Tyres – never had this issue before on any car …

[ct4s]

Currently on the winter wheels.
At Porsche dealership, their scanner (used when they check the car in) showed the alignment was in the middle of green.

Raised the split with Continental.
Also, questioned the new tyre depth - was only 6mm!

Really impressed with their service - their tyre expert (Peter) called me a couple of times.

The split may have been a manufacturing issue (the tyre fitter scrapped it, so we’ll never know), but more likely the aggressive camber / toe from factory.
He suggested the alignment is done, but set to the lower limit of the factory settings which will definitely help.
When I refit the summer wheels, I’ll have it properly checked and reset.
Also, I’ll now run the pressures between the 2 recommended settings rather than the lower value. And go to the upper level if I’m doing lots of motorway miles.

6mm depth was normal for a high performance EV to (1) keep noise suppressed and (2) cope with the torque.
More depth and deeper blocks means more tyre movement.
To counter this, they worked hard on the compound to compensate for the reduced tread.
Make sense. Unless your Taycan batters the inner edges of the tyre. In which case you don’t have much wear in a set.

If it was Peter you spoke to then I think you mean Goodyear

Regardless, I don't think excessive camber caused your issue -see: https://www.taycanforum.com/forum/t...l-catastrophic-tire-failure.16788/post-493260

Checked mine yesterday and, thus far, they seem to be coping nicely on the inner edges.

Pretty sure this set of rears have been on 18mths and the wear is pretty normal/even across the tyre and will have done in excess of 20k miles.

• Hankook iOn Evo
• Have been making sure they're at 42psi (I have a feeling this might be the biggest factor...though the brand/model is different to the tyre whose shoulder let go...so that could be the biggest difference)
• I've also avoided using Sport/Sport Plus with any regularity (the car is reasonably regularly in the lowest chassis setting when on motorways/A-roads, which has been often)

Yes - my mistake, Goodyear [Peter].
Excellent customer service.

Agree - I'm now running nearer the full load PSI pressure.
