A First Look at the Blizzak WS70

We're in the middle of our ice rink test of the Bridgestone Blizzak WS70. We actually take our BMW test cars to a local ice hockey arena and perform a variety of tests ranging from acceleration, braking, and cornering on ice. I just came back from testing the WS70 alongside the other three tires chosen for this comparison -- the Continental ExtremeWinterContact, the Michelin X-Ice Xi2 and the Dunlop Graspic DS-3 -- needless to say, I was surprised with some of the results.

The Blizzak WS70 performance was as expected. In past ice tests, the Blizzaks have shown outstanding ice grip and braking, and were the only tire to actually squeal going around the corners, always looking for that extra grip to glue the car to the ice. This year, however, Continental has upped the ante with the ExtremeWinterContact. While I still think the Blizzaks have shown better grip and traction, the Contis are a very close second and they too gripped to the point of squealing going around the corners. Unfortunately for Michelin, the Xi2 did not perform as well as in past tests, specifically in cornering and acceleration, but were the ones with the shortest stopping distance during braking. The Dunlops simply couldn't compete with the other three tires, but are definitely much better on ice and snow than any all-season tire.

Video and test results will be posted on the website in a few weeks. In the meantime, check out last year's test here.

Here in Tacoma WA. we had a snow storm. I was kind of disappointed that the snow wasn't slippery. Then I noticed other cars were having trouble maintaining traction. The fact is the snow was slippery, the Blizzaks WS70 just have very good traction in the stuff, better than my studded tires had. The tires are very good in snow & even on our now icy streets they are performing very well. These tires are on my 09 Mercury Grand Marquis, & for it to outperform the front wheel drive cars with these tires says something. I notice other cars were having trouble going & even 4x4 were having trouble stopping & I wasn't having trouble stopping. I have the Blizzaks on all 4 wheels is why I wasn't having trouble stopping. On a scale of 1-10 they are about a 12.
