I have used up 4 sets of PSS in the last 8 months, and I can't emphasize how awesome these tires are. In between the 4 sets, I used two sets of RE-11s, and the PSS beats the RE-11s in everything except treadwear. The canyons I run are very abrasive, so I only get 3k miles per set of PSS, and I got a little over 4k miles on the RE-11s. But the response of the PSS, and the stability was way above the RE11s, and grip was slightly higher as well. I won't be buying any other tires, michelin really did an awesome job of these tires!
