Our '22 BGTS with ~5,500 miles has PZeros and after five track days and one AX day they are ready for the scrap pile. The replacements (PS4S) are in the garage and will go on after the next AX. Recently purchased a dedicated set of track/AX wheels and tires, so I expect to get somewhere in the neighborhood of 20,000 errand fetching miles on the PS4S before they require replacement in the future.

On the flips side, our PS4S shod '17 BS with 5,811 miles (when she was claimed by her new owner ) also had five track days and 4 AX's, yet still had a minimum of 5,000 miles remaining. The Michies wore so much better and were far quieter than the PZeros.

Thus, your silver lining is the sooner the PZeros devolve, the sooner you can swap in new Michelin PS4S tires...they're the bomb!

I wonder if a lot of the excessive rear tire wear is due the scuffing we get when we engage In wheel lock turns getting out of the driveway or parking lots.

I'm no engineer, but IMHO is that causes very minor wear and certainly not near as much as one hard breaking scenario (YMMV).

An independent Tire Rack video, for the doubters:

Wow, the stopping distance variations between the various tread depths are tremendous. Thanks, point well taken.
