A few months back whilst looking for a replacement tyre for the car I ended up on a site that allowed me to enter my postcode and the size of my tyres and it came up with a list of the cheapest within a set mileage. I thought that it was on the AA website, but I can't find it now, anyone else seen anything like that?

Failing that, any personal preferences?

My last one was from an F1 autocentre, who seemed fine enough.
