Quick Summary

A snow tire is a type of automotive tire specifically designed to improve traction on snow and ice. These tires feature an extra-deep tread pattern that provides better grip compared to regular tires. While they offer significantly more pulling ability on loose snow and ice, they do not provide an advantage in stopping on glare ice. For icy surfaces, tire chains or studded tires are recommended. Studded tires typically contain about 100 studs made of tungsten carbide. Snow tires were first used around 1943.12
