I cut across a worn GP4000 some years ago. The wear dimples were still visible, but almost gone. I assumed there would be plenty of tread left.
No. the remaining tread was paper thin. The dimples are accurate.

Squaring off
I notice the rear squaring off quite early. But after that initial wear, it progresses quite slowly. I assume the wear surface is wider, so wear slows down.
I'm guessing 4000 miles on the rear tire. Then I move the front to the rear, otherwise it sits on the front for years, accumulating cracks and cuts.

More flats from worn down tires?
It's accepted wisdom, but is it true at all? The tread is maybe 2mm thick when the tire is new. How is that more cut proof than 1/2 mm at the end of the year?

Mileage
Tires wear out fast for strong riders. They are putting way more force into the rear tread, more often. Sitting and spinning is way easier on tire life.
