The 18" Michelin MXM4s that came standard on my 2019 M3 were not great. Only got to 23K. And they're expensive. Went with the Continental EXTREME CONTACT DWS06 PLUS. Seem just as quiet (or loud, however you wanna look at it) as the Michelins even without the foam core, which, incidentally, makes them easier to temp patch on the road if need be.
