Patching a Bicycle Tire Inner Tube

crwdns2915892:0crwdne2915892:0

You will be taking the wheel off of your bike, removing the tire from the wheel, and patching the hole.

Notes:

  • Make sure that the wheel is fully deflated throughout the process, except for finding the hole.
  • When applying the rubber cement to the hole, the thinner the layer the better, for faster drying.

    • Insert the flat part of a tire lever under the tire coping. Apply pressure to the other end of the lever to lift the tire up and out of the wheel.

    • Slide the lever around the circumference of the wheel to completely remove the tire.

    • Alternatively, if you have multiple tire levers, see if you can clip the first lever to a spoke to keep it in place. Then insert the second lever a few inches away. Clip it to a spoke. Insert the third lever a few more inches along. Take out the second lever and insert it it a few inches past the third. Work along the rim until the tire pops off.
