Your wife had the chance though and she said to do itIf I had the chance I would have said thanks but no thanks,
£70 nearly pays for a new tyre and if they measured it again they’d get a different answer.
Unless the tyre is obviously wearing unevenly, don’t touch it.
Out of specification, don’t make me laugh, if they want I’ll sign a concession lol.
They wouldn't have held a gun to her head, she made the decision to get it done on her car. What you would have said is irrelevant really.
I got a call from the local STS when getting tyres on my wife's car about alignment. I couldn't picture the amount it was out by in my head and whether it was worth doing or not so I told them just to do it. Did I waste £60 on something that wasn't needed? Probably. If I do that every time I get tyres on her car it will be less than £10 a year added to the running costs, so ultimately, who cares.
