My worst flat spot torture test of PR2s was: 1600 miles of slab to Denver at super-legal speeds, on a C14, no flat spot. Couple days of twisties, then another 1200 miles of slab to Ann Arbor. Was just able to feel the flat spot touching the tire with my hand in Ann Arbor. Another 500 miles of slab to Maryville, TN and the flat spot was just barely visible.

I'm running PR3s exclusively now, and they wear pretty similarly.

Unless you are dragging your front brakes all the time, the rear is going to wear out faster. You are always loading the rear any time you are maintaining speed or accelerating.
