Look up the difference between static friction and sliding friction and you'll understand quite a bit more about how your car handles in the snow.
Snow doesn't have static friction. It's fluid like sand. This is why snow tires have very deep grooves in them.
If you could rely on static friction in winter, then winter tires would look exactly the same as summer tires. Tire engineers know this, and that's exactly why snow tires look nothing like summer tires.
The above is a summer tire. Notice how flat it is and how shallow the grooves are. This tire uses static friction and large surface area. The grooves are mostly parallel to the direction of motion so water can flow around the contact area rather than causing it to hydroplane.
The above is a winter tire. It has deep grooves to grab and throw snow. It even has little grooves. Every part of the tire has grooves. Whoever designed this tire believes snow moves, and that the tire should be able to guide where the snow is moving when it does move.
This is a sand tire. Sand is fluid and it has no static friction. The only way a tire can propel something in sand is by displacing the sand. By pure 100% coincidence, a sand tire looks a hell of a lot like a snow tire.
lol. Are you fleabag's alt account? He said he could design a better car than a Korean car engineer can, and now you and a few other people are saying you can design better tires than a tire engineer can. Those stupid engineers at Michelin and Toyo with their fancy degrees and decades of experience honestly think snow is a fluid-like material that is most effectively dealt with by treating it as if it were similar to sand or mud. If they just came to the Anandtech garage to confirm that snow is, in fact, similar to paved road then we could have avoided such a silly mistake.
Those idiots at Michelin also should have asked Toyota what is the best way to deal with snow. For the past 100 years or whatever, Michelin and their material engineers have (incorrectly) thought that snow should be displaced and that snow tires should have deep treads with zig zag patterns. Obviously that is wrong, obviously. The boys at Toyota have done it again with their ground breaking engineering skills. They figured out once and for all that we should rely on static friction to move a vehicle on snow, and this is why the traction control they put on all Toyota vehicles prevents the tires from spinning and completely eliminates the point of a snow tire having deep treads with zig zag patterns.
To get perfect traction in the snow, you should get rid of your winter tires and use summer tires. The summer tires have big slat spots with shallow treads which maximize static friction on snow. Using anything other than summer tires on your minivan means you hate your family.
