Why Should Tires Be Changed in Winter?
Tires should be changed in winter to improve grip, handling, and overall safety on icy and snowy roads. Winter tires are specifically designed to perform better in cold temperatures, offering enhanced traction compared to all-season or summer tires.
According to the Tire and Rubber Association, winter tires are engineered with rubber compounds that remain flexible in low temperatures. This helps them maintain better contact with the road surface and enhances vehicle control.
The underlying reasons for changing tires in winter include temperature drops and changing road conditions. In temperatures under 7°C (44°F), standard tires can harden. This reduces their grip and increases stopping distances. Winter tires, in contrast, use a softer rubber that stays pliable. The tread patterns on winter tires are also designed to channel snow and slush, reducing hydroplaning risks.
Technical terms such as “tread pattern” refer to the design of the grooves and channels in a tire. These improve traction by allowing the tire to grip the road better. “Hydroplaning” occurs when a tire rides on a layer of water instead of the road, which can cause loss of control. Winter tires mitigate this effect thanks to deeper treads.
The mechanisms that make winter tires more effective involve various features. The specific rubber compounds in winter tires stop being rigid in cold weather. The tread depth and pattern provide enough space to disperse snow and water. This improves contact with the road surface, facilitating better braking and acceleration.
