I have tripple treads on one of my cars, but I haven't had them in winter yet. They have about 9k miles on them and no complaints so far. My mpg went up 5miles after putting them on my crv. They are pretty quiet and seem to be pretty decent for highway driving. I know a lot of people are fans of blizzak tires for winter time, and just swap them out in summer. I've also had michelin hydroedge tires on my car for year round, and they worked well. I put about 20k miles on them and went through 2 winters on the 7thgen. They were SOOOOO much better than the stock 7thgen tires. They were great in rain and actually pretty impressive in snow as well. They weren't cheap, but neither are the tripple treds. I like the tread design on the hydroedge tires too.
tire rack had the best price on them when I bought them before.
