It's no Pilot Sport and beyond 15,000 miles is the equal or superior of any tire in the 15 " size. Some tires are softer in the first 5,000 miles or their directionality offers a little improvement till they wear in, but for a non snow all temperature [A/S] it's impossible to beat.
You know, my darn Yokohama AVS dB 225/60-15 (non S2) still have over half their tread at 28K. I have flipped them every 7K, but so far no problems, no feathering, and great in the rain.
This is the car that had the original Pilot Sport Michelins on it when I bought it with 26K 2.5 years ago. Drove across country from Brooklyn to Seattle on them, even passing the TireRack warehouse in Indiana with the Yokohama in the car because I douln't find any dealer to mount them. Duhhh. Michelins still had plenty of tread, but were cracked and aged from ozone. Mostly garaged, so UV was not much of a factor.
It will be interesting to see how they compare to new XGTH in a couple of months when they are together.
