when rubber hardens in cold weather, so it makes it more difficult to stop quickly. It doesn't have to be below zero for your car to lose traction either. Winter tires can help at anything less than 7 degrees.

below 45 degreesF (7C) Fahrenheit. This is the point where all-season tire compounds begin to harden and lose traction. These tires must use denser compounds in order to deliver better wear. Micro pore or comparable technology is not suitable for these designs. For the same reason, no soft stud material is built into these tires (all season)
