We have a few Subaru Forresters at work and I noticed that one of them had the tyres worn to the canvas (great advert for us

). I made the woman in charge of these vehicles aware of it and the motor was whipped down to the local tyre centre for new rubber.
When it came back I realised only the front tyres had been changed

. I was under the impression the tyres should be changed as a full set? The guy that came back said the garage told him they didn't need to as teh centre diff wasn't of the type that required it
