Tire age

So, aight den. I got Gladys' new tires put on today. I feel a lot better about the old tires. I found the valve stem was faulty on the tire that blew out. The entire copper center of the valve stem had come unvulcanized from the rubber stem and was leaking. I was able to pull the entire copper core out with my thumb and forefinger it was hanging on so loosely. So, it wasn't the tire's failure. The valve stem caused the tire to leak down and it lost contact with the outside bead and ruined the tire. Still though, eight years is a long time for tires and as soon as I get these two paid off, I'll be getting two more.
