Replacing Tyres in Pairs/Singly

Hi Martin,

Replacing tyres - and Fuel Economy

I think there was a thread about this a while ago but I can’t remember the outcome. I had to replace a rear tyre today and went to a recommended local garage. They insisted I would have to replace both of them, although the other one was virtually new. On the upside, their price was a lot less than I had expected and they replaced a scuffed wheel trim (don’t ask!) unasked and at no charge. Is it really a requirement to replace tyres in pairs?
