Just been on Kwik Fit's web site on the look out for some new tyres. They have a price calcualtor that recognises yoyr car type so you don't have to read out any strange numbers off the side of your tyre.
They are doing on-line quoting. Pick the tyres you want. If you need two there is a good discount depending on the tyre. If you need four there is a major discount. 4 individual tyres for my beast would have been £640. Bought together they are £450.
Once you get the quote, print it off and take it into your local branch and they will honour it!
