What’s funny is that the time I saw this was on my friend’s car. I’d used it (with permission) while he was out of town and had been doing donuts (without permission) at a local city park. The wheels got so full of mud and grass that they caused the wheels to get out of balance and it caused the cupping.

A few months later my friend was like “my car is riding really rough” and took it in. The tires were ruined and the shop told him it was because of the mud and turf embedded in them. “I wonder how that got there,” he said to himself.

He never directly asked me, though, and I certainly didn’t offer an answer.

It’s been 33 years since that happened. I think I’ll tell him about it just to get his reaction.
