How to change and fix a flat bike tire
If you are a cyclist, you will inevitably get a flat tire. Getting a flat tire is a hassle, and disrupts your ride, but it’s easy to fix if you’re prepared. Always make sure you have all the proper equipment and follow this easy tutorial on how to fix a flat bike tire and get your bike rolling again in no time.
1. Detach the Wheel from the Bike
● First, release your brakes. Most brakes use a quick-release system to disconnect and reconnect them. However, not all bicycles have the same type of brake systems.
● Next, remove the wheel. Removing the front wheel from the axle should be easy. Release the brake, open the quick-release lever, loosen the skewer and pull the wheel from the fork dropouts. The rear wheel is harder. Proceed by shifting the chain onto the smallest cog. Turn your bike over and then turn the release lever of the axle to remove the wheel.
2. Get the tire off the wheel
To get the tube off the wheel, first, deflate the tube if there is still remaining air inside. Next, slip the flat end of a tire lever under the bead; hook the other end onto an adjacent spoke. Insert a second lever under the bead and slide it between the tire and rim until one side is completely off. Remove the other side and pull out the damaged inner tube.
3. Inspect for Damage
Using your fingers and your eyes, check the tire, inside and out to identify what caused the flat. Check for any sharp objects which could have punctured the tube.
4. Installing the New Tube
Before installing the new tube, add a few pumps of air to avoid pinching the tube when putting it back. Starting with the valve stem, lower the tube onto the wheel, inserting the valve into the rim valve hole. Then, proceed to push it into place around the rest of the tire.
5. Inflate Carefully
Now inflate your tire slowly to its recommended pressure.
6. Knead the Tire Back into the Rim
Put one side of the tire onto the rim and fix it properly, making sure there is no pinching. Proceed around the wheel, pinch both sides of the tire in towards the center of the rim.
7. Re-attach the Wheel
Fit the fork onto the skewer and tighten.
Hold up the bike’s back half, then focus on getting the wheel positioned so that the cogs are anywhere in between the chain. Then, set the bike down and tweak until the frame and wheel are properly mated. Tighten the skewer and brake, then roll.
