雪胎的不同在于:纹路+抗低温。
Snow tires (also known as winter tires) have tread patterns specifically designed to dig down and bite into snow and ice, plus they are made from softer rubber compounds that retain their flexibility in cold weather, allowing the tire to better conform to the surface of the road. (Regular tires tend to get hard and brittle in cold temperatures.) As a result, winter tires keep a better grip on snowy and icy surfaces than regular all-season or summer tires. Grip is critical -- not just to avoid getting stuck, but to ensure that the car can stop and steer. Life-saving safety technologies such as antilock brakes, electronic stability control and all-wheel-drive cannot do their jobs if the tires can't maintain their grip on the road surface.
