I just put a pair of Hankook Ventus K104's 225-40-18's on the front - so far so good
Unfortunately this change was necessitated by a bulge appearing in the sidewall of one of my Michelin PS2's
I've still got a couple of virtually new PS2's on the rear
The guys at the tyre shop recomended the Hankooks as they say they perform well and were a lower price - it will be interesting to see how they wear.
