I went through 2 Pilot Power 3 rears (one went for 4,000, then another rear for 6,000), and one front (10,000). I thought they were fantastic for the first 2000-3000 miles, then they started to feel like they were getting a little slick (coincided with the rubber melting heat of mid summer AZ too, so that may have been the cause). Also the front started to scallop around 5,000, and I think I as running it at 36 psi the whole time.
I am on Pilot Road 3's right now and would say they are awesome. Almost as much grip as the Pilot Power 3 (maybe 90-95%) and lean in is almost as smooth. I've got 5,000 miles on them and the front looks like new and the rear looks slightly broke in. I had some Pilot Road 2s before all of those and I hated those the most of any tire I've bee on. Going to try either the Pilot Road 4 next or the Bridgestone T30.
