Snow chain tyres

Types of snow chain tyres

Snow chain tyres, also called snow chains, are used on vehicles to provide better traction when driving through snow and ice. They are fitted onto the outside of a vehicle's tyres. Snow chains come in various types, such as:

• Link chains: These are the most traditional and widely used types of snow chains. This snow chain tyre consists of metal links that are interconnected to form a chain. The links are usually made of hardened steel to resist wear and corrosion. Link chains provide good traction on icy roads, but they can be noisy on dry pavement.
• Cable chains: Cable chains are similar to link chains, but instead of metal links, they have thick steel cables. The cables are arranged in a pattern that resembles a chain. Cable chains are lighter and less expensive than link chains. They also offer decent traction on snowy roads. However, they may not perform as well on sheer ice compared to link chains.
• Spiral chains: Spiral chains feature a unique design with spirals or coils along the chain. This design helps to grip the snow better and reduces the risk of slippage. Spiral chains are effective in deep snow conditions. Nevertheless, their performance might be affected in icy situations where more biting edges are required.
• Diamond pattern chains: This type of chain features a diamond-shaped arrangement of the links or cables. This pattern provides more contact with the road surface and distributes the pressure evenly across the tyre. As a result, diamond pattern chains offer superior traction and durability. They are suitable for both snow and ice conditions. Nonetheless, they tend to be pricier than other chain types due to the complex construction.
• Self-tensioning chains: Self-tensioning chains are equipped with automatic tensioning systems. This eliminates the need for manual adjustment after installation. The self-tensioning feature ensures a snug fit on the tyre, optimising performance and safety. These chains combine the benefits of other designs while adding the convenience of self-tensioning technology. As such, they are perfect for various road conditions, especially in extreme winter environments.

When choosing snow chains, it is crucial to consider the expected road conditions, the type of vehicle, and the chain's compatibility with the tyre size.

Specification and maintenance of snow chain tyres

Specification of snow chain tyres is important for both safety and performance reasons. Snow chains are designed to fit specific tire sizes and have varying link patterns and materials that affect their performance.

• Tire size

  The chains must be the same size as the tire to ensure a proper fit. The tire size can be found on the sidewall and is listed in width aspect ratio-diameter format. Example: 205/55 R16. The first number is the width of the tire in mm. The second number is the aspect ratio, which is the height of the tire sidewall in mm. The third number is the diameter of the wheel in inches. For example, 205/55-R16 means the tire is 205 mm wide, with a 55% aspect ratio and 16-inch diameter. Snow chains are required in some areas. They improve traction on ice and deep snow. Installing chains properly is important for safety and to avoid damage to vehicles and roads. When installing chains, check the manual for instructions specific to the vehicle. Incorrect installation can cause problems while driving.

• Link pattern

  Chains with diamond or square links provide better traction. The chain material affects the performance and durability of the chains. Steel chains last longer than other materials. However, they are heavier and can damage tires if not used correctly.

Inspecting snow chain tyres before and after use is important to ensure safety and performance. Look for broken chains, worn links, and rust. Worn links can reduce traction. Rust can weaken the chains over time. Proper cleaning after use in salt or slush areas is important. Rinse with water to remove salt and debris. Allow chains to dry completely to prevent rust. Proper storage keeps chains in good condition for the next use. Store in a dry, cool place away from sunlight. Protect chains and tires by removing chains when no longer needed in winter. Continued use on dry pavement can damage tires and chains. Regularly checking the owner's manual for the vehicle's chain installation and use instructions is important. This ensures safety and proper use, as different vehicles may have specific requirements for chain installation and use.

How to choose snow chain tyres

Wholesale buyers can get snow chains for sale, but before they place their orders, they need to consider the following factors:

• Vehicle type and usage

  Buyers should consider the type of vehicles the chains will be used on and the roads and terrains they often drive on. For instance, a heavy-duty truck operating in rural areas needs more durable chains than a passenger car used in urban settings.

• Size selection

  It's essential to get chains that are the right size for the tires. Incorrectly sized chains can cause damage or inadequate performance. Buyers can find the tire size on the sidewall of the tires or the vehicle's manual.

• Type of snow chain tires

  There are different types of snow chains, and each is suited for a specific purpose. For example, the ladder-type chains offer good general performance and are affordable. However, the V-bar chains are more expensive and offer excellent traction in icy conditions. Buyers should choose a type that fits their budget and needs.

• Material construction

  Snow chain tires are mainly constructed using steel. The chains made from carbon steel are more durable and resist corrosion, making them suitable for harsh winter conditions. Those made from nickel-plated steel are more affordable and suitable for occasional winter use.

• Ease of installation

  Buyers should consider how easy the chains are to install and remove. Some models require special tools, while others have manual installations or even self-tightening options. First, wholesalers should evaluate the installation time and decide whether the installation requires a professional or can be done at home.

• Legal requirements

  In some regions, especially areas with heavy snowfall, there might be legal requirements for using chains under specific conditions. Wholesalers should familiarize themselves with such regulations and ensure the chains meet the necessary standards.

How to DIY and Replace Snow Chain Tyres

Here is a step-by-step guide on how to install snow chains for tires:

• Choose a safe location

  The first step is choosing a safe location away from traffic. This allows drivers to install chains without distractions or hazards.

• Lay out the chains

  Once the location has been selected, the snow chain tires are laid out on the ground. This allows drivers to inspect them for any twists or tangles.

• Drive into position

  The vehicle is then moved so that the tires with the chains are on the side with less traffic. This ensures the driver can install the chains without worrying about passing vehicles.

• Position the chain

  The chain is positioned over the tire. The rubber tensioners are then placed over the top and bottom of the tire. This helps keep the chain in place during driving.

• Secure the chains

  Once the chains have been positioned, the tensioners are pulled tight. This ensures the chain fits snugly against the tire. The links on both sides of the tire are also secured. This prevents the chain from slipping off while driving.

• Check the fit

  After the chains are secured, the driver checks the fit. This is done by driving a short distance and then stopping to inspect the chains. If necessary, the tensioners are adjusted to ensure a proper fit.
