Are these tires done? 2021 M5C

Only 4K miles on the tires, Pirelli P-Zeros, but multiple track days...
Thoughts on whether or not I should replace them? Thanks

No need to replace. They had some heat in them and you've picked up some marbles, but they should quickly fall off during normal road use.

They look pretty damn good for multiple track days.

Thanks for the feedback, they look good as you stated, marbles came off ... I'm still learning how these track days impact the car...

Let's address high performance tires at the track...

Unless CORDS ARE SHOWING, or unless you have rain to deal with (wet track), or the tires have "heat cycled out" (you have no traction while turning, because the tires have gotten "hard" due to the high heat cycles - hot and cold), high performance tires are good all the way down to NO TREAD AT ALL.

In fact, for dry traction, high performance tires are best at the lower levels of tread (the reason Tire Rack offers "shaving" service).

If you have to drive them home, you have to think about rain and tread and mud and snow, etc. But other than that, performance tires are VERY VERY durable.

Your wear pattern looks pretty good. I'd like to see the inside edge of both fronts, and the outside edge of the tire with the sidewall showing to comment on pressures, but what I can see looks good.
