If you live in an area that is exposed to harsh winter conditions then you will most likely already have winter tires waiting to be mounted on your car before the winter hits. If your area has a lot of icy roads that are difficult to manage with non-studded tires, you might want to go for a studded tire.
A studded tire will give you the best grip on icy surfaces. The extra grip can be very valuable and can manage to keep you out of accidents. The better quality tire that you buy, the better the chance is that you will be kept safe and out of trouble. The shorter braking distance can be the difference between a near miss and an accident. The money saved there will justify the premium quality of the tire.
