I also posted this in the A8 section as well.

Let me first start out by saying that is is my dream car and it has exceeded my expectations. I am trying to find a tire that I can use with the factory 20" rims that are somewhat quiet and last more than 10-12 thousand miles. I started out with the factory tires, i think they were Pirelli's, I hated them. I then switched to the Conti's and they started out well, but at 12K, they need to be replaced and they got louder over time. I do not drive the car hard, but do about 50K miles a year for my job. There appears to be only 4 choices of tires. Anyone with a recommendation and experience with better results?
