Here's some information I got direct from Toyo on their Observe friction tire:
Thank you for your interest in our Observe snow tire line. The Observe line has been tested and meets the new performance defintition provided by the Rubber Manufactures Association as a tire suitable for severe snow conditions. Our engineers and an independent company also tested the Observe G0-2 (different patterns depending on size) against the Bridgestone Blizzak WS-15, here are the test results;

Toyo Test | Toyo | BS
Snow Braking | 4 | 4
Snow Accel | 4 | 4
Snow Slalom | 4 | 4
Ice Braking | 4 | 5
Ice Accel | 5 | 4
Size: 195/65R15

Independent Test
Traction-Medium | 4 | 5
Pack Snow
Braking-Hard | 4 | 4
Pack Snow
Braking-Ice | 4 | 4
Size: 205/65R15

5=Excellent
4=Very Good

We hope this helps.

What about walnut shells?

I agree..! I assume they mix walnut shells into the rubber coumpound to aid in traction, but people posting should explain what the heck they are talking about...
Being from So Calif, we don't buy a lot of snow tires...!

Coarsely ground walnut shells are mixed into the tread rubber. When the tread wears the walnut particles fall out creating lots of small snipes that aid traction on packed snow and water free ice. The tread pattern provides most of the traction on loose snow and gravel.

I find that both Toyo and Blizzaks are way too expensive. I have had excellent use from the snow tires provided by the Cooper Tire Company. I use four snow tires on the Subie for longer winter trips (FWIW - best snow car I have ever owned) and a set of worn out all seasons on the Buick Wagon to get to the park & ride lot and back. Worn out tires, a 4500 lb car with a 350 V-8 and snow can make for some wake up driving first thing in the morning.

They eat walnuts while driving on the test track and throw the shells out of the window to create more friction

Would it help to just throw a lot of walnut shells inside the tire casing before mounting it on the rim? How well do they stand up in a nitrogen environment? At slow speeds, can you hear them clattering arouind in there?

Yeah, That's a great idea! The unbalanced walnut shells rolling around will cause a shimmy which will improve traction!!!! Only because your max speed will be 4 miles an hour.

Hi Folks,
I have been buying and driving Toyo Observe tires for years, yes, they are the ones with the 'microbit technology' (aka walnut shell bits) embedded in the rubber. Bought my first set in 2006. We get a lot of 'black ice' where I live. Those tires have literally saved my life several times! We had 'black ice' the morning after I had my first full set put on a Saturn. It was a dark 0540 in the morning when I arrived at an ice-slick (empty) parking lot where I worked at the time. (It's a huge parking lot . .) I accelerated up to about 25 MPH and then slammed on the brakes. The car stopped smoothly, no skid, no problems. I knew I had a winner.

Then, I started putting the Toyo Observe tires on all of my vehicles. I see spending a few extra $ as no problem when my life has been saved several times by these tires.

Just found out today that Toyo has apparently stopped making the Toyo Observe tires. Nitto, a sister company, makes the Nitto NT90W, which apparently uses the walnut bits. But their line does not come in sizes to fit my current cars. Guess I'll have to buy a car that can take the Nitto tires! Don't want to give up my walnut tires!
