6. The Take Off
How To: Make sure that all of the air is out your tires. Some bike tires are easy to remove. You can pop them off with your thumbs. Others have a tight fit and will be more of challenge. If your tire proves difficult to remove, you may need a pair of tire levers. These are inexpensive and can save your fingers a lot of prying and pain. Don't use a screwdriver or anything sharp. You risk damaging the tire, and later on in this process you'll risk ruining your new tube. The butt end of a spoon or butter knife is a good substitute in a pinch.
