Video: How do you change a bicycle tire?Changing a flat tireWhen changing a flat tire on your bicycle, the first thing you want to do is disengage your braking system. You can disengage your brakes by squeezing them together and removing the cable from its holder.

Next, you will use the quick release to remove the wheel from the bicycle. The quick release is very easy to use. You flip the lever open, unthread it, and your wheel will come right off.

Now, you are ready to change your flat. Make sure you have the correct size of tire inner tube for your bike. In addition, you will need tire levers. Tire levers make changing the tire on a bike much easier.

Next, you will need to remove the tire from the bicycle. If the tire is not completely flat, you will need to remove all the excess air from the inner tube before taking it off the frame. Release the air by pushing down on the pin inside the tire's air valve. Then squeeze the tire all the way around to make sure all the air is out.

Now, you're ready to insert your tire levers. Take one tire lever, and insert the thin end of it between the tire and the rim. Pull the lever down and clip the hook onto the nearest spoke. Then move over two spokes and repeat the process with a second tire lever. Move over two more spokes and repeat the process with a third tire lever. Then, you can take the first lever out, move over two spokes from the third lever and repeat the process. Work around one entire side of the wheel like this until the tire is free from the rim on one side.

When one side of the tire is off the frame, pull the other side off with your hands, and then completely remove the tire from the frame. Now, you can remove the old inner tube from the tire by simply pulling it out of the tire with your hand.

The most important thing when changing a flat is to check and see what caused the flat. Carefully inspect the tire to see if you can find what was causing the flat. Do this by gently running your fingers along the inside of the tire to look for any sharp objects. Be very careful while you're doing this and pay attention so as not to jab yourself with any sharp object that may be inside the tire. If you find something, remove it from the tire so you don't damage the new inner tube.

Now, you are ready to insert the new inner tube into your tire. With a bicycle pump, you want to put a couple pumps of air in the new tube just to give it shape. Then, put the new tube in your tire. Find the hole in the rim for the inflation valve, and pull the valve on the tube through the hole in the rim. Then, pull the tire over the wheel.

You will need to work around the wheel with your fingers, pushing one side of the tire into the rim. Once you have one side of the tire on the rim, check to make sure the inner tube is not pinched anywhere in between the tire and the rim. If it is, you will need to gently pull it out.

When one side of the tire is done, turn the wheel over, and work around the other side of the tire with your thumbs to push the wheel back onto the rim. It may get more difficult as you go along because the tire will become taut, but just push firmly with your thumbs until the tire is in place.

After the tire is on your bicycle, you are ready to re-inflate it with an air pump to its recommended pressure.

Then put the tire back on your bike, and reattach the braking tube.
