Patching a bike's tire inner tube is much easier and faster than it sounds.

To complete this How-To you will need:

An inner tube with a puncture
A bicycle patch kit, consisting of patches, glue, and a square of sandpaper
A bike tire pump
A big bowl filled with water (optional)
Towel (optional)

Step 1: Remove the flat tube from the tire

Remove the flat inner tube from the tire.

Step 2: Attach tube to a pump

Attach the inner tube to a bike pump.

Step 3: Pump up the tube

Pump up the tire until it's full of air.

Step 4: Listen for the escaping air

Listen for the hiss of air escaping from the tube. Bring it close to your ear to help.

Tip: Using a bowl of water, run the air-filled tube through the water. Look for a stream of bubbles emanating from the tube. That's where your hole is.

Step 5: Let air out of tube

Cover the hole with a finger, detach the pump, and let all the air out of the tube by pressing down on the valve stem.

Step 6: Lightly sand the area around the leak

With your sandpaper, lightly sand an area around the leak larger than your patch.

Step 7: Wipe the leak area clean

Wipe clean with your hand or optional towel.

Step 8: Cover the sanded area with glue

Cover the sanded area with glue.

Step 9: Let the glue dry

Let glue dry for 5 minutes.

Step 10: Put the patch over the leak

Separate the patch from its backing and place directly onto the tube, pressing it firmly into the glue.

Tip: A good rule of thumb is to replace a tube after you've patched it three times.

Step 11: Remove the cellophane cover

Remove any cellophane cover over the patch and you're ready to go.

Oh shit, now the back is flat.

I'll put 10 patches on a tire if I don't get a flat IN a patch first. lol. Don't forget to scrub out the tire so you don't bust it again right away if thorn is stuck in there.
