I think most insurance companies want to keep their customers, and if they treat their customers like trash, they will lose customers. I've been with the same insurance company for over 30 years, and I've NEVER had an accident that was my fault. I have made some claims though, but only for things like a chipped or broken windshield and minor chips on the front facia from being peppered by road debris and on one occassion a retread that flew off a truck in front of me on the highway. They would never have the expertise to know I modded my car with the Predator and a t-stat, nor would these things have anything to do with an accident. If someone steals my wheels, the same thing applies. It doesn't matter if they are the OEM wheels or if I bought aftermarket ones. A car MUST have wheels to drive, and insurance covers replacement costs (up to cost of OEM wheels, unless you notify insurance of mod), providing you have receipts.
