How to Patch a Tube (with a Glueless Patch)
Why waste your money buying a ton of new tubes when you can patch your old tubes and reuse them? A well-patched tube is just as strong as a new one, so let's get to patching.
You'll need a patch kit. Glueless patches will work and sometimes last a long time, but they're best for quick, roadside fixes.

Let's get started:
1. Find the leak.
Put a little air in the tire, then try to pinpoint the leak. Sometimes the hole is big enough that you can find it by the sound of the air escaping. Other times the hole is so small that you have to slowly pass the tube by your ear, face, or even eyes to notice where the air is coming out.
(Your face and especially your eyes are delicate, which is why they will notice the air.)
Some people recommend the water method, which requires you to submerge the tube under water and look for air bubbles, but that is too much work for this simple process.
2. Check the tire, tube, and rim.
Once you have found the leak in the tube, check the corresponding area of the tire for glass, thorns, or other debris. You should also check the rim for sharp edges that may cause flat tires.
Remove any contaminant that could have caused the flat.
(If there are two big holes in the tube like a snakebite, then you have a pinch flat. These are usually caused by not running enough air pressure in the tire.)
3. Scuff the tube.
Lay the tube out flat and use sand paper or a metal scraper and scuff the area around the puncture. Make sure to scuff an area slightly larger than your patch. Then wipe off any dust.
4. Patch it.
Grab your patch and peel the foil off the sticky side. Then fasten it onto the tube, sealing the puncture. Take care not to touch the sticky side.
5. Press it down.
Press down on the patch firmly to ensure a good seal. Press from the center out to the sides to remove any air bubbles. (Hold it in place a few seconds, too.)
6. Peel off and go.
Now you can peel the plastic layer off the patch.
The tube should be all set now, so put it back in the tire, inflate, and ride away!
