If the temperature is below 7 degrees Celsius, winter tires have an advantage. The effect of winter tires is much greater than that of four-wheel drive. If the winter effect of four-wheel drive is 10 points, the effect of winter tires is 70 points, and the other 20 points are ground clearance.
All-season tires or summer tires are made of hard rubber, which has good wear resistance and high temperature performance. The winter tires use relatively soft rubber, which can still maintain grip at low temperatures. The lack of grip means that the braking distance is lengthened. In the case of a rear-end collision in summer, a rear-end collision may occur in winter. The vehicle will also be in danger of slipping due to insufficient grip when turning.
The best situation is of course to change summer tires in summer, and winter tires when the average temperature is below 7 degrees. Of course, if you live in a city where the temperature is below 7 degrees Celsius for only a dozen days a year, and there is almost no snow, you can also use the four-season tires for a few days. Be careful when driving and keep a safe distance. If you live in an area with cold winters and frequent snow, winter tires are a must. For the safety of you and others, please remember to change.
