Winter tires are designed to grip in colder, winter conditions, not just in snow. These tires provide extreme grip in weather below 45 degrees Fahrenheit. Winter tread patterns are also designed to provide excellent grip in icy and snowy conditions. Winter tires are engineered specifically to perform most effectively in harsh environments where colder temperatures are the norm. They don’t just combat snow and ice, they’re specifically designed and tested to function better in areas where temperatures can drop down well below freezing.
