I have a 2022 Y with 8,000 miles and so far, no noticeable wear on the tires. Previously I had a 2018 Kia Stinger GT2 with Michelin Pilot Sport 4S tires, larger in the rear. The tires were rated at 30,000 miles, but at around 16,000 miles, when in for an oil change, they called me out to the shop to see something. The car was up on the hoist and they had noticed the tires! From walking around the car, the tires looked normal, but from under the car - here's a couple of pictures. . . . . . . .

Kia insisted it's a tire problem, not a car problem and sent me to a Michelin dealer. They sent pictures to Michelin who responded with - It's a known issue with Kia Stingers and not really a Michelin issue, but they were guaranteed for 30,000 miles, so they would give me a 49% (based on mileage), discount on new tires- all 4! Combined with an ongoing special sale, etc., I wound up getting a new set of Pilot 4S tires for $618 including taxes, mounting, etc. This seemed quite fair to me on the part of Michelin and only a bit negative about Kia.
When I first got my Y I went on a 3,000+ mile trip and the car initially was very hard to keep in my lane. It felt like the caster was not as negative as it should be, perhaps even slightly positive. I looked the caster up in the service manual and found what it should be. Since it felt "wrong", I made a service appointment. The service tech seemed surprised, because the car had not reported a problem with the alignment, but had me come in so they could check it. They insisted it was set correctly and that it would adjust itself if needed?????? Took me for a drive and proclaimed it was perfect. I pointed out the slight feathering on the tread, indication of a possible caster problem, but they assured me it was normal.
As time went on, it drove better and better and the feathering disappeared. Perhaps it actually does have alignment sensors and makes adjustments it feels are needed? Seems pretty far fetched to me, but my experience seems to bear it out. With 8,000 miles the tires are all looking good and the car drives like a dream. After 6 or 8 software updates over the 11 months since I got it, the driver assist functions have improved to the point I am no longer frightened by them, have learned to pretty much trust the car, keep an eye on it, but enjoy the ride.
I've always had very good luck with Michelin's, except for that one set, which were made in India and shipped to South Korea where the Kia was built - so I suspected it was really a tire problem, but who knows. The Y has Continental tires which as so far looking good.
