Here is a simple answer to your question. Yes Pirelli has different tread wear ratings on the P Zero tires. A Brembo car has a 220 rating which will wear out fast and the non Brembo cars have a 400 rating which will last a bit longer. I have had both versions.
That's not the question I raised. I asked specifically
about the Brembo PP/Track Pack Pirelli MO (Mercedes Original) OEM tires that come on the cars from the factory.
The mileage people have gotten out of them is all over the map. So with the exact
same tires, Pirelli has changed the compound over the years. And I don't remember where, but I read something to that effect somewhere in the last year or two.
