I had a coworker with an old Mercedes handed down from her parents. Old as in the car was older than even me. She ended up with a flat one night so a couple of us offered to help install the spare. Looking at the tire, we realized that her tires were completely bald and about 15 years old. We made all the usual comments about old tires needing to be replaced and so on. Then we pulled out the spare. It was the original that came with the car. The valve stem crumbled as soon as we touched it.
