My 718 S was in the OPC Workshop for a software update. As part of the service the did a winter safety report, including tread depth.
The front tyres were both about 6.5 mm, the rears 5.7 mm.
They were new 2400 miles ago..I was old by the dealer.
New tyres here are 10.0mm... so the rear tyres have lost 4mm which is 2mm per 1000 miles.
That means that when the tyres get down to 2.0mm, the lowest point I'll live with, it will be 6000 miles.

Is it the P Zero tyres, or am I just a lead footed hooligan???
Or were the tyres really new?

I'll be watching this, carefully.

As per Scrounger - you are wrong about the original tread.

I'm not sure if that is good or not!
I've therefore used 1.6mm in 2500 miles = 1560 miles per mm.
Changing tyres at 2.5 mm average that means there is 5mm of usable tread, so 7800 miles life: about a year of normal use!
I guess we have to pay for our pleasure......

I know, but my Morgan Aero Plus 8 with 367 bhp and RWD doesn't wear its tyres as quickly.
But it isn't a turbo and the torque arrives more slowly....

Chris, what do you take as the wear limit?
Rules say the wear bars are at 1.6mm, but I feel that for a performance car that is not enough grip, I use 2.5mm as the "limit"

I'm also in the South, in Wiltshire and agree, 2.5mm to 3mm has to be the limit.
I'm not overly impressed with the P Zeros. The AMG C43 has PS5s for summer use and the Morgan PS4S and both are predictable.
We have Pilot Sport Alpines on the C43 for winter use and they are amazing, they just grip, even on packed slush.... I guess it helps that the C43 is AWD.
Our house is on an unadopted road (track really) and it slopes up to the surfaced road. Even with packed snow a few years ago the C43 just went up the hill and pulled away after stopping.

If the wheels were not so expensive I'd get a set of winter tyres for the Boxster. Instead I use the C43.

On a warm dry day with warm tyres, not a lot, BUT as the temperature falls and water is involved it makes a big difference to stopping distance and cornering grip.

 

[224 PJ]

It isn't just stopping in a straight line. Try cornering and braking on a skid-pan....that is when tyres are really put to the test.
But road surface, wear and road temperature play a significant role.
We are not driving shopping trolleys, but high performance sports cars. So time of year and geography also plays a part.
