2013 Audi A6 Tires

I live in Maine and need all-season tires that can withstand its climate with rainstorms, snowfalls, and everything in between. I have had these on my Audi for about a month and what I can say for now is that they provide great grip even in heavy rain, so my car never hydroplaned or wavered in any way. On the dry road, they also work great, but are a little bit noisy as for me. can't wait for snow to see how they will perform.
