I remember watching a video on how Michelin Stars started out as a travel guide brochure for the best restaurants in France as a sort of advertisement for Michelin branded tyres (look at all these restaurants you could go to with Michelin tyres!).
How did the Michelin stars become so sought after by top restaurants and chefs? Was the head of the Michelin tyre company also a renowned food connoisseur or something? What about other tyre companiee, why didn’t they do something similar? Are Michelin Stars still given by the tyre company, or has it been spun off into its own thing?
And tyres aren’t cheap, which was the whole point. The Michelin Stars program was to show you what was worth wearing out your tyres more for as opposed to local stuff.
I would always advocate for finding local businesses to support, but that wouldn’t help a tyre company sell more tyres, now would it?
As for why other tyre companies didn’t do it, they didn’t need to. You don’t need to buy Michelin tyres to visit restaurants awarded Michelin Stars. The restaurant doesn’t check. They don’t even care. It’s not about the tyre brand for them. Certainly people with other tyre brands will go to places with Michelin Stars… but if you can’t afford Michelin tyres, you probably can’t afford to eat at places with Michelin Stars, either.
