Yes, it depends on how much better the tire is (2x, 10x), but I still think this argument doesn't make sense. If Michelin don't use the technology, then another company might discover the secret tire and produce it and wipe out the competition in the industry. From Michelin's perspective they would have a golden goose of a product and would want to exploit that for as much profit as possible... Also, they're not just going to gain market share they would literally be the market-leaders in a new industry of long-lasting tires...
