Is It Necessary for Snow Chains to Precisely Match the Size?

In winter, snow chains are an essential tool to help you drive safely on icy and snow-covered roads. They provide extra traction and control, reducing the risk of accidents and ensuring safe passage. However, many drivers often wonder if snow chains must match the size of the vehicle's tires exactly, or if slight variations are allowed. In this article, we will explore the importance of choosing the correct size of snow chains, considering factors such as 9mm snow chains and various specifications involved.

To Understand 9mm Snow Chains

One of the key factors in choosing the correct size of snow chains is the thickness of the chains, usually measured in millimeters. 9mm snow chains are a popular choice for many drivers, for several reasons. These chains strike a balance between performance and ease of installation, making them suitable for various vehicles, especially those with limited tire clearance, such as front-wheel-drive and rear-wheel-drive cars.

The 9mm thickness of these chains offers a good balance between grip and clearance. The narrow profile of the 9mm chains allows them to fit closely on the tires without rubbing against wheel covers or other parts of the vehicle. This is particularly important for vehicles with limited tire clearance, as larger chains may not be suitable.

Additionally, SURECHAIN's 9mm snow chains usually come with various certifications such as TUV/GS, ONORM V5117, and EN16662-1, ensuring they meet stringent safety and performance standards. These certifications give drivers the confidence that the chains they are using are effective and reliable in harsh winter conditions.

Compatibility of 9mm Snow Chains with Different Types of Vehicles

Anti-skid chains are not a one-size-fits-all solution, and their compatibility with different types of vehicles may vary. Front-wheel-drive and rear-wheel-drive vehicles each have unique characteristics that may impact the choice of anti-skid chain size.

Front-wheel-drive vehicles rely on the front wheels for traction, making it crucial to install snow chains on these vehicles. As for 9mm snow chains, their slim profile and compatibility with front-wheel-drive vehicles make them an excellent choice. These chains can provide the necessary grip without causing clearance issues, ensuring your vehicle remains in control on icy roads.

On the other hand, rear-wheel-drive vehicles primarily use the rear wheels for driving, necessitating the installation of snow chains on the rear wheels for optimal performance. Similarly, 9mm snow chains are a versatile solution for these vehicles. Their design allows for proper installation on the rear wheels without damaging the vehicle or affecting its functionality.

Why Precise Size Is Important for Snow Chains

Although 9mm snow chains offer a flexible and effective solution for various vehicles, the importance of precise size cannot be overlooked. Choosing the correct size that fits your vehicle's tires is crucial to ensure the snow chains work effectively and safely. Here are a few reasons why precise size is important:

Optimal Traction

Choosing the correct size ensures that the snow chains fit snugly on the tires, providing maximum traction. Improperly tensioned chains may fail to grip the road surface effectively, reducing overall performance.


Precise sizing helps prevent the chains from rubbing against the vehicle's wheel wells or other components. Chains that are too large may damage the vehicle, while those that are too small may not provide sufficient traction.

Handling and Control

Snow chains of the correct size contribute to better handling and control of the vehicle. Chains that are too large or too small can impact your ability to maneuver and safely drive on icy and snowy surfaces.


Using the right-sized snow chains can extend their lifespan, ensuring they withstand the challenges of cold winter conditions. Chains subjected to constant stress due to improper sizing are more prone to rapid wear and tear.
