What are the best high performance summer tires for the 2013-14 S6 and the best high performance all season/winter tires? Any opinion on the stock tires?

 

Check out tire rack.com. They have all the info you will need to make an informed decision.When it comes to tires, i feel it's a matter of personal preference and will be difficult to gauge what one is looking for. For instance i find i don't want to spend more than $300 a tire on my S6 and no matter how great the stats are on a particular tire, if it's over my price point, it's a no go. Tire rack has all the stats like thread wear, firmness etc. So i'm not saying you should buy from them, but it's a great place to go get your homework done. Lets know what you decide to go with. Fyi, i have bridgestone potenza on mine now and they are just fine.

 

My all seasons recommendation is Michelin Pilot Sport A/S 3. I've put 8,000 miles on them in warm and cold weather climates including light snow. Excellent performance and tread wear thus far.
