How to Repair a Punctured Bike Inner Tube – Get Out the Tire Repair Kit

Luckily for you, you’ve come prepared and have a tire patch kit with you. Let’s walk through the steps on patching your punctured inner tube instead of just replacing it. There are many people that choose to just toss out their old punctured inner tube and replace it with a new one. The majority of the time though, your old inner tube is still perfectly useable and patching it will save you the cost of having to purchase a new one.

Remove the Tire

First things first, you will need to get the wheel off of your bike so that you can remove both the tire as well as the punctured inner tube (see the guide entitled How To Fix a Flat Bike Tire for more details). Take the inner tube and locate the punctured area. Puncture has been found, now what?

Get Out the Glue

When purchasing a bicycle repair flat tire kit you will probably have noticed that it came with the obvious items like glue and patches but your kit also contained a small piece of sandpaper. The picture below shows the contents of a typical tire repair kit.

Using the sandpaper, gently rub the area around the hole and roughen it up a bit.

Once that is done you will need to open your glue container. Spread the glue out on the inner tube so that it covers an area larger than the patch that you want to use.

Once that is done, it is time to relax and take in your surroundings until the glue dries. That’s right, until the glue dries or for about 5 minutes.

Glue Is Dried Now What?

Take out a patch and place it over the hole on top of the dried glue and press down firmly to get rid of any leftover air bubbles. Believe it or not the glue will adhere to your patch even though it now feels dry.

​You Are Off – Once Again

​That’s all there is to it. You can now insert your inner tube back into your tire and lever it back onto your rim. Before you do this though, you did check to make sure that whatever caused you this flat tire is no longer there to hamper you any longer, right?

​Once the tire is back on the rim you can re-inflate it back to normal cycling pressures and you are free to get back to whatever it was that you were previously thinking about until you were so rudely interrupted. That is your quick bicycle repair lesson on how to repair a punctured bike inner tube.
