Which tire feature improves traction in snow?

The feature that improves traction in snow is deep tread patterns. Tread patterns are critical in enhancing a tire’s ability to grip the surface it is traveling over, especially in adverse conditions like snow and ice. Deep treads allow for more surface area to contact the ground and help to channel snow and slush away from the tire’s contact patch. This design helps to prevent slippage, as the tire can better grip the road by biting into the snow or ice.

In contrast, options such as a slick surface do not provide the necessary grip, as they lack channels to displace water or snow. A wider tread width could improve stability but does not necessarily enhance traction as effectively as deep patterns do. Higher air pressure can lead to reduced tread contact area, which would negatively impact traction, especially in snow, where a larger surface area is desirable to engage with the snow effectively. Thus, deep tread patterns are specifically designed to enhance traction on snowy surfaces, making them the most suitable choice.
