I've had these tires going on their third winter on my Tiguan. I like some aspects of them, but am a little disappointed in other aspects.
First, the good:
These tires have great winter traction, particularly in ice and snow. I feel confident in slippery conditions, they are not particularly mushy, and have decent wet and dry performance as well. There is no excessive tire noise. I bought these new the same time a bought another new set, for the Toyota Sienna I had at the time. The van had the outgoing Continental ExtremeWinterContact. I found the performance of the two tires to be quite similar, but I note these differences: on particularly slippery surfaces, the Winter Edge would kick the ABS on for the last foot or two of stopping, where the ExtremeWinterContact would not. The opposite happened starting off on these same slippery surfaces, the Winter Edge held much better at the initial start from a stop, where the ExtremeWinterContact would have a bit of slippage. Otherwise, I would say performance of these two are quite similar.
Now the bad:
After the second winter, when taking the tires off in the spring, I noticed chunks of the tread had broken off or were breaking off on the front tires. The ambient temperatures by the time I removed them was hitting 15 Celcius, but they were also city driven, and not highway driven during that period.
An additional point, which I will not categorize as good or bad, is that these are made in China, albeit at an entirely Cooper owned factory (that they took over from a partnership with Kenda). This may be a factor for some people, but knowing it wasn't a third party's factory gave me enough of an assurance to buy these tires.
I would say I am not likely to buy these tires again, simply because there are so many other good choices out there, and this is the first set of winter tires I've had with chunks coming off. That said, I may be tempted with a killer price to offset what looks like a sign of shorter tread life.
