I bought these to put on my 2010 Q7 TDI, witht the s-line package these were one of the only tires available NOT summer tires. Many of the reviews say the mileage isn't good, but I have almost 50,000 miles on mine, given those are a lot of highway miles, but I have traveled all over the U.S. and done a lot of mountain driving. I have traveled the logging roads in Idaho, through a snow storm up Mt. Hood, through snow storms in Colorado, through snow up mount rainier, across Glacier National park(until the road was closed) and even been down some jeep trails with them. They aren't to the wear bars yet, but are getting really noisy and keeping them balanced is a problem now.
I have used these year round since install and will get another set. I rotate and balance my tires every every 6 months or 10,000 miles being an all wheel drive(a must if you want nay mileage out of your tires).
