The Bridgestone Blizzak WS70 snow tires are the latest in the line of high quality snow tires produced by Bridgestone. These Blizzak snow tires are basically an upgrade to the previous WS60 line which has shown to be exceptional for use on all kinds of everyday cars and minivans including the most popular models of full sized cars like the Camry, Accord, Milan, and many others.
This basic Bridgestone snow tire is really no different the best snow tires of the past decade or so. Other than technological differences and minor differences in features and design this tire is just another snow tire… except it's a very good snow tire.
Snow tires in general are like rain tires in that the tread on the tires are designed to provide extra traction in wet, snowy, and icy conditions. Tread patters are designed to project snow and moisture away from the tire's surface while the tread is also designed to make pointed contact with the surface to create as much friction as possible on icy road conditions.
Although snow tires are designed to create traction in icy conditions they are also typically designed to perform well as an all season tire making them excellent buys for year round use in northern climates. After all; in the worst of snowy conditions you would not only rely on snow tires but on heavy duty snow chains to keep your vehicle safe and square to the road at all times.
What sets the Bridgestone Blizzak WS70 snow tire apart from rain tires or even all season tires is that it truly is a snow tire first and an everything-else tire second. When compared to the Blizzak snow tire WS60, it's predecessor, this Bridgestone snow tire is built a little narrower and longer providing a narrower and longer surface area for the snow tire to come in contact with the ground.
This allows the tire to more easily cut through snow alit a knife and grip the ground. In the case of larger or wider snow tires there is more surface to touch the ground meaning there is more of a chance the tire will be sitting on a slippery patch of ice. When you shrink the surface contact area each point of traction you find is more significant.
In addition to the different shape of this snow tire the WS-70 Blizzak snow tire also has more deep grooves than the WS-60 and deeper tread patterns allowing for more traction. In addition to the changes in the tread patters the Blizzak WS60 tire also is designed with sipes or which are jagged groves which aid in traction kind of like cleats help a sportsman maintain traction on a field.
Basically this new snow tire from Bridgestone is one of the best snow tires on the market today. It was first released in July 2010 just in time for car owners to prepare for the coming winter. Some car safety studies have shown that nearly forty percent of winter related car accidents were attributed to 10 percent of the cars on the road which used "all-season" tires. If you want to be safe this winter then maybe buying a set of Blizzak WS70 snow tires is a better move than sticking to the all season tires you have used in the past.
