It’s totally possible for factory tires to wear out quickly, though I haven’t run into that issue with Michelin’s in the past. The stock Goodyear RS-A tires on my old Mazda 3 were toast at 22k miles. The Mazda did have a lot of negative camber, and would chew up tires unless they were cross rotated (vs. just front to back) to distribute the wear. I had to make sure to buy asymmetrical tires so I could swap them side to side vs. directional. I still have to do that with my Mazda 5. I haven’t noticed any undue tire wear on my 10th gen, but it’s a hybrid with LRR 17’s, and I’m only around half your mileage.. Still, the suspension setup is the same (minus the adaptive dampers) so I’d think I would have the same problem.
Beyond that everything else with tire wear comes down to driving style, and how you rotate. You can put two identical cars/tires side by side and the aggressive driver will wear them out sooner.
