Just a word of warning for you guys on this scheme like myself. Got a 6 inch screw in my rear nearside tyre last week. In the tread and straight out the side wall /ubbthreads/images/graemlins/blush.gif Both rear tyres were at 3mm. National tyres are the only 'Audi approved' supplier of replacement tyres. So I went into my local place and 'asked' them nicely if they could replace them. They measured them at 2mm and got authorisation and replaced them free of charge /ubbthreads/images/graemlins/grin.gif However, they replaced them with conti sports and NOT conti sport 2's as per fronts. I queried this with Audi and their policy is to fit Conti's no matter what make was on originally. So if you have michelins, they will still fit conti's. The only exception is if you have Quattro, in which case they will stick with original make.
