[AT] Confessing a complete lack of knowledge here

[David Bruce]

Thanks for the info. That's what I thought but I have been wrong before. 
I'm well aware of the tubes but it is always good to get a reminder. I 
think I'll try replacing the valve stem core first. If that doesn't work 
the tube is next for sure.
I just didn't want them to buy new tires when a less costly fix would work.
BTW the tire stayed pumped up for about a year. When they took the valve 
stem cap off there was a shot of fluid. Maybe a new stem will make 
things ok for a few years.
