Yes, Pirelli is the OEM tire in the 19" size, of which I would speculate is about 60% of the Plaid tire fleet.That’s because there is no OEM 21” Pirelli tire on the Refresh S. They are all Michelin PS4.
Yet, despite identical levels of power, and likely similar driving modes, it is ONLY the Michelin tires that have tread separation and peculiar wear . . . which very, very strongly suggests that since we have yet to hear of even one Pirelli tire failing in this manner, it is very much a MICHELIN tire failure mode, either or combining, tire design, manufacturing, or some other defect unique to MICHELIN's tires.
