I claimed for my alloy a couple of years ago and got paid full for my wheel. I was glad about that, and also I was glad I took photos too as the within a few days the council was there filling it up with tarmac. Photos don't tell lies especially with time and date on.
Providing your wheels and/or car isn't modified you have a case.
Persistencey is the key however!
Hope you get paid for your wheel. GOOD LUCK
