They are good tyres. I have been using them for quite a few years now. The only things against them are standing water/aqua planing as the grooves are small and also the price. I had a chat with the guys on the BMTR (Avon resellers) stand at the Autosport show to see if they could do something about dropping the price a bit as the mould must have earned back it's cost by now. Here's hoping as I will need some new rears soon.
Cheers
