It is this group of Prius owners that is different. From the early adopters to today's Prius advocates, we're the hybrid equivalent of a 'hot rodder' with an interest in getting the maximum performance. But I'll share one empirical data point.
When I had my tires rotated, the fronts had worn down to ~.55 inch while the rear tires had worn to ~.75. The difference could easily be the heavier weight on the front tires. By running them at a higher pressure (and 2 psi may not be enough,) they should suffer less wear.
