Snow Chains FAQ

Snow chains enhance traction by providing metal-on-ice contact, which digs into snow and grips icy surfaces. This increased friction helps prevent sliding and improves braking and acceleration in winter conditions. Chains are especially effective on steep slopes and uneven, snowy/icy terrain where tires alone may fail.

Snow chains are usually made from durable steel alloys that can endure extreme temperatures, friction, and pressure caused by driving on icy or snowy roads. High-grade carbon steel is commonly used for its strength and resistance to corrosion. Additionally, some chains feature anti-corrosion coatings or extra reinforcements to enhance their durability.

Yes, there are several snow chain types, including link-style, cable, and automatic chains. The most common and traditional type is the link-style chain, often wrapped around the tire treads in a "ladder" cross-chain pattern. Link-style chains can also be welded into different shapes and come in additional cross-chain tread patterns, such as "diamond" or "H" shapes, which affect the vehicle's traction. It's important to note that each state has its own criteria for approved traction devices, and non-traditional snow chains may not be permitted in some areas.

Snow chains are not inherently bad for tires when used properly. However, improper installation or driving on dry, bare pavement with snow chains can damage both the tires and the chains. Removing chains as soon as they are no longer needed is important to prevent unnecessary wear.

Yes, snow chains are highly effective on ice. They dig into the ice and provide traction where regular tires, even winter tires, might struggle.

Depending on your state, the speed limit when using snow chains is typically 25 to 30 mph. Exceeding this speed can damage the chains, tires, or road surfaces and increase the risk of accidents. Always follow state laws and the manufacturer's guidelines for your specific snow chains.

Yes, snow chains can be reused if they are properly maintained. After each use, clean them to remove road salt and debris, then dry them thoroughly to prevent rust. Store them in a dry location, preferably in their original case or a sturdy bag, to keep them organized and protected.

No, snow chains are not suitable for all vehicles. Some cars, particularly those with low-profile tires or limited wheel well clearance, may be incompatible with traditional chains. Cable chains, snow socks, or other state-approved devices may be better options in such cases. Always check your vehicle's owner's manual for guidance on snow chain compatibility.

Snow chains are legal in most states when hazardous weather conditions require their use. However, Florida prohibits snow chains entirely, and Hawaii restricts their use except when traveling near the summit of Mount Kea. Additionally, Oklahoma prohibits tire chains for vehicles with a rated capacity of over 2 tons.

• California, Colorado, Nevada, Oregon, Washington, and Wyoming require all vehicles to be prepared to chain up or have alternative traction equipment when driving through mountainous regions designated as a potential chain control area, which can include state and interstate highways.
• Additionally, Idaho, Montana, Tennessee, and Vermont require commercial trucks and busses to carry or equip chains on specific routes during winter conditions.
• Lastly, if a weather emergency is declared, several states may require chains or other traction devices on snow emergency routes, including Georgia, Maryland, New York, Pennsylvania, and South Dakota.

Yes, in many states, specific chain laws apply to commercial and heavy-duty vehicles, which differ from regulations for passenger vehicles. Typically, tractor trucks, trailer trucks, buses, and any vehicle towing a trailer must equip chains whenever road signs indicate they are necessary for passage. In contrast, passenger vehicles that are not towing may be exempt from this requirement, depending on local laws and weather conditions. In some states, it's mandatory for trucks to carry chains during the winter season when traveling through chain control zones in mountainous areas, just in case the weather necessitates their use.

In California, Colorado, Idaho, Montana, Nevada, Oregon, Tennessee, Vermont, Washington, and Wyoming, it's mandatory for heavy-duty vehicles like semi-trucks to carry or equip a minimum number of tire chains. This requirement applies when traveling on specific routes within each state during the winter season, which can range from September to May, depending on where you are traveling.

West Coast states and those in the Mountain Time Zone have far more intricate chain laws than the rest of the country. Washington has the lengthiest and most extravagant chain laws, covering both chain requirements and fine details like how chain manufacturers must forge the steel and how much a licensed chain installer can charge you.

If you are referring to strict mandatory requirements, the answer is likely Colorado. Among many other regulations, Colorado requires ALL motorists to carry chains or have approved traction devices from September through May when traveling on a nearly 126-mile stretch of I-70 west of Denver.

Yes, in addition to state chain laws, cities and counties may enact ordinances regulating or restricting the usage of tire chains on local roads. For example, many cities in the northeastern U.S. have designated snow emergency routes in case of severe weather. While chains may not be specifically required on these routes, you could receive a ticket if your vehicle obstructs traffic due to insufficient traction equipment, such as not having snow tires, four-wheel drive, or chains. Another good example is Missouri, which has no state-level chain laws, and all snow chain laws are regulated at the municipal level.

Depending on weather conditions, some states do not require snow chains for vehicles with snow tires or 4-wheel-drive (4WD). Emergency vehicles, including police cars and first responders, are typically the only vehicles universally exempt from local chain laws.

Snow emergency routes are designated roads prioritized for snow removal and maintenance during winter storms. These routes are critical for maintaining emergency vehicle access and safe travel conditions.

Vehicles parked on designated snow emergency routes during a declared snow emergency may be towed or fined to allow plows to clear the roads efficiently. In most jurisdictions, you can also receive a ticket if your vehicle is stalled or blocking traffic on a snow emergency route due to not having adequate traction equipment (such as snow chains, snow tires, or 4-wheel drive).

States with chain control zones on mountainous highways typically have a designated chain-up area before entering the "Chains Required" section of the roadways (usually within a couple of miles or near the last highway entrance/exit before the zone). Otherwise, you may need to pull over to the side of the road or a safe area to equip chains. Do not stop in the roadway to install chains. When you exit the chain control zone, you will often find a designated area for removing chains as well. Check our blog for more information on how to install snow chains.

When road signs indicate that chains are required, most states typically require you to chain at least two wheels on the vehicle's drive axle (one tire on each side). Towed trailers, especially those equipped with brakes, often require one or two tires to be chained on the rearmost axle. The total number of chains you will need varies for each state. You can find specific information for your state in our Snow Chains Law Guide.

For larger vehicles like semi-trucks, the total number of tires you will need to chain varies for each state and is often based on the vehicle's weight and/or total axle count. For example, an 18-wheeler in California will need at least six tires chained to comply with the state's law, and additional chains may be required if conditions warrant. You can find detailed state-by-state information for commercial vehicles in our Snow Chain Laws Guide.

Tire chains on passenger cars are typically only required for tires on one drive axle, which is the rear axle of most cars. If you are towing a trailer or another vehicle, your state may also require chains on the trailer's rear axle. If the state requires chains on all-wheel drive (AWD) and four-wheel drive (4WD) vehicles, only one drive axle will need chains. State authorities tend to close roads before conditions worsen to the point where more chains would be necessary.

If road signage indicates chains are required to proceed, most states require the towing vehicle, including passenger vehicles, to have chains or other approved traction equipment on the drive-axle tires. Trailers (or towed vehicles) typically require one to two chained tires on one rear axle, but exact policies vary from state to state.

Sometimes, but remember that approved traction devices and policies vary for every state. An alternative traction device approved for use in one state may not be approved in others. States that permit alternative traction devices (ATDs) may still require vehicles to carry tire chains in case weather conditions worsen, as the ATD may not provide sufficient traction to travel safely.

Snow chains and snow tires excel in different situations. Snow tires are a long-term solution for continuous driving on snow and ice, providing reliable traction and convenience. However, snow chains offer superior grip in extreme conditions like deep snow, black ice, or steep inclines, making them ideal for temporary use during severe weather. While snow tires are more practical for daily winter driving, snow chains are mandatory in some regions during extreme conditions, regardless of tire type.

Most states do not require all-wheel drive (AWD) or four-wheel drive (4WD) passenger vehicles to use snow chains, especially if the vehicle is also equipped with snow tires. However, in some states, these vehicles may still be required to "carry" chains in case road conditions worsen. If the weather is severe enough, you may see road signage similar to "Chains required for all vehicles, no exceptions," and local authorities or law enforcement may close down the road to all vehicles without chains.

"All-season" tires that have an M+S (mud and snow) rating and "all-weather" tires featuring a 3PMSF (three-peak mountain snowflake) symbol are considered "snow tires" according to state laws. States often categorize their chain laws into various tiers based on vehicle type and weather conditions.

• In milder winter weather, a state may only require vehicles to have snow tires, snow chains, or four-wheel drive in chain control areas.
• As conditions worsen, states commonly require chains on commercial vehicles, but they may still permit passenger vehicles equipped with only snow tires or four-wheel drive to proceed.
• During severe weather, the state's department of transportation or local authorities may require all vehicles to use chains, even if they are fitted with snow tires.

Snow socks are a lightweight and easy-to-install alternative to snow chains. They are made from textile materials that enhance traction by gripping the snow. While snow socks are quieter and suitable for low-clearance vehicles, they generally provide less grip than chains and may not meet legal requirements in some regions. They are best used for light snow and occasional use.

Studded tires can provide excellent traction on snow and ice, but they typically cannot be substituted for snow chains when chains are required by law. While studded tires work well for continuous driving on icy roads, snow chains provide better grip on steep inclines, deep snow, and severe winter conditions. Be sure to check your state's studded tire laws as well, as they are typically only permitted during specific months in each state.

You can buy Peerless snow chains for heavy-duty vehicles right here on our website. Otherwise, snow chains are widely available at automotive stores, online retailers, and tire shops.

Snow chains are sized based on your tire dimensions, which include tire width, aspect ratio, and wheel diameter (e.g., 225/60R16). You can find this information on the sidewall of your tires. Check the manufacturer's size chart to ensure compatibility and choose chains that fit snugly without contacting the wheel rims. Also, review your vehicle's owner's manual for guidance on the compatibility of snow chains, as they may not be suitable for vehicles with low clearance in the wheel wells.

Yes, snow chains can often be rented, especially in touristy areas with frequent winter weather or near mountain passes. Rental options may be available at ski resorts, automotive stores, or tire service shops. This is a cost-effective solution for drivers who only need chains occasionally.

Snow chains are best used for improving traction in snowy or icy conditions that could cause a vehicle to skid. Most states allow drivers to use snow chains at their discretion for this purpose. However, some states, especially those on the West Coast and in mountainous regions, may impose travel restrictions on certain routes due to winter weather and require vehicles to have tire chains to proceed. You can learn more about each state's exact regulations in our Snow Chain Laws Guide.
