I don't believe anybody is required to use snow tires. In fact, some states recommend that you don't use snow tires unless the conditions are bad due to the fact that they can damage/wear the roadways.
No
Snow tires!
Both Winter and Snow tires have a more aggressive tread pattern and are made of a softer rubber that grips better in cold weather. I believe that snow tires have a still more aggressive tread pattern than winter tires.
Snow tires prices varies from brand to brand, ranging from 60 dollars to 200 dollars per tire. They are more expensive than regular tires. They do have more grips than regular tires, because they have a different rubber composition.
Yes, that's a reasonable swap.
unfortunately the coeficient of friction between rubber tires and packed wet snow is so low that the inertia of the vehicle allows the vehicle to slip on the snow. Deeper snow or snow tires will increase the friction slightly and allow you to move in the direction of your choosing.

Depends on the weather conditions you will be driving. Winter tires provide noticeable increases in traction, control and breaking distance in ice and snow. If you live in an area where you see much snow and ice in the winter, then snow tires are highly recommended Not only would they increase your safety, but will also reduce your chances of getting stuck someplace! Not for nothing some provinces in Canada make it mandatory to use winter tires in winter. Snow tires are a low speed type of tire, and provide a rougher drive at high highway speeds. Snow tires can be noisier. If you are driving in a location where you do not see much snow, you may also want to consider all season truck/suv tires.
Directional tires are ideal for hard surfaces in good weather conditions. The best tires for driving in snow are snow tires.
No, Yokohama has manufacturing plants in both the US and Japan. Unless you are importing them they would have been manufactured in the US. Also, weather only really effects snow tires and other specialized tires. Snow tires will wear out quicker in warm temperatures because they have more rubber in them than normal tires.
In some places where it snows alot you have to buy snow tires. So if you have snow tires then yes you can drive if the snow is 8". But if you don't want to buy snow tires, you can get a chain and wrap it around all of your tires.
Fat tires are best in snow.
You can install 4 snow tires but it is really not necessary. Only install the snow tires on the drive wheels.
yes, AT "all terrain" tires are MS "mud and snow" tires.
If you drive in snow you have to, regardless of the vehicle make. -The snow tires are your link to the road.
Snow tires cost slightly more than all weather tires. The actual cost of the snow tires would depend on the brand, style and size.
From what I know, they probably do not because snow tires have special pins build into it for gripping the snow/ice. It depends on the type of tire you are actually going to buy but generally mud tires are more expensive than snow tires.
