I claimed off the council for my wrecked alloy / tyre about 8 years ago.
Took about 8 months with constant phoning / letter writing.
I eventually got all the money back but in that time I was running about with the spare on in case they wanted to see the damage in person.
Don't know if I could be bothered if it happened again due to the hassle but the more folk that badger them the more they are likely to act upon it.
If you do proceed, get pictures taken with a ruler measuring the depth, breadth and width.
This was part of my letter to the council!! The other pictures had my son with a steel rule showing depth etc.
http://www.potholes.co.uk/ has standard letters to send off.
