Replacing innertubes without replacing tires?

I picked up a set of airstop-style tubes in my last AC Spruce order. I
was reviewing tire maintenance procedures and saw a recommendation that
you not re-use innertubes because they set slightly stretched and there's
a risk of pinching or folding them when they are reinstalled.

So, considering these tubes are new and my tires are decidedly NOT, would
I be "wasting" the new tubes on the old tires, or would it be okay to
reuse them on a future new tire?

I have reused tubes a number of times, usually successfully. When I
took them out after the second use, there was evidence that some folds
had developed. Once out of perhaps a dozen times did one develop a
small leak at the end of a fold.

How "decidedly not" new are the existing tires? If they're going to be
replaced soon, you could store the tubes until you need them. Of
course you run the risk that you might sell the airplane before that.

A&Ps have replaced several tires on my Warrior without replacing the
tubes. They always told me that they don't replace tubes as long as
there's nothing wrong with them. One time I finally had them put new
tubes in my old tires. For all I could tell, those tubes may have been
on the airplane since it was new. The new tubes really cut down on air
loss from the tires.

They're not new but they don't seem to be wearing out. So as you say,
they might have a long, happy life ahead of them, in which case I'd
like to get the new tubes in and quit inflating them all the time!

Thanks to everyone for the responses.

I never knew you were supposed to replace tubes. I went 30 years
on a set in my Bonanza.

Now that they are replaced, I can say the new ones leak about
as much as the 30 year old ones.

My new ones are butyl based (not "airstop", but another brand). They
should hold their air much longer.

Fill them with Nitrogen they won't leak as much. Not that I've tried it.

I've done it. No problem, my advice is to use talc powder inside the
tire. Use
plenty and the "new" tube will slip in the old tire with no hang-ups.

You can do it!

I put my tubes and tires on my plane recently and since my wife was heading
to the store I asked her to pick me up some talc. She brings in what she
said was the only powder she could find with talc instead of corn starch. I
have the prettiest smelling tires at the airport.

Talc powder helps alot. I always inflate then let the air completely out
again which should allow any folds or such to relax.

Some tubes have molding lines which can signal how much the tube has fretted
inside the tire. If a close inspection doesn't reveal much wear or
abrasion, I'll reuse them.
