Taycan Problem - potential catastrophic tire failure

[tigerbalm]

This thread is going to make me keep a close eye on my (Pirelli NF0 tyre) thread.

This is not a tire issue, this is a Taycan issue.

Why the title ”Goodyear Tire Problem” then?

The NHTSA complaint "TIRES August 7 2023" is available at this link: https://www.nhtsa.gov/vehicle/2020/PORSCHE/TAYCAN

Because I thought the tires were the problem when I started the post. Evidently not. I've renamed the thread, and hopefully this will go in the 'general' category. This is really important.

Same problem here.
Rear tyre on passenger's side started to loose pressure.
I verified and the inside face was like in pictures.

25.000 km.

The other tyre was ok.

Excessive toe-out, combined with tire pressure on the low side, causing stress on the tire and beginning delamination?

This is very troubling. Looking at the innermost treadwear indicators, the tire is fine. You have to go to the very inner edge of the tire to see unusual wear.

It also doesn't appear that the drive mode is the issue. What about 4 wheel steering - do the failures have this in common? I have 4ws.

No, I have not 4WS, but I have PDCC.
Later I'll load some front tyres pictures.
Very impressive.
13.000 km only.

My rears were replaced last week after it's 1st service.

RWD / 20" / no RWS / Michelin PS4 / 16k miles.

I knew they were ready for change soon (states 70% worn) - but it was both inner shoulders that I was unaware of, until it was up on the ramps for service.

This was from the dealer service report.

What tyre pressures are you guys with problems running?
Do you check and correct them based on the pressures reported in the “My Porsche” app or do you set them at a level on the car door sticker for light or heavy loaded?

I'm seeing the beginnings of a separation of the tread and sidewall in this pic. This is a massive problem...

41 psi all around - as received from the dealer when my tires are swapped. I have always had the tire pressures displayed on my dash.

I always try and keep mine in line with the app / car display.

I wasn't too concerned as 16k on a RWD Taycan seemed reasonable wear (I used to get 20k on my BMW M2 rears. Same tyres).
All the extra weight and torque of the EV etc.

But this thread will have me checking them more often.
Thing is the tread still seemed ok and I wouldn't usually check the inner shoulder.

I set mine to the sticker in the door frame….in my case 41 for the front and 44 for the rear….when cold.

DO you by any chance drive the car in lowered mode most of the time? I suspect that the camber changes when we use the car in any mode other than normal (where the camber is measured); so range mode, sport plus, etc. all lower the car and potentially unevenly use the tires....

Interesting. Now I put the tires pressure gauge on screen to monitor them. My tires pressure +1 psi according to Porsche app recommended. 98% in normal mode Hope its doing fine.
