You will not have as much traction.
Studded snow tire.
They are metal Pins that are stamped into a tire and they help you get more grip on snow and ice. :D
mostly, its all ice & snow, but there are some mountains with brown and (surprisingly) some green! which of course only happens in the summer time
Snow and ice
Why do you assume there is ice underneath the snow? In most instances there is no ice under the snow. The narrow tire can get down to the pavement easier than a wide tire.
It is a tire with a less aggressive tread since there is no snow or ice to worry about and a smoother ride and a longer lasting rubber compuond. They will also have good wet weather driving characteristics.
No wide tyres or better because the give more grip Actually wider tires don't give you more grip in snow. They simply allow more snow to pile up in front of the tire. On Ice or snow pack a wider tire will provide better grip but in deep snow the thinner tire works better. Chicago winters taught me that.
About 3/4 of a billion years ago ... the ice-ball (or snow ball) Earth, when the entire planet was covered in snow & ice, the seas frozen.
Presumably snow, but in places like Antarctica they have snow and ice year round. Therefore, I am unsure about the exact answer to this question, but I stick with snow.
The very best reviewed snow tire is the Michelin X-Ice Xi2 but it is expensive. The very best budget snow tire is the General Altimax Arctic and is just as good but noisier and rides a little rougher.
Snow crystals form when water vapor condenses directly into ice. This happens in the clouds.
Cable tire chains are also known as snow chains, they are devices fitted onto the drive wheels of vehicles to provide friction or traction while driving through snow or ice.
