How to Change a Flat Tire on a Mountain Bike: A Step-by-Step Guide
To change a flat tire on a mountain bike, first, find a flat and stable surface to work on. Next, remove the wheel from the bike by loosening the axle nuts or quick-release lever. Take off the tire by either using tire levers or your hands. Once the old tube is removed, check the inside of the tire for any debris that may have caused the flat. Insert the new tube and make sure it is aligned correctly with the tire. Inflate the new tube to the recommended pressure, put the tire back on the rim, and tighten the axle nuts or quick-release lever. Finally, check the tire pressure and give it a quick spin to make sure everything is secure and working correctly.
