Summer tires are primarily designed for high-performance vehicles and provide optimal dry and wet performance levels in a temperate environment. Summer tires are not designed to be used during the winter season where temperatures are colder and approach freezing consistently as their performance would be less than optimal.
Winter tires are specifically designed to offer optimal levels of traction on ice, snow, and slush in addition to wet and dry road surfaces in severe cold weather conditions. Winter tires are not intended for year-round usage. All winter tires exhibit the Three Peak Mountain Snow Flake marking indicating suitability for winter application.
All-season tires are designed to provide balanced dry and wet performance levels, as well as acceptable snow traction in regions with light winter weather. A/S tires are a practical solution designed for year-round usage with typically a longer tread life.
