I think I'll just buy new tubes next annual...

Why wait, that can be signed off anytime...

True, but I hate to do that kind of stuff mid-stream.

Unless the tire is flat, new inner tubes are one of those "as long as the
plane is up on jacks" kinda things, in my book.

Why not patch the tube? I have done it several times and have not
detected any problems. Just be sure to use the "hot patch" method.
