These cause tiny pinhole leaks, so slow that they don't affect rides, so you don't notice until much later.
The thin tread of worn tires compounds the problem, but it's more about your move to the Southwest.
Consider using a liquid sealant and/or replacing the worn tire.
Thank you for your input!
Unfortunately, I can not paste the pictures. In the pictures I took today the damage points are located on the side of tube (neither outer which is in contact with the road, neither inner) and is surrounded by a large number of small holes/imperfections of the tube as if the material was aged or as if there was an excessive rubbing of some sort. I does not look like a single point of damage. I wish I could attach the pictures. Eight more posts to go before I can do this.
