Just wanted to point you all to etyres.co.uk. I have just used them to have two Falken 452's fitted to my front wheels. They come to your workplace or home, and charged me £ 194.40, incl new valves, balancing and disposal of the old tyres. They even come with a lifetime puncture repair cover.
Given that mytyres.co.uk charge £ 181.60 just for the tyres, I think it's a fantastic deal. The Falken's aren't listed on the etyres website, but you can phone them and they'll get them in. Very friendly service all round.
