Hmm should not be torn away, but just chipping which is still not too bad, like my F1-D5 or PS3.Well, if the compound is too soft, it also means that the tarmac is also like sort of tearing away the rubber compound as you go.
Sounds like a really good tyre. You are using them on all four wheels?

Yes it's an excellent tire in terms of performance. I'm using CSC5 at the front but the older version CSC3 at the rear which is also still a very good tire, just a bit lesser grip.
