What is the 7 7 rule for tires?
The 7 7 rule for tires provides a simple temperature guideline for timing your seasonal tire changes. Install winter tires when daily temperatures drop to 7°c (45°f) or below for seven consecutive days. Remove them in spring after seven straight days above 7°c. When do i change my tires? As we’ve already discussed, the temperature has a considerable effect on our tires’ effectiveness. More specifically, if the average temperature is 7 degrees c or higher, you should swap to all-season tires, and when it drops below 7 degrees c, it’s time for winter tires.
