Out of 19 sets of tires I've had on my bike, this is the only time I've ever had a front wear out before the back. They are Pilot Road 2s and I just bought my second set of them.
These are also the first tires I've ever had that exceeded 6000 miles of wear (may get 7000 or more on the rear) and the front is the first that did not feather noticeably.
They are great in the rain, but a little loose in the dry compared to sport tires. I ride pretty sanely, so the lack of ultimate cornering traction is no big deal for me. I kinda like they way the rear predictably steps out under power, to be honest...
I like them.
