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.
Snow tires cost slightly more than all weather tires. The actual cost of the snow tires would depend on the brand, style and size.
Practically no. By the time the studs are worn out, tires are too worn for you to install new studs and even if you could, the cost of replacing them would be more than the tires are worth.
They are very little different. The tires are much more important and real snow tires are far better than all season 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.
More than narrow tread 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.
SUV tires do cost more than car tires. There is more material used in the bigger SUV tires. Keep an eye out in the newspaper, sometimes you can find a sale on tires at places like Big O Tires.
Michelin makes many different tires and they do cost more than other brands, but are well known as excellent tires for grip and mileage.
Driving in the snow on 225/50/R18 is worse than on 195/60/R17, if the same tires are used.. the tire width is what matters in snow!
There are winter tires that are very good to have if you live in an area with a lot of snow and ice. Winter tires provide more traction and are more flexible than all-season tires, so they give you more control on the road and are more durable in the cold.
If the snow tires have a bigger diameter than the others, the odo and the speedo will read a bit low. If the snow tires have a smaller diameter the odo and speedo will read a bit high.
No, snow tires aren't necessary for a vehicle with 4-wheel drive. You should look at the type of terrain your vehicle will be driven on most frequency. If you live in a place where there is more snow-fall than sunshine, snow tires might be a good fit. If you live somewhere with all 4 seasons, all-weather tires might be a better fit.
