Now then. I wanted to swap the tyres on my car. Front wheel drive car so the front is getting thin a bit and both tyres have maybe 3k miles left in them. Both of the back ones are more or less untouched with plenty of life left in them. So I suggested to swap the front ones with the back ones. However was told at the garage not to do so. The argument used were:

You need more traction at the back so better tyres need to stay in the back.

Any of you work in the garage and can confirm that for me? I have never heard that argument before and remember swapping tyres from back to front before.
