Front tire worn down unevenly, why?

Thanks I do some more research, Not in a Hurry anyway..

Never noticed anything weird when I’d by driving my car but today I had it parked with the tires turned and I noticed on the inside of the drivers side tire it’s completely worn down. I checked the passenger side front tire and it’s fine. See the picture below. Any idea why this happened? It’s a 2019 bullitt original tires, original alignment, 10k miles.

Should new tires and an alignment fix this problem or could something bigger be at play here?

My opinion is the best thing you can do is go to a good alignment shop. Find a local place where the hot rodders go. You want someone who knows what they are doing.

We can speculate about what is happening, but there's no substitute for actually measuring how the car is set up. A good alignment guy will be able to help you out.

I'd say 10,000 miles is early to get that kind of wear. I suspect that the alignment will find an issue.

That's wear from excessive toe out, and also a wear characteristic of the Michelin PS4s. Once aligned, you should be good to go.

+1, exactly what caused it. Just on that side. Camber doesn’t wear tires that way. Also, these cars aren’t easy on tires front or rear.

Yes

That's a lot of negative camber from the factory, or something is lose or bent. I'm running -1.7 that's as much as the tech could get out of it stock. From the factory setting was -1.2.

I'd consider replacing all four. While the front two are the primary concern, replacing all four puts you at the same standard, all four wheels (same age, tread depth, brand tire, construction, composition, traction, etc.). Tires are one of the key components keeping you in control of a 4000 lb / 1800 kg rolling mass.

Afterwards (and not before), take to a shop that does alignments. Hopefully a locally-owned shop with good reviews and history. They can not only check specs, but review the suspension and ensure all is OK.

Once you get the above sorted, checked pressures and tread depth consistently. Rotate tires and perform a general hands-on inspection once a year. Tread depth checks and tire rotations should give you insight as to how the pressures and alignment perform over time and if you require any further adjustments.

Every car and environment is different. I've only had my alignment checked and adjusted during component changes. At the other extreme, someone who does a lot of miles in a city with poor roads might need alignment checks and adjustments much more frequently.

Ahhh.....the best that ChatGTP has to offer.

No, the OP can't rotate his tires. Anymore than you can with stock wheels & tires.

Are you mocking the random word generator, sir? Off to tech jail with you! Your AI overloads will not be mocked.

Plus @Skye is anticipating that OP will shortly come to his senses and buy real wheels (10 SQ). Like a boss!

So what would you guys do, replace just the front two or all four? I know I should probably do all four but these tires aren’t cheap and I don’t see how it could be a problem being as though the front and rear tires wear at different rates and usually end up different anyway. What do you guys think?

Also fyi, I will be replacing them with the same tire. In case that makes any difference.

Just 2 is fine. You drive a mustang. Budget for tires.

Ain't that the F'ing truth!

correct, the only adjustment from factory is toe. Jim

Why does the term "Set the toe and let her go" keep resounding in my head?
