The performance of your vehicle’s tires is directly related to the temperature outside. As the temperature drops, even the best summer tires will fail to respond road conditions. All-season tires, while designed for all types of weather, will not perform as well in ice and cold.
As a rule, whenever the average outdoor temperature falls below or climbs above 7 degrees Celsius (19.4 degrees F), your tires will be affected. As the temperature drops, non-winter tires loose elasticity and the grip they have on the road. That’s why the best tires to have when the temperature drops are winter tires. Conversely, winter tires will deteriorate faster in hotter temperatures.
