FWIW, the one time I used the classic PS4 (non-Tesla spec) 21" Michelins, they did NOT come apart and lasted 16,000 miles. Coincidence? Not sure.

Plaid 21” rear tire woes - factory defect?
- Thread starter KOL2000
- Start date
I sit 45 mins from home waiting on AAA because telsa cant get to it until the morning.. same situation. 15,329 miles and even wear but full separation. This seems to be a tire failure for sure.
21” on MS plaid 2023
It's definitely a tire failure, but due to a bad alignment and not because of a tire defect.
Yes, please submit photographs AND file a warranty claim with Michelin (Discount Tire is a pretty good supplier for replacement OEM tires BTW).
KEEP your old tires for your claim as you may need them for Michelin! (Michelin's website has a link where you can file your claim.)
Also, please submit a quick report here--every one of them will help get these junk tires off the road:
Report a Safety Problem | NHTSA
File a complaint with NHTSA if you experienced a vehicle, tire, car seat or equipment safety problem that could be a safety defect.
When you launch you are compressing the rear and adding -2ish degrees of additional camber. If you start with over -2 then combined with the stiff short sidewalls you gat crazy tire wear. The toe also changes but I'm not sure if it is in or out during compression. Whatever direction it is you should set it to the other end of the factory spec so it's near zero during a launch or hard cornering.
Could the inner eage be rubbing on something?
Could the inner eage be rubbing on something?
For the 59th time, the SIDEWALL tears away from the tread, eventually leading to a nearly impossible to notice pending tire failure with ONLY the OEM 21” Michelin tire mounted on the Plaid MS…and NOT the 19” OEM Pirelli tire.
It is NOT a wear issue.
And, NO, the inner sidewall is NOT rubbing against anything for those that are wondering why the inner sidewall often looks like it's been in a lathe. It's likely just an artifact of the tire's internal destruction, which now two+ years later Michelin appears to STILL not care about. Mind blowing. I guess no one at Micheline knows about this fiasco?

No. When I switched to the 305 NF0 Pirelli rears I chalked them to check this. The Pirellis are close to 1" wider than the OEM PS4S. The PS4S is on the bottom and NF0 Pirelli on top for comparison. If these don't rub, there is absolutely no way the PS4S are.
Yes, and if there was something in the wheel well in contact with the tire it would quite shiny and bright.

That's a lot of meat! They fit on the OEM 21" rims? And don't delaminate the way the Michelins do?
Yes, they fit the oem wheels. This is how they look on one of my sets of wheels, these are OEM spec - 10.5x21 45et They fill it in to the perfect size.
I did have tire wear problems with my first set of factory tires, but then put camber arms on and had an alignment, and zero issues now for 40k miles.
