They are cheaper than most, and you can arrange fitting locally. Get rid of the run flats asap, they are horrible!!
Michelin PS2's are the tyre of choice it seems, although there are a few with Dunlops and Conti's
Personally I love the Goodyear GSD3's, but they have stopped making them now, so they are like rocking horse s**t to get old of.... not ideal if you ever need one quick!
Just had a look and they have a special offer on the Dunlop SP9000's. Not sure who has them on here though.
