Introduction

Sometimes, your tire's inner tube just goes flat. To fix that, you either buy a new one or patch the faulty one. Either way, you'll have to get the tube out of the tire, and this guide shows you how.

Use a wrench to loosen the nut holding the wheel's axle on one side.
  • Use a wrench to loosen the nut holding the wheel's axle on one side.

    • Once it's loose enough, continue removing the nut with your hand.

    • After removing the nut, also remove the washer under it.

  • Note how the washer has a small appendage that locks into a slot in the fork.

  • Do the same for the nut on the other side.

  • Unscrew cap from air valve.

  • Use a thin object to press down the pin in the center of the valve, releasing the air in the tire.

    • Note: We use a hex wrench in this picture, but you can use pretty much any blunt object that fits.

  • Take a tire lever, and wedge it between the tire and the rim. Make sure the end scoops inward to grab the tire.

  • Once you manage to grab the edge of the tire with the lever, pull the lever back to scoop the tire out of the rim.

  • Then, use the notch in the other end of the lever to keep it steadily anchored on a nearby spoke.

  • Do the same thing with another tire lever about 5 inches away from the first.

  • Do the same with a third tire lever even farther around the tire.

  • Then, leapfrog the second and third levers until the tire comes partway off.

  • Now, use the tire levers to wedge the tire off the other rim. This will be far easier than for the first rim.

    • As you do this, make sure you pull the air valve out through its hole in the rim.

  • Now, the tire (with the tube inside) should be completely removed from the rim.

  • Now that the tire and tube are off of the rim, gently pull the tube out of the tire.

    • Be sure to pull gently, because sometimes the tube can sometimes end up adhered to the inside of the tire.

  • Now, you've separated your tube, tire and rim.

  • To replace the tube, follow these instructions in reverse order using the new or patched tube.

    • Remember to inflate just a little bit of air into the tube before you try to install it, as that makes the process go much smoother.
