I hope he fought that. Unless they are of the wrong size or rating they'd have no chance of getting away with that, they would need to establish that the tyres caused the accident too, in other words if they accident was simply that the reversed into somebody in a car park, it would be difficult to prove that the tyres caused the accident. Consumer law is heavily biased towards the consumer these days.
