Interestingly, the connection is that Michelin also publishes the best road map in France. And when people drive their cars more and farther (to the best restaurants, for example), they need more tires.

P.S. The fact that tires are responsible for 50% of microplastics wasn't a big deal back then. Just like it is today.

P.S.S. I know, I know. I must be fun at parties.
