By putting winter or all-season tires on your Subaru vehicle, you'll ensure that you have traction in the cold weather and when driving on snow or ice. These tires have a unique, deep tread that gives you an improved grip on the road. Additionally, a special rubber compound is used to create these tires, which resists the cold temperatures better than regular summer tires.
It's best to swap out tires each season; however, you can avoid having to do so by investing in all-season tires. While all-season tires aren't made specifically for snow or any one time of year, they'll provide you with better traction and control than summer tires.
