If you are visiting in the winter it is probably a good idea, because sometimes the snow is quite deep, or it is icy.
If you are visiting in the summer- please don't waste your money on snow tires! There won't be any snow.
No
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.
All weather tires are not required by law but it is a very important idea if you plan to drive through snow. I would also recommend Snow Chains if your in a large snow area.
In Canada, studded snow tires are typically required to be removed in the spring, usually by March or April. This timing can vary depending on the province or territory, so it's advisable to check local regulations for specific details. Studded tires are designed for winter driving conditions and can wear down pavement when used on bare roads, which is why they are typically not permitted during warmer seasons.
Depends where you are, what tire and wear. Here in Canada, many people sell used snow tires and you can buy a good pair with 7-8mm tread for 50-60 .
Unless they are studded snow tires (which have become extremely rare) there is nothing keeping you from using snow tires year-round. Many state governments have limitations on when studded tires or tire chains are allowed to be used, or are required. Contact your states' Department of Transportation for these guidelines.
Directional tires are ideal for hard surfaces in good weather conditions. The best tires for driving in snow are snow 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.
Yes, studs can be removed from snow tires.
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.
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.
