Run your hand around the inside of the tire. If there's a nail or a large
piece of glass you'll feel it. Although some people warn that you can cut
yourself in 25 years I haven't. Also look very closely at the tire for a
thorn or piece of glass, staple or some such.
Often if you fill the innertube with air and put it in a bucket of water
you'll find the leak. Then laying the innertube on the wheel so that the
filler is in the correct spot you can then search that area of the tire for
foreign objects. Remember that you may have the innertube upside down.
Never put a new innertube on unless you've discovered the cause of the
original flat.
