Slow Leak

The Culprit

Dennis had a slow leak in one of his tires. We were talking about it at lunch yesterday, speculating on what could the problem. I said 'nail', Jack said 'screw', then Dennis goes home and sends us a picture of what he found. I am surprised, I would have thought something like this would result in the tire going flat immediately. It's new-ish car with new-ish tires, can't be more than a couple of weeks / years old. Guess new tires are tougher than they used to be.
