Step 1: Removing the wheel makes it easier to fix flat bike tires
When you fix flat bike tires is easiest when you’re able to remove the wheel. If you don’t have wheels with quick releases this might not be an option.
Step 2: Removing the inner tube
Now it’s time to remove the inner tube. There are two types of tire lifters to pop the tire from the rim so you can reach the punctured or busted inner tube. Metal or plastic. Always use the plastic (black) tire lifters! Some outer tires need a lot of force between the edge of the rim and the tire bead.

Step 5: Installing inner tube
Now the inner tube is patched, it’s time to install it. You need to keep just enough air in the tube so that it’s not entirely flat. This will aid in the tube having it’s correct shape in the tire and not getting twisted or squashed.
Step 6: Installing outer tire
When installing the outer tire, start with the valve. By pressing the valve back into the rim there’s more space for the tire bead, making it easier to get the bead over the rim. If the tire bead is over the rim at the place where the valve is, work your way on either side of the tire, pressing it over the rim.
