981 tyres scrubbing when turning

*bump*
I've just replaced Pirelli P-Zeros with GY Eagle F1 Asy 2 (Porsche N0) and the phenomenon has disappeared.

I did the same 30k miles ago. Wait until it gets a bit colder. It'll be back, but less pronounced.

PZERO does seem to be particularly prone to this. I changed fronts to PS4S and the issue is massively reduced. I can only assume PZERO has an extraordinarily stiff sidewall.

P-Zero is just a st tyre all around really. Clearly all the positive magazine tests are “paid” for ...

I'm pleased this thread got refreshed, I'm relieved it's not just my car! I changed to a 981 pdk from a 987 manual recently, had a bit of scrubbing on the 987 but it's a lot worse on the new car.
I've got the P Zeros with loads of tread left and a tight turn in and out of our drive so probably worst circumstances.
I had my car in at the specialist I bought it from yesterday for the drain holes checking and the service manager explained the reason for the scrubbing, same as a lot of the comments on here.

My wife’s 718 does this. I assumed it was something to do with the geometry. I googled it and found a forum where loads of other Porsche owners had this too.

Is it a Porsche thing (seems to happen on lots of models) or a tyre thing? Or a Porsche thing made worse with certain tyres?

I’ve not seen it with any other car I’ve had on the same driveway.

ETA p zeros on her car too.

Google Ackermann effect. Sounds much worse than it is. But perfectly normal and worse on some tyre compounds.

Thanks, makes sense.
