I'm on my second set of PSS tires now. I absolutely love them for a good all around summer (and Cali winter) tire. I'm running staggered, but my first set still lasted me 20K miles. The fronts actually still had some good tread left when I swapped them out, but the rears were well past being legal at that point. I definitely got the advertised 15K out of them before the rears deteriorated to slicks over the last 5k miles or so. Once the rears get thin, I tend to spin them a bit more which makes them go all that much faster than the fronts. These are the first tires I've ever had on my G that didn't wear the front shoulders off prematurely, so big props for the massive outer shoulder tread blocks on these tires; they definitely work!

That 6K that you got out of your tires was really out of whack though. Something had to have been wrong there.
