Hi I have a problem with all four tyres wearing on the inner side walls, causing them to wear thought to the beading after 26,000 miles. Tyre wear across tread is even all the way across with 3mm of tread left on all four tyres. Audi have told me there is no known issues and have put it down to steering alignment. independent alignment check before Audi had it in, stated it was all within manufacturer settings. Has any one else come across this
