flat tire question

I recently had a rear tire go flat. Inspecting the tube, I found a pin hole
near the valve, but I can't find a corresponding hole in the tire. I've used
the tire for a bit since with no problems. So do most people replace the
tire with every flat or is that not necessary?
Thanks.

God, no. I'd go broke. Just check for anything sharp in the tire.

When you say "near the valve", do you mean on the rim-facing side? In
that case it's not a tire issue at all. If it's on the tire-facing side
then it's possible that the foreign object could still be embedded in
the tire. Sometimes these are very hard to find -- for example a piece
of fine wire a couple of mm long such as come from car tires that have
worn down to the steel belts. It's useful to mount your tire so that
the valve is aligned with the tire's label. This way, when you have a
flat you can estimate the area of the tire involved once you find the
hole in the tube. It also helps to rub your thumb along the inside of
the tire. Often it's easier to feel the object than to see it. All
that said, you can sometimes still not find the thing and ocassionally
I've had more than 1 flat from the same object before I finally found
it. Not a reason for throwing the tire away unless the cords have been
cut through.
