Possible camber issue/inside of front tires worn

[myvaporblue5.0pony]

So we have had my 2024 Mustang GT/PP for almost 2 years. Front tires were factory installed. Well, today I suddenly lost air pressure going to work. Checked the tire out and found the inside of the right front tires was worn down to the wires. We went ahead and replaced both front tires because the right front tire was also showing excessive wear on the inside. We still had alot of tread on both tires. My question is has anyone else had this issue?

Edit: the attached picture does not show the tread remaining on the outside of the tire. The picture was taken with the tire still on the car under the fender.

Sorry you lost the tires, but happy to read nothing happened to anyone or the car.

I've seen the issue occasionally. We've had a thread or two of similar excessive wear, but nothing systemic.

I can't remember anyone having a bad component from the factory, something needing replacement. The fix has been getting an alignment, correcting for something out-of-spec from Flat Rock.

There is a coupon period for a free alignment at the dealer. Unfortunately, that's only valid in the first 12 months of ownership.

That could be excess negative camber or toe out, an alignment is in order.
I have to say I'm shocked it's down to the belts, that's seriously dangerous.

That is a serious issue with alignment. You're fortunate nothing bad happened. Nothing that can't be fixed, I would hope. Don't see how it wasn't noticeable in the steering.

Yes kinda of a big a deal to the tires wear fast. Alignment should fix that no problem. It must have been out for a min to wear that much.. good luck

That wear is due to one thing and it is "Camber" setting in the alignment. Before more bashing on how your car is defective please post how many miles are on your car. The S650's factory have come at a -1 to -1.5 camber best of my memory, simple math is every 1° of camber you loose 20% of tread life, so at -1.5° that means loosing 30% of tread life. I do not know what tires you have, but on my dark horse that would lower the expected tire life to ~20k miles. The PP you have likely has more negative camber as I do not have access to the specs anymore as I retired a year ago.

Please post how many miles on your car

This is 100% false.

First off, the factory camber setting on both the base and PP GT is -1.0, which is really, really tame. Ask anyone who tracks their car. As a DH owner I'm surprised you are making these claims, and I'd love to see the data backing up those numbers. I had a Mach 1 with -1.7 camber and never had uneven tire wear like that. Unless you are throwing the car around on a track regularly, you will not wear the inside of the tires like that. Yes, they will wear faster, bit not like that. I know guys the drive around with -2.0 or more camber and don't have issues like that.

That wear is from access toe. Unfortunately the OP was driving around on a bad alignment for a long time. Always check your tires. That didn't happen overnight.

Looks like toe out. To wear that bad steering must have felt like crap.

Not just camber. As I said, it could be toe out.
I've never heard of such a direct relationship of camber to tyre life. Where did you see that?
FWIW I have worked in an alignment shop.

This may have some context to your question. So my 2 cents…

When I bought my 06 GT, it was used and already lowered with Eibach springs. A year or 2 after I had it, it was up on a lift and the mechanic and I noticed the inside of both front tires were badly worn almost to the point of being dangerous. I was told the camber was way off.

Research showed me that the S197’s have very limited camber adjustment, and can’t compensate for being lowered. I learned I had to buy a set of camber adjustment bolts and have them installed on the car. I took it to an alignment shop and they installed the bolts, put on new tires and did a full alignment.

So my direct experience was that badly cambered tires absolutely result in badly and unevenly worn tires.

Remember the Acura NSX? It handled so amazing because of neutral weight distribution and aggressive camber. To the point where owners had to get new tires every 10K miles.

I only have 22,973 on the car. Bought it new and it's basically my car I just drive back and forth to work and an occasional trip out of town. I never noticed an alignment issue. Seemed to drive fine. We did just have to replace the back tires cause of normal wear. My tires are staggered.

I never noticed an alignment issue.

Long post short: get an alignment, at the dealer or service shop you trust. They should provide you with a before and after printout of the settings.

I can think of two situations related to alignment.

There's the alignment issue you can feel. The car tracks to one side, is loose, steers poorly, etc.

There are alignment issues you cannot feel, but will prematurely wear the tires.

I feel your situation was the latter.

Long-term, two things I encourage everyone to do:

1. Check your tire pressures, using a good, manual gauge. TPMS and the Pass App are OK, but TPMS alarms when there is an issue. Manual checks are more accurate and can catch a slow leak.

2. Check the tire tread wear. Using a Milton or other tread depth gauge, I check my treads once a quarter and document the results.

Edit,

I see where your tires are staggered, so rotations are unnecessary. The Owners Manual will list when to check or rotate the tires. I'd check treads following that schedule.

It is very likely this will be the "norm" on your car. As others have brought up, getting your alignment done / verified is in order.

Best of luck. On My DH 700A I took control of this issue when new, 9,000 miles later I still have great tire wear all the way around still 8/32" even across the tire. I chose to fix this when the car had less than 5 miles on it, took a pair of camber plates modified them to move the tires closer to zero camber. The results are here in the photos; car has a few hundred miles under 9k on factory tires. Car handles and drives great, I know the suspension is not setup to favor track days, but not too many tracks between my home, bars and grocery stores.

These are photos of the front left, right side is the same and a bit too lazy to take photos of the rear, which I moved camber very close to zero on as well.

Thank you. We are definitely going to get an alignment when we take it in soon for an oil change.
