To make it short, selecting the right winter or snow tire is not difficult, as it all depends on what you need. If you need the best grip during winter due to very slippery surfaces, like ice and packed snow, then you should go with a studded winter tire.
If you experience more snow and slush and only occasional ice, then go with a non-studded tire. A non-studded tire will have sufficient grip on ice but is not as good as a studded tire. They are both approved for winter conditions, and they both perform well, so it is more of a preference because people select either one. The key is to go for winter and snow tiresthat are of high quality, and then you will be safe when driving during the winter.
The studded tires might not be available in your area, as they are not allowed in every state/province. Therefore, you need to be aware of the rules in your area and what applies to other areas that you might visit during the winter season.
In addition to the winter and snow tires, you also have winter approved all-weather tires that can be used during the winter season. They can actually be used all year round so that you don´t have to alternate between tires and store one set for half the year. These tires really add value when you live in an area with unpredictable weather.
