I only got 11,000 miles out of my Michelin PS2's over 3-4 years. The fronts are fine, still have half the tread left. I was going to replace all of them with something else but I found a new set (rears) of PS2's at half price so I just replaced the rears. I don't spin my tires either, the PS-2's are pretty soft. If I get 3-4 years out of this set I'll be happy. Right now the next tires I'm looking at is G-Force's but that's down the road.
