Novice Guide To Measuring Tire Chains

January 18, 2023January 18, 2023 | Tire Forge

Tire chains are a necessity in cold and hilly regions where even the best of snow tires fail to grip the snow-covered roads. Not only in snowy regions but many areas with challenging slippery terrain also require tire chains. 

The tire chains help grip the road by clawing onto the ice, mud, or snow-covered tarmac, and by doing so, the vehicle gains forward momentum. 

Without a tire chain, the vehicle would spin its wheels without moving forward.

In some snowy regions of the north, it is mandatory by law to have snow chains in the vehicle in case the weather turns extreme.

A tire chain isn’t just a simple chain that goes around the tires. It consists of a side chain, a cross-chain, and tire links for the entire setup to work properly. 

The Sidechain or, the link chain helps connect the links and the cross-chain. It forms the framework of the entire tire chain.  

The cross-chain goes around the tire and looks very different from a typical chain. That is because the cross chain’s job is to provide traction so the vehicle can move forward. The cross-chain comes in contact with the tire and road. 

Links are the blocks that make up the cross-chain. These individual pieces connect to make a cross-chain.

A link is designed to grip the road and the tire to enable traction on icy/ snowy roads. Links can be studded links, V-Bar links, or net links based on the size of the vehicle and nature of use. 

Using the correct size tire chains is the key to making them work properly. However, one must first check if tire chains can be used on their vehicle.

If there are restrictions on tire chain usage, it could be indicative of a reduced space between the tires and the vehicle body. In such instances, the usage of tire chains is not recommended.  

Tire Sizes

Take a look at your old tires to determine the correct size. The image shown in this example indicates your tire’s specs as well as what they mean.

• P —  Tire type
• 245 —  Tire width in millimeters
• 75 —  Sidewall height to width aspect ratio
• R —  Tire construction
• 17 —  Wheel diameter in inches

Tire width can be known by checking the sidewall of the tire. Manufacturers offer all the information about tire sizes and the specification. For the measurements, one could find a fraction number on the tire wall in large font. 

For example, if the size of a tire is 185/70- 15. The numerator factor of the fraction in this case, which is 185 is the width of the tire in millimeters. 

The aspect ratio is the ratio of the overall ratio of the height of the sidewall compared to the width. The higher the number, the thicker the sidewall of a tire is and vice versa.

This information can be found in the same fraction number as mentioned earlier.

For example, if the size of a tire is 185/70- 15. The denominator factor of the fraction in this case, which is 70, is the aspect ratio of the tire in millimeters. 

The wheel diameter can be termed as the length of an imaginary straight line that passes through the wheel from one end to the other.

This information too can be found on the sidewall of a tire. It is crucial to know the diameter when buying snow chains. 

For example, if the size of a tire is 185/70- 15. Number 15 in this case is the diameter of the wheel in inches. 

One needs the tire width, aspect ratio, and wheel diameter information to choose snow chains of the correct size. 

Sometimes, the type of vehicle can also influence the tire chain’s compatibility. If the car is a medium-sized sedan, it may need chain links of a particular kind to tackle ice, mud, or snow.

On the other hand though, if the vehicle in question is a large heavy pickup truck that finds itself often on hilly unpaved terrain in winters.

Then a different type of snow chain with suitable links would be compatible as compared to the tire chains for a medium-sized sedan. 

While it is important to choose the right size tire chain, one should also ensure the kind of activity the tire chain is used for.

Tire chains come for many applications and a variety of vehicles, hence one must choose the right tire chain. 

To go a little deeper, tire chains can differ from vehicle to vehicle despite the size remaining the same. An off-roader would need a different type of tire chain when compared to a small hatchback that performs city duties. 

On the other hand, the purpose of the task and terrain the tire chains are going to be used for also make a huge difference.

There are specific tire chains for deep snow driving, for driving on icy roads, chains for mud use, chains for light snow driving, etc.  

We suggest one determines the tire size of their vehicle, the application for vehicle use, and the kind of terrain the vehicle would be used on. These details would help in choosing the right tire chains.

Yes, we suggest the tire chains be of the same size as the tires so that they fit perfectly.

A loose tire chain may easily come off and be ineffective. On the other hand, a tight tire chain could easily break or snap off under stress. 

Tire chains of the exact size prove to be more reliable over time. Since they are used in extreme conditions, incorrect sized tire chains could lead to one being stranded in extreme conditions, sometimes even in remote areas. 

Lay the chains entirely next to the wheels that receive engine power/ drive. Ensure that the parking brake is engaged.

The Tines on the chain must face upwards. You may then drape the chains on the wheels with caution and precision until 3/4th of the tire is covered.

Tuck the ends of the chain under the tire.

Drive forward by about two feet to bring the tucked part of the chain on top. Ensure the links are in place. Connect and join both ends of the chain using the anchor system. 

Inspect to ensure that the chain is evenly installed and is tightened from all sides. Even alignment along the sidewall and a snug fit is key to installing the chains properly. Make necessary adjustments after inspection.

Drive for about 100- 150 feet and then stop again to inspect the chains. This should give you an idea of how tight the chains are. If found loose, they need to be tightened.

Once the corrections are done, the vehicle can be driven with the chains under specified speed limits.  

Ideally, the wheels that get the drive from the engine need to be chained since they would require the most amount of traction. If the vehicle is an all-wheel-drive vehicle, all four wheels can be chained.

While choosing the right chain in terms of size and function isn’t rocket science, one needs to be careful in making the correct purchase decision to be worry-free in difficult situations, and for that, it is important to have the correct size tire chains.

How to choose a chain. Complete guide. Types, features and examples of use of

A chain is a flexible long product made up of links connected in series and movably. This ingenious invention of mankind in modern realities has not lost its former popularity and is widely used on ships, in ports, in logging, in cargo transportation, in production, in the mining industry, agriculture, everyday life, interiors and landscape design.

Chains are distinguished by purpose, design, material, link size, strength and many other features that determine the scope of their application. Among the huge variety of link structures, four main groups can be distinguished.

General Purpose Chains

This group includes steel round link chains of normal strength with a caliber from 2 to 16 mm with welded links. They are manufactured in accordance with DIN 763, DIN 5685 Form C (long link) and DIN 766, DIN 5685 Form A (short link) from grade 2 mild steel. and non-lifting loads. In the household, they are used to tie animals, raise well water, make swings. Chain branches, consisting of long links, have better mobility, but are inferior to analogues with a short link in strength.

Comparison between short link and long link general purpose chain

Load and haul chains of normal strength

These are products with quality class 2, 2.5, 3.5, 5, 7, 8, with a stress at a minimum breaking load of 240 to 800 N/mm². They go to the manufacture of chain slings and are used as part of various lifting and transport machines and mechanisms. With their help, overall and heavy loads are attached to water and land transport. They are mainly used with blocks and winches, for tying, suspension, lifting and holding loads; traction - for moving goods. Manufactured in accordance with GOST 2319or TU (manufacturer's internal standards).

Heavy Duty Load Chains

This group includes high-strength hardened chains of class T(8) with a tensile strength at breaking load of 800 N/mm² and above. They are made from a round steel bar with a section diameter of 4 to 20 mm from high-alloy steel. The place of closure of the rings is welded by electric welding and processed from the burr. Finished products undergo high temperature quenching to improve load capacity, fatigue strength, resistance to abrasive materials and excessive friction. Calibration of each link guarantees high accuracy of shapes and sizes and allows them to be used for work on sprockets of load-lifting and traction devices. Technical requirements for them establish standards GOST 30188-97 and GOST 25996 (for mining equipment).

Decorative chains

This group of products impresses with a variety of shapes, sizes, colors and materials used, which implies many options for their application. Thanks to various coatings, they perfectly imitate non-ferrous and precious metals, which allows you to realize any creative idea in interior design and landscape design. Decorative chains are often used by designers of costume jewelry, clothes and haberdashery. Plastic chains with links of bright signal colors are used for zoning public spaces, parking lots, sports grounds.

What is the chain pitch and gauge

Step is the measurement of the internal length of each individual link. Manufacturers may use the letter "P" or t to indicate the pitch, for example P = 24 mm or t = 24.

Caliber is the nominal diameter (d) of the section of the round steel from which the links are made. Often, gauge refers to the size of the chain, such as 8 mm, 10 mm, 12 mm, etc. More often, however, the size designation includes caliber and pitch separated by a multiplication sign. For example: 6x19mm, 8x24 mm, 14x50 mm.

Classification of welded round link chains

Depending on the pitch to gauge ratio, the chains are divided into:

• short link (type A)
• long link (type B)

When choosing a chain for certain applications, consumers often ask themselves: - "What is the difference between a short link and a long link chain, other than the obvious size of the links?"

The short link design (P/d < 3.5) makes the chain easier to handle, less prone to tangling when stored in a storage container, but not as agile as a long link chain. Its main advantage is in terms of strength: with the same caliber, a chain with a short link can withstand greater loads than with a long link. It is more difficult to damage when tightening at sharp corners. Short links are tighter on the gripping hooks, so there is less risk of them slipping off.

The long link construction (P/d ≥ 3.5) has a large degree of freedom in all directions and is better suited for fastening, extension, shortening. It is easy to make a loop out of it by threading a link into a link. But its main advantage over the short link is in less weight and price, since there are fewer rings per meter.

Conclusion: The type of chain must be selected depending on the tasks assigned to it. If mobility and weight are less important criteria than strength, then you should opt for a short link. In hoisting mechanisms with blocks and drums, only short-link chains are used for operation in order to prevent the occurrence of a large bending moment.

Important: When purchasing, make sure that the internal dimensions of the link are sufficient to pass a hook or other connecting elements (shackles, rings, carabiners, eyelets, etc.) through it.

Round link chains are divided into:

• calibrated (version 1)
• uncalibrated (version 2)

What is the difference between calibrated chains and uncalibrated chains?

The calibrated chain is made of round calibrated steel and has a high accuracy of execution within the specified strict tolerance for pitch, section diameter, link width, external and internal length. The maximum deviation from the regulated dimensions is ± 3%. Calibrated chains after heat treatment are necessarily subjected to tension by a calibration load in order to obtain the specified maximum deviations of the pitch and length of the segment.

Uncalibrated chains have a rated tolerance of ±10%, therefore they are designed to work on smooth drums or in static fastening systems.

Where are calibrated chains used?

A calibrated chain is used as a flexible lifting and traction body for chain conveyors, elevators, winches, hoists and other mechanisms with gear drums or chain sprockets. It works as part of bucket conveyors, lifting equipment, traction and lifting mechanisms with manual and mechanical drives. Sprockets or drums are usually designed and manufactured to ensure compatibility with a given chain size and gauge for optimum engagement.

Note: Both types of chains can be used as load chains.

How to choose a chain that will not stick or slip on sprockets?

It's not enough to get the gauge and pitch right, it's important that the chain is calibrated to tight tolerances or it will "bounce" under load. When the link pitch has deviations from tolerances of more than 3%, this is difficult to determine visually, but is easily confirmed in practical tests. A slippage or sticking problem usually occurs after the chain has gone through a few turns under load.

How to check chain calibration?

If you are looking for a calibrated winch chain and are unsure of the quality of the sizing, there is an easy way to check that it matches the tolerance limits for your winch drum.

To do this, you need to buy a meter length of the chain branch and measure the length of 11 links. Why exactly 11 links? – because it is a generally accepted standard length. Use a ruler to measure the distance from the inside of the first link to the inside of the last link. When doing this, make sure the chain is taut to ensure an accurate measurement.

Important! The maximum pitch deviation for a calibrated chain must not exceed ±3% of the specified value!

Table 1. Normal measurement results for a calibrated short link chain DIN 766

Caliber, mm	Pitch, mm	Length 11 links, mm
6	18. 5	203.5
7	22	242
8	24	264
10	28	308
12	36	396
13	36	396

Tip: For European-made anchor winches, choose calibrated DIN 766 short link chains as they will fit perfectly on the drums mounted on them.

Strength rating of round link chains

In the characteristics of the product, manufacturers indicate three types of load. The maximum working loads are based on proof tests and should never exceed the rated working loads suggested by the chain manufacturer, individual specifications or testing agency for the chain size and grade in question.

Working load (carrying capacity) - the maximum load that the product can be subjected to during operation. It is the breaking load divided by the safety factor. This coefficient varies from 3 to 8 depending on the purpose of the chain and the manufacturer. Usually it is 4, in which case the working load is a quarter of the breaking load.

The proof load is the reference tensile test load that was loaded on the specimen at the factory during the test procedure. Typically, it is twice the ultimate working load, which is half the breaking load. This is a very important test, proving that each link has been welded well.

Breaking load is the ultimate tensile strength of 4 times the working load limit. Standards require a specific level of breaking load for each chain size, gauge and grade. For some manufacturers, it may exceed the minimum standard, which is reflected in the test certificate.

Circuit calculation example:

When choosing a welded round link chain for the lifting mechanism, a simple calculation is performed for a given load and safety factor.

For example: For a manual hoist, the size of the calibrated chain must be selected. Assumed maximum working load: S = 12 kN (1200 kgf).

In accordance with the standards of Gostekhnadzor, we accept a margin of safety equal to 4.5: 1.

We calculate the breaking load according to the formula P = 4.5 x 12 kN = 54 kN (5400 kgf) .

According to table 2 (source: GOST 2319-81), we select a short-link calibrated chain of size 13x36 mm, for which the tensile strength is 66 kN (6600 kgf).

Table 2. Dimensions and loads for load and haul chains, type A, version 1

Caliber, d mm		Pitch, p mm		Width b mm		Previous deviation section length l=11p	Load, kN

42		118	-	142	-	-	340.0	680.0

What is chain quality grade?

Quality class is a characteristic that allows you to evaluate the strength of the chain. It depends on the mechanical characteristics of the finished product, and not on the ultimate strength of the alloy used for its manufacture. The quality class is usually indicated by numbers from 2 to 12. Some standards, for example, GOST 29996-97, establish the letter designation of the class - B, C, D.

Chains of normal strength (cargo, traction and general purpose), depending on the mechanical properties, have the appropriate quality class - 2; 2.5; 3; 3.5; 5; 7, and high-strength (lifting) class 8, 10, 12 (T8, T10, T12).

Table 3. Strength values ​​for chains of various quality grades

Quality class	2	2. 5	3.5	5	B	7	8(C)	10(D)
Test load stress, N/mm	75-120	120	240	315	500	600	640	800
Tension under breaking load, N/mm	150-240	240	360	500	630	750	800	1000

With the same nominal diameter of the links, the load capacity of the chain of the 8th quality class is 50% higher than the load capacity of the chains of the 5th quality class, and the load capacity of class 10 chains is 25% higher than that of products of quality class 8. Accordingly, the load capacity of class 12 is 25% higher than class 10.

The use of high-strength chains in lifting and rigging operations allows you to reduce the weight of chain slings. With equal load capacity, the weight of the chain of the 8th quality class is 30% of the weight of the 3rd class. The higher the quality class, the higher the surface hardness of the bows and the higher the wear resistance and susceptibility to damage from sharp edges.

Effect of Temperature on the Load Capacity of High Strength Chains

Their carrying capacity remains stable when operating in the temperature range from -40 to +200ºС. With an increase in temperature to +300ºС, the workload drops by 10%, and when it rises to +400ºС, it decreases by 25%. If the threshold of +400ºС is exceeded, operation is prohibited.

What chains are used on car tires?

To ensure the stability of the car when driving on ice, loose soils and snowy winter roads, snow chains are used. These are ready-made chain products that are put on the wheels of cars and make it easy to overcome even the most impassable areas. For their manufacture, high-strength hardened galvanized steel is used, which guarantees special resistance to abrasion, reliability and durability.

The range of snow chains covers almost all possible wheel sizes. The special pattern of the ladder, diamond or honeycomb chain tread provides optimal grip and comfortable movement.

How to choose wheel chains?

On finished chain protectors, manufacturers indicate the size of the tires and the type of vehicle for which they are intended. For those who plan to make wheel chains with their own hands, we recommend using the following gauge and link pitch:

• for cars: 3.5x12 mm
• crossovers, SUVs, commercial vehicles: 4.5x16 mm
• trucks, buses and special vehicles: 7x24 mm

Chain consumption depends on the wheel diameter, tread width and profile height of the tire, as well as on the selected pattern. For example, to “shod” two wheels of a passenger car in lugs with a “ladder” pattern, approximately 15 meters will be required.

How to choose an anti-theft chain for a bicycle or motorcycle?

One of the most reliable ways to protect an unattended motorcycle or bicycle from theft is a bike chain lock. It's easy to do it yourself. To do this, you will need a piece of chain and a padlock (with a key or combination). You should not look for an old chain in the garage or purchase it at a hardware store. For an anti-theft chain-lock, you need not an economic, but a high-strength solid hardened chain.

The anti-theft chain is made of thermally hardened steel and has an increased strength class T-8. It is difficult to cut it and it is almost impossible to bite even with a powerful bolt cutter. And not every thief carries hydraulic scissors or a grinder in his pocket. The chain links are firmly welded, so they cannot be unbent with wrenches. Even experienced hijackers will have to tinker with such a chain, and this will give you time or the attacker will look for another, less secure candidate for hijacking.

What is the optimal length and gauge of an anti-theft chain?

Leaving a two-wheeled "horse" in a temporary parking lot, it must be fastened to something immovable and indestructible (pole, tree, fence), and the chain must wrap around not only the wheel, but also the frame. Otherwise, a surprise will await you in the form of a lone chained wheel. Depending on what you will fasten your bike or motorcycle to, the length of the chain can vary from 60 to 120 cm. As for the diameter of the chain bar, it can be 8 mm, 10 mm or 13 mm. As practice shows, the larger the caliber of the link, the less chance the hijacker has.

If the chain is not in doubt about the reliability, then the weak link in this anti-theft device may be the lock. Time is important for a thief, so he is unlikely to start poking around in the castle when you can just bite his shackle. Therefore, the locking shackle of the lock must be no less strong than the chain links.

The assortment of the Krepkom store always has hardened chains of any caliber and chain locks with a high degree of protection against opening, breaking, sawing and corrosion. Instead of a bow-shaped bracket, the locks have a thick locking pin made of extra strong hardened steel. It is difficult to get close to it with wire cutters, a mount or a hacksaw, which makes it difficult to break in by force.

The Krepkom store offers a wide range of chains for various purposes and finished products from them (household, sanitary, decorative chains, knot, ball, anti-skid chains, for tying livestock and slipway repair, etc.). If you have any questions when choosing, our specialists are ready to advise you by phone: +8 (800) 333-21-68.

How to choose snow chains for wheels

In winter, drivers often have to drive through icy, snowy and other difficult terrain. Without additional equipment to prevent slipping, it is extremely difficult to overcome such sections of the road. Once faced with such difficulties, many motorists begin to investigate the question of how to choose chains for wheels.

Purpose of using anti-skid accessories

The presence of winter and even studded tires is not a guarantee that the machine will pass through ice or deep snow. But a car equipped with snow chains is more maneuverable, able to overcome deep snow, mud or sand.

And if in our country car owners somehow manage with studded tires, then in Europe a wheel chain is a necessary element of car equipment, along with a first aid kit and a fire extinguisher. For driving without this equipment on some roads under certain weather conditions, the driver will face a substantial fine.

Snow chains will also be appreciated by outdoor enthusiasts (hunters, fishermen, skiers), summer residents and anyone who cares about the safety of passengers and seeks to improve driving comfort in difficult conditions.

Types of snow chains

There are several types of such equipment. To choose the right model, you should understand the differences between them:

1. Chains . They have high traction qualities, are distinguished by endurance and long service life. The disadvantage of this type of design is the complexity of operation. Breaking them can damage the wheel and body.
2. Belts . They are easier to use, easier to store and maintain, but they do not have the same traction characteristics and fail faster. But a broken belt is safe for the car.
3. Bracelets are a stronger and more durable analogue of belts, but inferior to them in ease of use.
4. Tracks - anti slip tape. This studded rubber mat helps get a stalled car out of a pit. An excellent assistant to the driver moving in off-road conditions.

Choose the type of equipment based on personal preferences and the tasks that it must solve.

Set usually consists of 2 pieces, matching 10-15 interchangeable sizes. As a rule, if we are talking about infrequent use and not very difficult driving conditions, the equipment is mounted only on the drive axle. An all-wheel drive car is easier to drive if all 4 wheels are “shod”.

Differences between bracelets and chains

Bracelets are another additional protective accessory that improves vehicle flotation. The design is a belt with a buckle for mounting and an anti-slip base.

The driver puts on the bracelets by passing them through the wheel disk. The set includes from 2 to 12 pieces. The more they are worn, the smoother the movement will be. Although they are easier to put on than chains, it will take more time to install several bracelets on one wheel than chains.

It is not advisable to install bracelets on a steel disc - over time it will gradually cut them.

So, if the wheel is already loaded or the driver wants to get more traction, bracelets will do. Smoother running and better handling are easier to achieve with chains with diamond weave.

Product class and materials of manufacture

Different models of anti-skid equipment differ from each other in a number of characteristics, in particular, the material of manufacture, weaving and link size. The scope of application of structures depends on these parameters. For example, for ice it is recommended to choose a model with small links. The large link is designed to move through mud or deep snow.

It is customary to distinguish two classes of equipment:

1. Soft . The so-called "wheel mesh" is made of plastic, rubber, polyurethane. Its advantage is that it does not greatly increase the diameter of the wheel. Plastic or rubber lugs make it easier to overcome areas covered with loose snow, but provide little to no traction on ice. Since the rubber loses elasticity in cold weather, it is difficult to put on the mesh. The maximum permissible speed is not more than 80 km/h.
2. Rigid . The material of manufacture is hardened steel or titanium. Resistant to abrasion and impact, but wear out the tire tread faster when driving on a hard surface. Designed to move through mountainous terrain and "deep" off-road. The main condition for use is speed up to 40 km / h. This is due to the inertial increase in the radius of the chain during movement and the risk of damaging the wheel arch.

The life of each product depends on the material and the conditions and intensity of use. For example, soft wheel nets usually wear out within one to two seasons. To extend the life of accessories, you should follow the manufacturer's recommendations for their use.

Types of weaves

Grip of the wheels with the ground is achieved by means of chain mesh with different types of weaves. The most common drawings are "rhombus" (or "honeycomb") and "ladder".

The first option works well in the case of side skids, increases the car's off-road capability without overloading the transmission and suspension. Full repetition of the shape of the wheel guarantees smooth rotation. Suitable for trucks and other large vehicles.

Ladder pattern is convenient in terms of mounting method and provides good traction potential. It is used for rectilinear movement, with side drifts it is less effective. However, jerks during wheel rotation damage the transmission, suspension and steering components. It is because of the jerks that chains with such weaving are usually mounted on non-steered wheels.

Specialists pay attention to the following pattern: the more complex the weaving, the better the machine's cross-country ability.

Chain link width

Chain selection also depends on the link width. On some car models, only fine-mesh chains protruding above the tire surface in the range of 15 mm can be installed. It is desirable to mount 9-12 mm on passenger cars, trucks - from 16 mm.

Narrow links perfectly follow the shape of the wheel, although wear faster on a heavy vehicle. Wide ones provide increased cross-country ability of the car, but they wear out the tire treads of a small wheel more strongly.

Basic model selection criteria

Before buying chains, there are some disadvantages of this type of equipment to consider. If you use it constantly, you should be prepared for increased noise, as well as stress on the suspension, steering, transmission. Also, many of the minuses include a speed limit.

The following should be taken into account even before purchase:

• intended operating conditions;
• type of vehicle: passenger car, SUV or SUV;
• winter tire size and profile width and height;
• suitable mounting method: standard, automatic tightening, technology without the use of additional mechanisms.

Please note that this equipment is designed exclusively for difficult road sections and not for continuous driving.

Helpful Hints

Before fitting the chains, it is advisable to remove the caps and check the tire pressure.
