Depends on how you ride. If a set of PR3s only got me 8000 miles I'd be a bit irritated, if it only lasted 4000 miles I'd be furious. My last set lasted 12k miles. I don't ride as hard as he tends to though, but I do beat on them pretty hard from time to time. They are phenomenal tires and require very little to get up to running temps. Come to think of it, I never worry about it. I just get on and start going. The end-of-life characteristics are nice too. Even when they're going bald they slip just enough to say "Hey, I'm done.." but they still have a surprising amount of grip. The only time I've had one slip on me outside of being past the wear limit was on a cold, dusty blacktop road that doesn't get much traffic while going around a bend over the crest of a hill. Can't really expect much from a tire in that situation anyway though.4000? thats not bad. And they are grippy enough for wet/cold/crappy situations?
Been a month, wonder if he made it
