I've just put Dunlops on mine, it was wearing 2ct's, but the front was shot to the edges, but worn unevenly in the centre, the back was at 50% from edge to edge.
I moved off ct2's because the wet weather grip is not good enough for me, the Dunlops give me a little bit more confidence in the wet.
I don't normally go out in the wet, but the last meet up in Wales was pretty much wet all day the first day and the back was spinning pretty much every where no matter how carefull I was.
The last ct2 on the rear was a 180 and it lasted 1800 miles.
