The Ministry of Transportation recommended changing summer tires to winter tires at +5...+7 degrees. The department explained that one should focus on the average daily temperature and the appearance of stable frost. When it gets cold, summer tires lose their elasticity, which reduces road grip and increases braking distance. Moreover, from December 1 to February 28, the use of winter tires is mandatory. They can be checkered or unchecked, but should be marked accordingly. Photo: Gennady Cherkasov.
