A prerequisite for safe winter driving is that the car is equipped with the equipment best suited to the conditions. Snow chains are not a one-size-fits-all solution - there are significant differences in type, size, design and material quality between the models available on the market. It is important to choose the most suitable snow chain for your vehicle, taking into account the tyre size, the type of drive (front, rear or all-wheel drive), the narrowness of the wheel tracks and the regulations in your country.

It's not enough to have a "roughly good" chain - millimetres can make the difference between fitment and safety. The wrong size or type of snow chain can not only be ineffective, but can also damage the chassis, wheel tracks or even electronic systems. Premium snow chains are manufactured with advanced fastening mechanisms, self-tensioning systems and corrosion-resistant materials to ensure long-term reliability in extreme weather conditions.

The goal of this post is to help you not just choose one product, but make a decision that will enhance your vehicle and your own safety. We'll show you how to read the markings on the sidewall of the rubber, which certifications (e.g. TÜV, ÖNORM) to look for, and how to try on a snow chain in your home - before the first snowfall.

Finally, we also look at where and when snow chains are mandatory - for example in Austria, Switzerland or France - and what fines you can expect if you ignore the rules.

If you want to drive confidently in winter, the right snow chain is not just an optional extra: it's an essential safety tool. Stay tuned for our comprehensive guide to help you be prepared for the challenges of winter.

Why is a snow chain important?

The purpose of a snow chain is to reduce slipping on snowy, icy roads, ensuring vehicle stability and controllability. It is particularly important on mountain roads where the weather can change rapidly and slopes and bends can put increased stress on traction. The snow chain creates a mechanical link between the tyre and the road surface, significantly improving braking distance and lateral grip - especially when even winter tyres are not enough.

Its absence can pose a serious accident risk, as loss of control on snowy slopes or in corners can happen in seconds. In addition, many European countries, such as Austria, Italy and France, have strict rules on the use of snow chains. Failure to have a snow chain fitted and ready for use when properly marked (e.g. "B26" blue and white sign) can not only result in a fine, but can also lead to the insurance company refusing to pay compensation in the event of an accident.

It is therefore important to understand that a snow chain is not just a "practical winter accessory", but an indispensable safety device that can save lives - or at least prevent serious material and personal damage.

How to choose the right snow chain?

Choosing the right snow chain is key to safe winter driving. When making your choice, the type of car and tyre size should be a primary consideration, as there is a wide range of snow chain sizes to choose from.

The snow chain must fit the tyres exactly, otherwise it will not provide the correct grip and could easily damage the chassis, braking system or the tyre itself. You can always check your car's manual to see what type of snow chains can be used, as some models - especially low-rolling sports cars, hybrid or electric vehicles, and smaller SUVs - do not allow all chain types due to tight wheel arches or sensitive electronic systems.

It is important to consider how often and in what environment snow chains will be used:

• For occasional use (e.g. skiing or infrequent snowy trips) a simpler, hand-tensioned model may be appropriate.
• For regular mountain transport, however, a self-tensioning premium snow chain with a thicker material and a higher load capacity is highly recommended, even in extreme conditions.
• Fitting is also important: modern snow chains now offer tool-free, quick-fit solutions that are easy to fit in cold, dark or snowy conditions. Some premium models can be attached to a wheel in up to 30 seconds.

And don't forget the alternatives: textile snow chains (e.g. snow socks) are also available, which can be a good solution in certain situations (e.g. urban environments, low ground clearance cars), but typically provide less grip than metal chains and are not always accepted as official snow chains.

Finally, before buying, always make sure that the snow chain you choose has the appropriate certifications (e.g. TÜV, ÖNORM V5117/V5119, GS mark) to guarantee safe use and compliance with European standards.

Tyre size - the basis for a suitable snow chain

The first and most important step in choosing the right snow chain is to know exactly the size of your vehicle's tyres. This information can be found on the side of every tyre, for example 205/55 R16. These numbers are not random - they all contain important information:

205 - the width of the tyre in millimetres

55 - sidewall height as a percentage of width (tread height)

R - radial structure (nowadays available for almost all passenger cars)

16 - rim diameter in inches (inches)

Snow chain manufacturers tailor their products to these dimensions, so always search by exact size before buying. The packaging and the product description will always indicate which sizes the snow chain is compatible with. A single model can fit dozens of sizes - so it's important to consider the overall tyre size, not just the rim diameter.

Tip: If you don't know the size off the top of your head, look at the sidewall of the tyre on your car or check your vehicle's manual. Some cars also have a sticker with the factory dimensions on the inside door frame (e.g. the driver's side door opening).

Please note: When using winter tyres, you may have fitted different tyre sizes to summer tyres - the size of the tyre currently fitted is always the factor when choosing a snow chain.

Snow chain types: from the miracle snow chain to the automatic snow chain

There are many different types on the market, each adapted to different needs and situations - from traditional metal mesh chains to innovative automatic systems. In this overview, we present the most popular types of snow chains to help you find the best solution for your car and your driving habits.

Metal mesh snow chain:

The metal mesh snow chain is the "traditional" type of snow chain, it's what most people think of when they think of snow chains. They stand out for their long life and excellent grip, ensuring good driving performance even in the harshest winter conditions. Because they are made of steel, they are particularly robust and better able to withstand the heaviest snow and ice on roads.

However, because chains are stronger and heavier, they are more time-consuming and complicated to fit and require more space to store. For those who frequently travel in extreme winter conditions, metal mesh snow chains are the best choice if you are willing to take the time to install them.

Plastic snow chain, quick snow chain:

Plastic snow chains offer a lighter and simpler alternative to traditional snow chains, which is why they are also known as miracle snow chains. Plastic chains are quick to install and, because they are flexible, they are less likely to damage the car body or tyres. They are quiet, do not corrode and are easier to store because they take up less space.

However, the grip of plastic snow chains is not as strong as metal mesh models, so they are recommended primarily for lighter snow and ice conditions. If you are looking for a solution for short-term use in less extreme winter conditions, plastic snow chains can be a convenient and practical choice.

Textile snow chain (snow socks):

Textile snow chains, also known as snow skis, stand out for their simplicity and ease of use. These types of fabric snow chains are flexible, quiet and easy to put on, ideal for those who don't want to spend a lot of time fitting chains. However, textile snow chains are only suitable for short-term use as they wear out quickly on dry roads and do not offer the same grip as metal mesh versions. Nevertheless, if only occasional snow trips are required, snow chains can be a convenient choice.

Self-tensioning snow chains:

Self-tensioning snow chains offer an extremely practical solution for winter driving, as they are quick and easy to fit. Thanks to a special mechanism, there is no need to manually adjust the tension of the chains, making fitting quick and convenient. However, self-tensioning models are often more expensive due to their easy-to-use design and more advanced technology. If one is looking for maximum convenience and quick use, self-tensioning snow chains can be an excellent choice, but it is important to consider that their cost is higher than conventional chains.

Start-up snow chain:

A start assist snow chain is specifically designed for situations where your car's wheels get stuck in snow or ice and have difficulty getting started. This type is compact and quick to fit, making it an ideal solution if you suddenly need to increase traction, for example when getting out of a snowy car park or starting up an icy hill. The starter chain is usually only fitted to the driven wheels and is recommended for short-distance use.

Although it is not a replacement for a traditional snow chain, its simple design makes it a quick and practical aid when other means are not available. Such chains should be kept in the car as a spare, especially in winter.

Car snow chain: choice by car type

- Passenger cars: a wide range of snow chains is available for passenger cars. Depending on the tyre size of the car, it is easy to choose the right chains to ensure stability and safety on snowy and icy roads. It is important that the chain fits the tyres exactly, so that the car's handling is not reduced and accidents are avoided.

- SUVs, SUVs: SUVs and SUVs, due to their greater weight, require stronger and larger snow chains. SUVs and urban SUVs are often fitted with larger tyres and these types sometimes require special, stronger chains that can handle the extra weight of the vehicles. The right snow chain for suvs not only provides more traction on snowy, icy or muddy roads, but its material and design also requires increased durability and long life.

- Vans: for vans, which often carry heavier loads, extra heavy-duty and robust snow chains are recommended. For these types of vehicles, stronger metal mesh or even special extra heavy-duty snow chains are recommended to guarantee stability and safety, especially when the truck is driven on dense snow or icy roads.

What to look out for when buying?

Rules and regulations for snow chains

International rules

In several countries in Europe, such as Austria, Switzerland and Italy, the use of snow chains may be compulsory at certain times of the year or on signposted stretches of road. If you drive in these countries in winter, always carry a suitable snow chain.

National regulations

There is no general obligation to use snow chains in Hungary, but they are highly recommended in snowy or icy weather. On some stretches of road, for example in mountainous areas, you may not be allowed to drive without a snow chain.

When should the snow chain be on?

- On snowy or icy roads: snow chains should be used when tyres do not provide sufficient grip on snowy or icy roads. If the road surface is slippery, a snow chain will help to increase traction and ensure safe driving.

- On signposted road sections: if the sign "Snow chains are mandatory" appears, it is not only recommended but mandatory to use a chain. The signs indicate that the road section is so dangerous in winter that it is unsafe to drive without snow chains.

- Removal and fitting: snow chains should only be used on snow and ice, as they can damage the road surface and the vehicle on dry roads. If the road is relatively clear, the snow chain should be removed to avoid wear and unnecessary damage.

How to use a snow chain

Installing a snow chain is not a complicated task, but inexperienced drivers often have trouble with the process. Below are three important steps to help you use a snow chain correctly and comfortably, while maintaining safe and efficient driving. Keep these simple but key rules in mind to avoid problems with snow chain use in winter!

Location and preparation

• Stop on a safe, straight stretch of road.
• Turn on your hazard lights and wear a visibility vest.

Equipment steps

• Slip the snow chain over the wheel and attach the fasteners - if you are unsure, watch a video on how to attach a snow chain.
• Check that the chain is tight and stable.

In use

• After a few kilometres, stop and check the chain. If it is loose, adjust it.

Summary

Choosing and using the right snow chain is key to safe winter driving. Know the rules, choose the right type for your car and follow the correct fitting rules.
