I don't claim to be an expert! I put these tires on a Nissan Almera and then drove them from the North Caucasus all the way to Hong Kong in the middle of a snowstorm and another snowstorm. It does an outstanding job of keeping the road clear of snow (I reiterate, I'm not an expert, but in contrast with what used to be (sadly, I can't remember the company) keep the road confidently), and I have never once regretted the money that I spent on it! I believe that when I get my next car, which I hope will be soon, I will put these tires on it.
