If you decide to use winter tyres, when should you replace the summer tyres with winter ones?
Safe driving
Explanation
To decide when to change summer tires for winter ones, it is important to consider the **ambient temperature**. Winter tires are designed to offer better grip and performance when the temperature falls below **7 degrees Celsius**. This is because the rubber of summer tires hardens at low temperatures, reducing their ability to adhere to the road.
- **Winter tires**: They are made with a rubber compound that remains flexible at low temperatures, improving traction in cold conditions, even if there is no snow or ice on the road.
- **Temperature as an indicator**: Changing tires based on temperature is more effective than waiting for the first snowfalls or a specific date, as the weather can vary significantly from year to year.
Therefore, the best practice is to switch to winter tires when the ambient temperature drops to **7 degrees Celsius or less**, thus ensuring safer driving in cold conditions.
