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. It is not recommended to use winter tires in summer or hot weather conditions. They are made with rubber compounds that keep the tires flexible and provide traction, even in temperatures below 45°f (or 7°c).When the seasonal temperature falls below 7 °C (46 °F), it’s time to switch to winter tires. Winter tires perform well in all cold weather conditions, ranging from snow and ice to wet and cold dry roads. When seasonal temperatures climb above 7 °C (46 °F), fit your wheels with summer tires.Short answer: You shouldn’t use snow tires year round (unless you live in a year-long winter region). Winter tires are designed with an aggressive tread and deep tread depths that bite into snow, slush and ice. Accelerating, braking, and maintaining traction is its key function.
What is the 7 7 rule for winter tires?
If you leave them on too late, your winter tires will degrade quickly. So, when is the right time to swap? The rule of thumb is 7-for-7: wait until there are seven consistent days at 7 degrees Celsius. The reverse is also true for transitioning to winter. Nonetheless, the recommended time to switch over to Winter Tires should be late September to early November.
