In autumn, every motorist takes care to change the tires of their cars in time for winter. For drivers , it is best to replace tires when the temperature on the street does not rise above +7°C . In addition, it is better to replace tires after a run of 50 thousand km. Run of 50-100 thousand km is considered the minimum. Drivers change their winter tires in such a way that they will be able to pass the test at +7 or +10 degrees. In fact, there is a very simple rule that all drivers must follow: You need to switch to winter tires when the temperature on the street does not rise above +7 . This regulation is clear and applies to both buses and minibuses. The run of the test consists of stopping at every traffic light at or near +7 or +10 degrees. Winter tires must be installed at or near the street to pass the test. A more detailed instruction, which is necessary for all drivers, can be found here. But what I want to note is worth saying once again: It is better to change the tires early in the season than in mid-season or late . Long, hot weather begins to affect the safety of both the driver and passenger during the winter season. Therefore, it is better to switch to winter tires when the street temperature does not rise above +7 or +10 degrees .
