First of all, I'd like to say that I did not purchase these tires new. I traded wheels and tires with a buddy of mine when I first got my car. I put about 20,000 mi on these and had them for 2 yeras before I decided to get new tires.
I mainly used them for daily commuting but I did take a 2,500 mile road trip once. I live in western WA and we get alot of rain here. Considering these are summer tires I was really impressed. Though my car is AWD, I would constantly put these tires to the test on freeway off ramps and other hard corners. I was never once able to get them to slide. I can only recall one time that I hydroplaned a little while accelerating aggressively. It doesn't snow much in my area but I did drive in some snow a few times. As long as you're not trying to be Ken Block, these tires are not bad in the snow. They were good enough for my girlfriend (who is a less experience MT driver) when she had to make a 20 mile drive in snow.
These tires wore very little in the time I had them. In fact the only reason I bought new ones was because they were getting old and were starting to crack a bit. One of the tires got a screw in it and it ended up being un-repairable.
Overall, probably my favorite tires I've had to date. Great handling, great look, minimal tread wear, and the tread pattern looks great. I highly recommend these tires to anyone.
