Update: I now have 9500km's on the Continental tyres and are still working well. I suspect they have another 500-1000km's left in them yet. They have a feature called Grip Limited Feedback which I can attest to, when you get to the edge of the tyre they slide in small amounts to let you know there at the edge.
I was only getting 9000km's out of the Pirelli front and 4500-5000km's out of a rear so I'm at least 1 rear tyre ahead.
