Tip of the Day: Find the Source of a Flat Tire
If your bike has a flat tire you need to find the hole so you can patch it quickly and be on your way. The easiest way to find it is to add about 2 drops of dish liquid to a couple of cups of water and then pour this solution over the tire. Start to pump the tire and where the soapy water bubbles up is your leak. Now you can dry off the tire and repair it. This works for most tires.
