Tire chains improve traction in snow and ice. There are three types: diamond, cable, and link. Some states require chains or snow tires in winter. Laws vary and chains should be in good condition. Emergency chains are available for temporary use.
Tire chains are devices intended to improve a vehicle’s traction in heavy snow and icy conditions. There are three general types of tire chains: diamond, cable, and link. A diamond-style chain gets its name from the distinctive diamond pattern of the interlocking metal strands. The cable version has a series of straight metal strips that run horizontally against the face of the tire. Link tire chains are a combination of cable and diamond styles, with a web of chain links running horizontally against the face of the tire. All three are effective for most winter driving emergencies.
The use of tire chains for additional traction is more common in mountainous areas and in regions that receive heavy snowfall. In fact, some states require the use of tire chains and/or snow tires while traveling on roads known to be especially dangerous in winter. This practice reduces the number of motorists stranded due to poor traction in isolated areas of the state.
Laws regarding the use of tire chains or other traction assist devices vary from state to state and occasionally from city to city. In general, tire chains should be in good working order and free of defects. Closing mechanisms must not be loose or broken. Driving with chains on bare pavement is not only dangerous, but it can actually be a misdemeanor in some municipalities. Chains can also damage road surfaces or be damaged by hard asphalt. The difficulty is that some drivers find the act of removing tire chains time consuming and unnecessary, especially if they are driving back to winter road conditions.
Some states also require (or at least allow) studded snow tires during certain times of the year. Using a combination of tire chains and studded snow tires may or may not be permissible, so it pays to be aware of your state’s regulations.
In an emergency situation, some tire chain manufacturers offer temporary use cable or link chain systems. These traction aids wrap around the tire and are secured with straps or hooks. Using these emergency chains can allow drivers to steer out of snow banks or icy patches on the road.
