on the bike and then tighten quick release. Do the final check by spinning the wheel and if everything is running smoothly, you will be finished!
