In a word: Admiration. Fantastic, grippy tires, great under braking wet or dry. I lazily allowed the rears to get to a tread depth of 0.5mm(being optimistic)and despite being virtual slicks, they never once stepped out of line, despite me pushing on at a fair old clip.
I replaced them instantly (for legal reasons!) with near new Champiros that had come with the car; first trip on that wet and twisty road and despite pussy footing, the back end was stepping out all over the place.
I'd estimate my HP(rears) were legally shot at 20,000km, but given the supreme grip and the confidence they engendered, I was more than satisfied.
