Question 4802
If you decide to use winter tires, when must you switch from summer tires to winter tires?
- When the ambient temperature drops below approximately 7 degrees Celsius.
- As soon as the first snow falls.
- At the latest, in early December.
Show answer and explanation
Correct answer: When the ambient temperature drops below approximately 7 degrees Celsius.
If you decide to use winter tires, fit them when the temperature drops below about 7 °C. In that cold, summer tires already have less grip, whether there is snow or not. There is no fixed date, and waiting for the first snowfall is too late.
