I just got the new Bridgestone Blizzak WS60 delivered. 185/65-15. I took some close-up tread pics if anyone is interested. Once we get some snow, I'll add a review to this post.

Some things I noticed. There are now "brake boosters" just like the Nokian Hakkapeliitta RSi has. Look on the hind side of the tread blocks. Also, there's curious little grooves running perpendicular to the sipes. They're very shallow too, so I'm wondering what they're for. Just a manufacturing thing, like the little mold nubs?

The WS60 now has a directional, water channeling design which seems so common on winter tires (all tires really). My old WS50s were unidirectional and had no clear channeling for water and slush removal.

Thanks for posting the pictures. There is definitely some changes.

For reference, here is a shot of the WS-50

The siping looks REALLY shallow on those tires. Is it as bad as it looks? This has always been the downfall of Blizzaks. They lose the snow traction after the treads wear down below the siping.

The sipes are deep, just not all at exposed on the side of the tread blocks. I was wondering about that too though. I poked around with a small screwdriver a bunch and all the sipes go very deep.

The Tire Rack has their latest Winter catalog out, and in it there are preliminary tire test results. I'm assuming a more comprehensive article will be up on their website eventually. Here's the catalog. http://www.tirerack.com/images/pdf/ITwinter07.pdf

In the catalog they have 60 foot acceleration times on ice. (a hockey rink).

#1. Blizzak WS60 = 4.6 seconds
#2. Dunlop Graspic DS-2 = 4.9 seconds
#3. Michelin X-Ice = 5.2 seconds
#4. WinterForce Studded = 5.3 seconds

I know the Winterforce isn't considered a cutting edge tire, but it's still encouraging to see three modern studdless tires outperform it in this specific test. From what I've heard the Graspic DS2 has a new tread compund this year. In past tests I don't think it has done this well.

Well I have over 1,000 miles on these tires, and have been driving on lots of snow and ice lately. Thought I'd update with a review. My last tires were the Blizzak WS50.

Pavement:
The WS60 is a significant improvement over the WS50. In an effort to save treadwear I haven't pushed them too hard, but the difference is noticeable. Even with full tread depth, that squishy freeway wander is much reduced (after the break-in of course). Let's be honest though, these are serious studless winter tires, so don't expect them to be a "good" pavement tire. I do feel safer on the freeway with the WS60. The WS60 also seems to be more firm in compression (vertical loads). Driving over rough, broken pavement is a noticeable change over the WS50.

Snow:
I honestly can't feel a large improvement in snow traction. I'd say they are roughly the same, possibly a bit better. I need more testing time to be sure though. Keep in mind the WS50 was never a bad snow tire. What is improved is straight line stability in deeper snow. The WS50 would noticeably wander over roughly 25mph. This seems to be almost gone with the WS60. Little corrections are certainly required in deeper sections, but it feels much better. Confidence is up!

Ice:
The above TireRack tests seem to indicate the WS60 is a far better ice tire than the WS50, so I'll have to take their word on that. I haven't driven on glaze ice on the WS50 in a long time, since we don't get ice like that very often in Minnesota. We did have a late night of pure ice a week ago, so I did test the WS60 for a short while. While it was definitely slippery, and wheelspin was plentiful, I never felt out of control. Nor did I ever feel I was ever gonna be stuck. Keep in mind these were conditions that only a high-end studded tire would have done well in. Overall I was pleased.

Noise:
I've never experienced noisy winter tires as some describe. The WS50 was quiet, the WS60 is quiet.
