We mounted up the set of Coopers on my stock aluminum lariat wheels, set at 53psi front and 45psi rear, same as the other two sets.
What we noticed right away was the Coopers are quieter than the Nokians, and did ride smoother on pavement. They did feel a bit squirmy at 80mph, the deeper tread and less contact area with it's two large channels for slush we believe contributes to this. They did not create any feeling of nervousness, just a bit more driver correction was needed to maintain direction.
Braking from 80km/h was close to the W965's for distance surprisingly, but shorter none the less by about 1 truck length.
Flying around the sharp right corner did produce a slide at 65km/h, close to what the W965's did.
On the icy hill they did not bite as well as the Hak LT's, needing a few attempts to make it up. They did spin out, and when this happened they did start to slide backwards until completely off the throttle, much like the W965's.
Running through the snow, the Coopers did work better than the W965's. They did manage to get moving once stopped on a snow covered section, the same spot where the W965's failed to get moving without 4wd.
We managed to run up the hill and fully turn aroung in the same area the Hak LT's did, all in 2wd again. It did require more effort to maintain speed, and you did have to pick your line through the snow better than the Hak LT's, but they were a improvement over the W965's. Not as much as the Hak LT's but an improvement none the less.
Braking down the hill showed braking distances marginally shorter than the W965's. From 50km/h they stopped an average of 8ft shorter. From 70km/h, we varied 9-11ft, depending on what line was picked to run.

All said and done, this is how they ranked.

The Bridgestones have thier place in the winter tire market. Someone that doesn't see alot of snow or ice, or can't stand stud noise of dry sections of pavement. These tires will give you better winter traction than any all season or all terrain on the market. I was very happy with them, and ran some ugly days without worry. If you don't want studs, these are the best on the market. If you're running anything lighter than a 3/4 ton truck, go with a different tire. These tires need some weight on them, the more the better.

The Coopers IMO were somewhat of a dissapointment. Not because they were a bad tire, they did increase overall traction compared to the W965's. The deeper/open tread did give it better snow capabilities, and the studding did improve ice traction, just not to the degree I expected. These tires are a marginal improvement over the W965's, and I believe without the studs the W965's would of ranked 2nd, not 3rd overall. I believe a different rubber compound would help these tires. They seemed to have the right mix on paper to come out #1, but are a distant 2nd in real world testing.

The Nokian Hak LT's are a fun tire to run. They make you want to find deeper snow, more ice when you go out for a drive. They were shipped straight from Finland, all I can say the Finnish know thier tires. 10 months of winter evety year I guess they need to develope a good tire.
I've ran Nokians in the past, these are the best to date.
The braking traction was surprising, the ice traction on the hills dropped my jaw, and cornering/lateral grip, a league of it's own.

If you want the best winter traction on the market today, find a Kal-Tire if you're in Canada. Ask for the Hak LT, and stud them up. Anywhere else go to

You can search for dealers globally there. I'd put these LT's against any light truck tire on the market, they're that good.
Almost forgot, traded my W965's, I kept the Hak LT's used on the test.

I have also put in a request for next winter of a new Nokian tire for the wife's Windstar. It can be seen here http://www.nokiantyres.com/index_en.html

The Hakapeliitta 4. I think this is going to be the best winter tire to hit the market, ever. Get in line early if you want yours!
