How to change the Tube and Tyre on a bicycle

This instructable is for those people that want to know how to replace an old or busted tyre and tube from the wheel of a bicycle.

Step 1 Deflating the tyre

To deflate the tyre you need to find the valve, valves can come in two different types.
The road bike valve, the valve shown in the instructable
And the american valve (the tick one on bmx and mountain bikes)

The valve you show is called a Presta valve. The American valve found on the mountain bikes is a Shrader valve. (It does not matter, but it is frosting on the cake to have the information.) I have sometimes had problems around the valve stem. The tyre bead may not seat properly and the tube bulges out the side when I inflate it fully. To get around that, I like to push the stem up away from the rim and put both beads of the tyre on near the stem on first. I push the tyre beads down and let the stem area of the tube press down on the beads as I inflate the tube. It is very disappointing to have been careful, but still pinch an new tube with a tyre iron while installing it. It is more of a problem with tyres that are very tight going onto the rim. Thanks for posting this.

Just a note, a lot of BMX tires are outside your 30-40 PSI range, that is about right for most cheap tires, but many nicer tires will run around 80-100 PSI.
