Plaid rear tire wear - going after Michelin again - share your experiences?

[HighPotential]

This is my fourth set of Mich PS4S and the third set ready to come apart on the inner tread corners of each tire. When the first set (T2s) came apart at just over 6,000 miles Michelin stepped up and paid for a second set.

The second set did a bit better but didn't last very long either.

Third set, the only ones that were the original PS4S and not the T2 version, lasted 16,000 miles amazingly and kept at least 42 psi (40 recommended)

My current set (T2s), just over 7,000 miles again and only four months.

The car has been aligned numerous times confirming proper factory alignment existed each and every time.

I expect Michelin will not be as friendly this time.

Shared experiences, tips, tricks, etc appreciated.

Your poor tire mileage is a known issue. Tesla alignment specs don't protect your tires. To solve your problem you need to install adjustable camber and tow arms.

What were the alignment specs that you confirmed with them numerous times?

There are lots of threads on this subject. Tesla camber arms are non ajustable. Their alignment spec is very wide to ensure that the results falls inside the spec. Go to N2itive---- Eliminate Inner Tire & Premature Half-Shaft Wear On Tesla X/S! ---- and watch their short video. Good explanation of the problem and how to fix.

Probably "within spec" is what he was told. Assuming.

Interested to see if he went to a performance shop and they fixed the horrendous factory tolerances. Practically impossible to go through 4 sets of tires and have the same issue and it be the tires' fault. Better chance of winning the lottery AND all of the people you know never asking you for a loan.

If there is a real solution, I am interested...

mmmm. Looks promising...

You don't necessarily need these. I have the unplugged camber arms, but the issue is because of too much toe out, not camber. So an alignment by a reputable shop, not Tesla, will most likely fix the problem.

I have a lot of experience turning wrenches. I am close with the shop and get my head in there all the time when working on things. They are top notch. The last alignment we did was spot on but I also insisted on doing it in"low" suspension level. I have attached the latest results.

I assume you’re ending rear tires before fronts?

Adjust toe to zero, like your fronts, and watch abnormal wear disappear.

This is the first time I have seen a perfectly matched alignment down to the hundredth of a degree between both sides on almost every measurement.

Personally, no matter the shop that did this, I'd have to call those results into question.

AFAIK, this shop is exceptional. Been going to them for decades. It was a very new machine (then). Well, if anyone can tell me what the numbers should be, I will work with them today to adjust the rear.

Thanks, I will do that. What do you mean "ending" ?

Wiping / destroying / killing / ending the inside edge of both rear tires

I just asked one of the guys at my shop how they done that perfect alignment and he suggested that they should apply to work for a formula 1 team because he's never seen it either.

This was from late last year, I changed it a bit in January, but it's mostly the same on the rear. I like the rear toe to be roughly +0.15

honestly, might just be time to try a different tire.

His caster isn’t dead even on both sides so I don’t think they’re just copying and pasting.

Its not impossible on a DSP600/laser alignment system, but will require an abnormal amount of time over a typical ‘within factory spec’ alignment.

Here's what they found and what they did:
