I am not a big student of Avon tyres. Usually have used Michellins on the scoots. They were quite good. I also always seem to get a lot more miles out of them than other people, but I didn't ride at really hi speeds and bend corners except once in a while. The 2012 C5 I jsut bought looks like it has been ridden marder than I normally do based on tyre wear, but I am not sure what I should be seeing. How long do these tyres normally last? And no, they are not the horizontally grooved tyres I think you guys are talking about.
