The snowtech 2 is basically a rebranded Conti TS800, with minor modifications (2 added water channel).It is built in the same factory by conti... Grip is phenomenal in all conditions, basically you get a conti wintercontact at half price. Very low road noise,good consumption, wear is expected to be average. At the 2013 Autobild winter tyre test it finished 4th and it had the shortest stopping distance in snow!!!
I bought these as a budget option from my garage. They ended up charging me Michelin money for them, but that's beside the point. They're an overall good tire. The grip in the dry and wet is good. As well is the grip on snow. The handling inspires confidence. Road noise isn't too bad in my opinion. You hear them, but not annoyingly. I can't say much about wear yet, since I have had them for just 5k km.
Bmw e90 320d, terrible on wet and tyres are brand new, havent driven worse tyres on a wet surface, never buy again. I am concered but can't afford to changre them.. before these I had nexen which were much better but changed them becouse of road noise..
