How To Change Your Bicycle Inner Tubes

The tools you need for this are:

  • Screwdrivers
  • Bike tire lever
  • Wrench
  • Replacement inner tube
  • Air pump
  • Safety Info: Be careful while dealing with moving parts, as you may get pinched.

Removing the Wheel From the Bike

First of all flip the bike over so it is resting on the seat and handlebars. If the tire is in the front, loosen the bolts on either side of the tire. If the tire is in the back, you must remove the chain from the gear before moving on to the next step.

Using a wrench, unscrew the bolts on either side of the tire then pull the chain off while rotating the pedals. Take wheel off bike frame

Removing the Inner Tube

Firstly, take off the cap from the valve, and remove the fastener. Stick the lever or screwdriver in between the tire and the wheel. Go around the wheel, taking the edge of the tire out of the rim. Note that you are not taking the tire off. Only one side of the tire needs to be taken out. Pull out inner tube then examine the tire for anything that could puncture the new inner tube.

Inserting the new inner tube

Get the new inner tube, make sure it is the correct size and type. You can find the correct size on the tire or the inner tube you just removed. Insert the new inner tube by placing the valve inside the rim first then insert the rest of the inner tube into the tire. Once the inner tube is half in, you can slightly inflate it to make this step easier. Press the tire back into wheel then tuck the tire back into the rim while turning the wheel.

As you’re doing this, be sure to check that the portion you’ve tucked back in is not coming out. When the tire is nearly all the way in, use screwdriver or prying tool to get the last bit back on. Be careful, as this is the most difficult step. If you push the tools in too far, you will risk popping the new inner tube.

Inflating the New Inner Tube

To do this, use a pump or air compressor to inflate the new tire then put the fastener and cap back on and you’re finished.


There may be other issues causing your inner tube to turn flat. If your inner tube goes flat again after following this tutorial, it may have been faulty, or something on the tire / rim may be poking into the inner tube.
