Hi!
I used few kinds of winter tires in time. No 1 I think it is Nokian Hakkapeliita 6 (or 5) on both FWD and AWD very good ones. You can feel the difference right away. On the FWD vehicle I used to have Yokohama normal ones and then Verdrestein directionals (v shaped pattern). Vedrestein were better but nothing like Nokian. Then after buying the AWD for my wife I got a parking spot under the building I was living in and she always got out regardless of how bad was the uphill exit from the parking. Ice, wet show, dry snow, deep snow (~20 cm). At times she was the only one able to get out in the morning from that parking.
One time we went to a cabin in the mountains and it showed a lot over night building it up to the top of the bumper of my Toyota RAV4, about half the tire diameter. I got out of there in few long minutes. Had to back up few times to get some momentum to push forward. All the others had to shovel their way out about 10-15 m and they had AWDs too. I think my Nokians had their part to this performance.
Same winter my neighbour slide back trying to get out of parking and she damaged her car, a Honda Fit. Tires, some Motomasters directionals, loose grip exactly close to top of the hill at street level. She had the presence to press the button of her remote control to open the garage door while she was slowly sliding back while car whells were spinning foeward and she just lost her left side mirror. Other neighbours had to fix that door after finding themselves in same situation (sliding back into closing garage door). She asked for my help and since the new Nokians were too expensive for her she got a set of used Hakkapeliitas (7 or something, better than mine) on internet. No 6 was still visible on pattern so they were above 6mm tread. Well she never had the random excitement getting out of parking after snowing or ice rain again.
When I got my RAV4 it came with Bridgestones. Then I had some Michelin X ICE used from a neighbour that sold his car. Bridgestone were better on snow and Michelins better on ice. These were my best winter tires until I got the Hakkapeliitas. Nokians are better than those on both surfaces. They are also noisier on dry but not by much. If you plan to use them summer time too, don't. They will loose some of their grip on ice next winter.
Michelins are the best as summer tires or rain tires if you buy the directional ones.
Other tires I had over time on a FWD vehicle were some Continentals directionals too. Better than Yokohama and Vedrestein but when they were less than half something happened and they loose their ballance to the point I had to replace them.
Now I got some Nokian WRs since I was unable to find the Hakkapeliita. Hope they will perform next winter.
Is not first time I got WRs. I had 2 new ones on the front axle of a FWD VW Golf Variant. Somehow one of them got some side bump and got unballanced, later developed some sort of cut about 6 cm long just beside the rolling pattern while rolling on dry about 10 degr C. Had to replace that one on road. I managed to get out of highway and make it to a shop after inflating it twice with my small portable 12V compressor.
While I had that tire car was driven by me, my wife and my sister. (I can't say for sure if tire was abused or not.)
This is a second chance I give to WRs based on my expecience with them. I can say, I think they are thinner than Hakkapeliita, also lighter, maybe an inferior kind. I hope those will do better than previous ones. I will still use the "survivor" mounted on rear pairing a Fulda (only one that had about similar pattern and thichness to my good WR in that shop inventory when I had to replace the failing WR. When it happenend I already had them switched to rear axle since I was unable to use them on front due to vibration given the unballance. I was hoping to make it to the end of winter, one month and a half, but it didn't happen. Tire gave up after about 1000 kms on rear axle).
Oh! One more thing. One of my friends bought some asian tires that had a pattern identical with Nokian Hakkapeliita. Don't get hooked into that. They start to get some strange chipped wear on rolling pattern and one of them got a side damage by a splint of wood!!! How weird is that! He had to replace that one. Guy was unable to fix it.
Grip on snow was compared with some average all season ones even the mountain and snowflake was displayed on them.
