If you own a 2003 Audi A6 4.2, you know the original tires are no longer made, and there are no replacement tires from any manufacturer in that size. I have four new tires that are the original make and size, Dunlop SP Sport 5000 Asymmetric, 235-50-16. I bought four extra tires two years ago and put them in storage for future use. Unfortunately, my car was wrecked and I no longer need the extra tires. Completely brand new. $175 each.
