These tyres are like Velcro to ice and snow. I live in the South West of Calgary, which is very hilly, like Bow and Sarcee Trail. These Bridgestone WS70 tyres perform very well indeed and I have great confidence in their hill start, accelerating, cornering and most importantly stopping. I have over 25 years of driving experience from Europe, as well as here in Canada and I must say that these Bridgestone WS70 tyres, perform very well indeed. I would never dream of driving in winter without them. Any negative comments about the WS70, should be disregarded. Remember, the WS70 are dedicated Winter tyres, they are not for use in Spring or Summer and should be removed once the temperatures start increasing over the +7c range.
