Hello,
I'm not sure how much you're looking to pay but we have sets of 4 as new wheels and tyres that we're selling at £299 (they've done about 10-15 on new cars before being taken off at factory). This really is a bargain as they come with new Continentals or Michelins on which are worth more than that on their own.
Here is my original post with the details;
