A co-worker of mine recently relayed the following account of a road trip he took last winter. As a sales specialist at Tire Rack, he had great experience testing the Bridgestone Blizzak WS60 and was able to compare its characteristics to the WS70 he installed on his vehicle. Here is his story:This past winter, I embarked on a 1200-mile (round-trip) drive with the Bridgestone Blizzak WS70 at full tread depth. With the tires installed two days prior to me leaving, I thought this would be a great opportunity to provide a comparison to the previous generation, WS60.
Leaving Indiana, there was a huge snowstorm that made me glad I had a new set of winter tires. Throughout the state I was able to avoid approximately four or five accidents, one of which was directly in front of us and quite scary. The traction and control in the snow was great, but not a huge difference from the WS60.
As we entered Kentucky, the temperature was still cold, but the roads were dry. With the opportunity to test the tire's road noise, I noticed a big improvement when compared to the WS60. I also noticed that as I hit patches in the road with bumps, that the handling was better as well.
Coming into Tennessee, the temperature was anywhere between 30 and 50 degrees Fahrenheit. The roads were in great condition, as I felt they were smooth and without potholes. I had flashbacks of driving in the Black Forest along the Germany and Austria border, except I was not in a Porsche, rather a 2004 VW Jetta 1.8T manual transmission.
After reaching my destination, I believed the tires did pretty well! I did notice some delay in the "switchback" from one direction to another in 'S' curves but overall very impressed with the Blizzak tires; especially considering how hard I pushed them on a stock suspension with 12/32nds tread depth. Once I was anchored in a curve, they felt confident and stable. I am very impressed, and was able to see all major winter conditions in the first week of driving, which allowed me to make a great comparison. And I must say these are now my favorite winter tire.
