Every damn Avon Storm I've had on either SV has ended up getting a puncture, as theres a stupid loading bay at the end of the street.
Every rear Avon Storm I've ever had has just gone past the required depth for a free tyre under their garantee....SODS LAW
The first rear I had was a Bridgestone....couldn't kill the thing for toffee, had a big hole in it, was square as a square table....eventually after 10,000 miles or so, it gave up!
