What happens if you use all-season tires in winter?
winter tires are made with a special rubber compound that stays flexible in temperatures below 45º f. this means those tires can grip the snow and road better. In contrast, all-season tires can become rigid in colder temperatures, reducing grip on the road. 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.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.So, when is the right time to swap?
