This morning my girlfriend drove to Bolton from Newcastle and in the last 5 mins of her journey she noticed that the ride had gone harder and suspected that she was losing air pressure. She drove to Kwik fit ho said the tyre was ruined and so she had to get it changed. I spoke to the guy there who said that there is no hole in the wheel apart from the inside rip on the tyre wall from where she had been driving it. As the car is only a few months old, should I take the tyre back to Audi? I know tyres are not covered by warranty but surely a car that is a couple of months from them should not have an issue? Also there is a squeeking noise coming from the other wheel and dont understand if its a disc or brakes that are squeeking.
