When you pull out the inner tube, you can pump it up and look for the leak.
If it's in a consistent place, you've then got a very specific spot on the
tire or rim to check for sharp stuff. If it's somewhere different each time,
you've got some other problem. If it's of the "snake bite" variety (two holes
right next to eachother), that's most likely caused by being pinched between
the rim and some bump you hit, in which case the cure is to pump it up to a
higher air pressure (so it doesn't compress as easily). If you are just
puncturing it a lot, there are a number of things to try. The most obvious
is to avoid riding through broken glass if at all possible, and to brush the
tires off immediately if you do (one of the things cycling gloves are useful
for). Switching to a different type of tire or innertube can help too. My
most recent rash of frequent flats stopped when I switched from lightweight
high performance innertubes to the heaviest cheapest tubes I could find.

Hmmm. I've found that it tends to go flat slightly less if the air pressure
is low, which is not consistent with the snake bite theory. Maybe I'll try
to find heavier duty tubes...but as it is, I'm not a big biker, so the tubes
I buy tend to be pretty cheap already. :) Tis a timely discussion in any
case, as I left my rollerblades in California. No comment as to where I've
left my heart. :)
