What's going on with this tire?

Looks like its a Michelin X-ice2 from the tread design, what is the date code on that tire?

We put my snow tires and noticed this weird spot. There are little sharp pieces projecting obliquely across the surface of the mirror. It looks completely bald in this area, and the profile looks all off. The rest of the tire seems fine. I'm scratching my head trying to understand what could wear a tire down in one spot specifically like that, and make it look like this?

Drove around and ride feels wrong - very rough. I'm going to get the tire replaced for sure, but would love to understand this. I've never seen those sharp looking quill-like projections before, and I've worn tires right down to the cords.

That’s a Michelin Ice tire and that wound is skid inflicted.

Very soft compound. I’ll bet it was on the rear and the car was driven with the handbrake on or with a stuck brake.

Likely your vehicle has independent rear, you left tires on well past snow season.

That was my first thought until people started talking about a broken belt/bulge. Hard to imagine someone not noticing a tire locked up long enough to wear down to the belts.

That said, it would be in OP's best interest to rule that out by making sure the wheel is actually turning on the corner the bad tire came off.

Like i said, broken belt. **** happens. Buy a new tire.

Broken belts don’t wear like that - it’s a skid from a locked up wheel. On a rear wheel with independent rear suspension, locking a wheel puts it up on its edge.

Do that to a snow tire on a warm day and you’ll burn thru the tire in less than 30 seconds.

In any case, that tire is done. It can’t be used now.

I'll take a pic of one in the garage later. 100%, it's a broken belt.

Tire is gone. Took car to the nearest place to me right after I posted.

Colour me impressed - Active Green & Ross asked me to come back in a week so that they could retorque the lug nuts. If I'm changing tires, I like to retorque them, but I have never had a shop or dealer *ask* me to bring it back to them for a checkup - and I've paid for a lot more tire changes or swaps than I've done myself.

And this considering they were so booked out for winter tire swaps they needed to have the car all day to be able to take me.

I think that has become standard practice. On the bill, they normally make you sign that you will bring it back for a retorque. I suspect it is driven by the insurance companies. When I got a set of tires at costco, for a retorque, you pull up in front of the garage and ask for a retorque, they walk out and check them all outside and you are on your way.

It’s a broken belt now - but there’s no way it broke then caused that damage. A broken radial bucks like crazy, the last 100 km of driving would feel like you’re driving over railroad ties.

I've had it happen multiple times. They last quite a while (can be thousands of km), it's not imminent doom. I had one go and it diameter increased almost evenly so there was no bumping but car pulled left (front ride turned out to be screwed). I got an alignment that fixed nothing (because it was a not yet diagnosed tire problem). Pulling the wheels off to diagnose and I finally figured it out.
