It maybe still the same now, erm because right up to the time I erm retired we, we had on occasions to pay for the residual value of a tyre, perhaps a bus had been in accident and the tyre had suffered damage which it wasn't possible to repair it or retread it, perhaps a hole had been pierced through the wall, they scrapped that tyre and we had to pay for the residual value, mind you being in accident we could then claim it off the insurance company but, so right up to the time I retired that's how tyres were paid for.
