Caution: due to the fact that different types of disks from different manufacturers can be installed on a car, the above data are averages; actual values for a particular car may differ by 15% in one direction or the other.
A car disk is, in fact, a wheel, its base, which bears the entire weight of the car. Disks are divided into two groups: steel and light alloys.
Steel wheels weigh more, but are much stronger than cast alloy wheels, while forged alloy wheels are stronger than steel wheels and lighter than cast wheels.
For example, for a BMW 7, a steel wheel weighs 9 kg, a cast aluminum wheel weighs 7.8 kg, and a forged aluminum wheel weighs 6.8 kg.
Discs come in different diameters: from 10 to 23 inches. For cars, wheels with a diameter of 13 to 16 inches are mainly used, from 10 to 13 - for ATVs and mopeds, above 16 - for tractors and special equipment.
Weight readings vary depending on the manufacturer and width, the table shows the average values:
| Disc diameter | Weight of one disc in kilograms |
| Steel disc (stamped) | |
| 12 inches (R12) | 4,5 |
| 13 inches (R13) | 5,2 |
| 14 inches (R14) | 6,3 |
| 15 inches (R15) | 7,4 |
| 16 inches (R16) | 8,5 |
| 17 inches (R17) | 12,1 |
| Cast light alloy | |
| 10 inches (R10) | 2,5 |
| 11 inches (R11) | 3,3 |
| 12 inches (R12) | 3,9 |
| 13 inches (R13) | 4,5 |
| 14 inches (R14) | 5,6 |
| 15 inches (R15) | 6,9 |
| 16 inches (R16) | 7,8 |
| 17 inches (R17) | 8,5 |
| 18 inches (R18) | 9,4 |
| 19 inches (R19) | 10,8 |
| Forged alloy | |
| 14 inches (R14) | 4,8 |
| 15 inches (R15) | 5,8 |
| 16 inches (R16) | 6,6 |

| 18 inches (R18) | 8,2 |
| 19 inches (R19) | 9,1 |
| 20 inches (R20) | 10,2 |
From time to time, manufacturers try to break the record for lightness of wheels, since the speed of the car depends on this.

Information varies everywhere. So I’m trying to clarify the exact data!
Thank you very much, and especially for your efficiency! And 695 on the KiKa website says 7.3 kg, and 451 6.520 kg. (shop.kolesa-kik.ru/catalo...ross-/37551.html?from=app) At the same time, 695 are written from the replica series and such a weight! Can you tell me what the weight of the factory wheels on the 2022 Grant-Cross is? I called the factory and they can’t tell you, these wheels are not available in the city, so I’m choosing, and you can’t tell me, maybe it’s better to put Slick with studded tires, otherwise She weighs about 10 kg, and where is the best place to buy it?
Wheel weight: every kilogram matters
Surely, you will not argue that the dependence of the car’s mass, acceleration and braking times are directly related. The heavier the car, the more difficult it is to accelerate it and the longer it will take to stop it, all other things being equal. However, the mass of a car is not a constant quantity. By removing from the trunk all the junk that has accumulated there over several years of owning a car, you can lighten it by 20-30, and often 100 kilograms. It's a lot.
However, not everyone keeps unnecessary things in the car, you might say. And you will be absolutely right. Therefore, let's move on to a more realistic development of the scenario. You can reduce the weight of your car by choosing the right wheels and tires. Moreover, this step will have very positive consequences, because the weight of the rims and tires is included in the total mass of the unsprung part of the car. Moreover, weight has a direct impact on such a parameter as inertia. Now it’s worth understanding the terms so as not to go further into a dead end.
Weight of alloy wheels R 12 -R 23
* 27 kg is the maximum weight of wheels with a diameter of 23 inches that was found in our catalogs. The variation in the weight of discs in this diameter is very different. The weight of discs R14, R15 and R16 from different manufacturers and models does not differ as much as that of discs with larger diameters, for example, R17, R18, R19, etc.

How do they look
Almost everyone can imagine what stamped wheels look like, since stampings are currently the most common car wheels - about 70 percent of cars use them. And also almost all commercial vehicles are equipped with stamps.
Many consider the appearance of stamped wheels to be their main disadvantage. Indeed, they do not have such a variety of designs as their forged and cast counterparts, and they are all similar to each other. Only the colors can differ radically.
Life time
The level of wear resistance of stamped discs is strongly influenced by two indicators:
- disc deformation while driving;
- corrosion.
Painted stampings
The second important factor that reduces the service life of stamps is that they rust. Accordingly, if the disk becomes very rusty, it will no longer be usable. Therefore, it is important to store car wheels in dry, indoor areas. Painting can also slightly prevent inevitable corrosion.
Basic drive functions
Wheel rims on a passenger car perform a number of important tasks:
- rubber seal around the perimeter;
- ensuring a rigid structure under the total weight of the vehicle;
- transmission of torque to the wheel.
Based on these functions, the car enthusiast can formulate requirements for the disks, as well as their technical characteristics. Any wheeled product must be balanced in size, durable and safe. Only after this can you proceed to drilling wheels on VAZ cars.
ATTENTION!
The exact parameters of such a product are difficult to determine, since each manufacturer uses its own types of raw materials in the manufacture of discs and its own design solutions.
A more significant difference between the estimated and actual parameters is observed for disks with a larger diameter. This is due to the fact that manufacturers use their own unique technologies and different stylistic options.
When determining the cost of transportation, transport companies prefer to base themselves not on the weight of the disks (table below), but on their dimensions (volumes). Such a calculation is more profitable for them. This applies to all types of wheels.
If you need to determine the volume and weight of your tires, go to the Tire Weight section. To calculate the external parameters of the wheel, use a calculator.

Disk size and other characteristics
Most often, alloy wheels for a Niva car are made of aluminum alloys, which gives the parts increased strength, corrosion resistance and an affordable price. Forged wheels made using titanium and magnesium are less popular, because despite their high strength, they are very expensive.
Steel products for Niva 2121 have also become less in demand in recent years, as they do not offer a variety of design solutions. The VAZ 2121 Niva usually comes with black or silver wheels. Less common are color options, which the car owners themselves specially order from workshops (individual painting).
In order to choose wheels for the Niva 21214 or other models of this car, it is worth remembering the basic rules of how these accessories are selected. First of all, you should always rely on the manufacturer’s recommendations. This is important, in particular, when selecting the width of the rim. The general provisions here are as follows - the width of the profile from the Niva 2121 tire itself should be approximately one third greater than the width of the rim.
The size of the wheels is also determined by the diameter of the rim, which coincides with the mounting diameter of the tire and is indicated in inches. To select, you need to look at the value of the mounting diameter after the letter R (means radial tire) and, accordingly, select the article numbers for it. The most common modification is r15, less often - r16, r17.
The weight of these car accessories when traveling is as important as the size of the rims. It is known that some samples can reach a weight of 20-30 kg, so this parameter must be taken into account, since weighted wheels put a greater load on the engine and contribute to an increase in unsprung weight.
Disk structure
VSMPO wheels It must be said that products that can be installed on the Niva, r16 or r15, are offered by many domestic and foreign manufacturers. To this day, motorists have good memories of VSMPO Niva products, the production of which was officially discontinued several years ago. OJSC VSMPO-AVISMA Corporation stopped producing wheels due to its concentration on the production of elements for aircraft construction, developments for engines and withdrawal from the automotive market. Today, only in certain stores you can find remnants of VSMPO samples on Niva or buy used copies. More often there are covers, rings, caps, that is, accessories for disks that are ordered via the Internet.
VSMPO disks belonged to the forged class. They were manufactured using hot die forging technology, which gave aluminum alloys the best properties. The fact is that during forging, the metal becomes layered (instead of granular, as in casting), which leads to increased strength combined with lower weight. This gives less unsprung weight, and, as a result, leads to improved dynamics during braking and acceleration, reduced fuel consumption, and improved handling, which is perfectly felt by the driver.
Technologies that were used to produce components from the VSMPO Niva company now work in aircraft landing gear. Forged metal has a higher threshold for plastic deformation and is susceptible to rupture only under extremely high emergency loads. Strong thin rims allow for good “spring” under load, which made it possible for previously produced Niva articles to successfully participate in reducing the impact of the road on suspension elements and wheels.
What type of disk to choose
If you drive long distances every day on country roads with high-quality surfaces, pay attention to alloy or forged wheels. Less weight with sufficient engine power and good torque will save on fuel. Due to the noticeable difference in price, when choosing between cast or forged, it is based on financial capabilities.
If you travel daily on roads with poor-quality surfaces or off-road, then the choice is iron wheels: they are repairable and inexpensive. And when you drive exclusively in the city and rarely go on the highway, you don’t have to take the weight into account: you won’t be able to compensate for the difference in cost in fuel consumption. In this case, you choose between stamped, cast and forged wheels according to taste and wallet.
Analogues of VSMPO disks on Niva
Tuning Niva wheels
If you need forged wheels, it will be quite difficult to find them on Niva. For example, today such products for sizes r16 are offered under the Sarmat brand. These are alloy products for SUVs, with five double thick spokes, with dimensions 6.5 x 16, center hole diameter 98.5 (mounting rings may be needed during installation), fastening with 5 screws with a distance between them of 13.94 cm. Reach 3.8 cm. Products are produced by KRAMZ and cost about 3.7-4 thousand rubles per disc.
The same KRAMZ produces a forged model “Barkhan” with a rim width of 5.5 inches for the Niva r16. The mount for model 21214 is the same as that of the Sarmat. The disc is different:
- less impressive appearance (six thick “rays”),
- overhang of 5 cm,
- weighing 6.7 kg.
The 21214 car can also be fitted with Magnum wheels on the r16, which are distinguished by a darker metal color and beveled, forked three “rays”. One disc weighs 7.75 kg, has a central hole of 98.5, an offset of 5 cm, five mounting holes located at a distance of 13.94 cm. Unlike the Barkhan, the Magnum series is produced without a cover.
Based on the above, it can be argued that VSMPO drives have received worthy successors in the Russian market, including in the niche for the 2121 series.
Sprung and unsprung mass
In order to understand how wheel weight can affect a car's handling, dynamic performance, ride quality and suspension durability, it is necessary to understand what forces act on the car while driving. One of the main parameters that guide engineers when developing a suspension for a particular car model is the ratio of the sprung and unsprung mass of the car. What it is?
A spring (spring, shock absorber strut) is an elastic suspension element that softens the shocks that occur when a car moves over uneven road surfaces. Thanks to this element, impacts are transmitted to the body only to a small extent, which determines the smoothness of the ride and comfort of movement. The sprung mass is the mass of parts of the vehicle that are separated from the road surface by a spring (body), and the unsprung mass is the mass of parts that are located between the road surface and the spring (wheels, tires, hubs, brake system elements).
Stamping of car wheels with a diameter of 14 inches
Stamped car wheels are so called because they are made using the stamping method:
- A plate, the central part, is extruded from a steel blank using a stamping press. The stiffeners are pressed through. Holes for the bolts are drilled. The unnecessary edge is removed. The plate is ready.
- Next, the rim is made. A long sheet of steel is cut. Bends into a cylinder. Welded along the seam, the seam is cut off for smoothness. The cylinder is pressed with a press, the shape of the disk is set. The edges are sanded.
- It would be more correct to call such a disk stamped-welded. Since only the central part itself is stamped, and the rim is obtained by rolling, then the two parts are welded.
- At the end, a hole for the nipple is drilled. Covered with paint.
Among the disadvantages are susceptibility to corrosion, high weight, worse balancing, which means worse road stability and controllability.
Weight table
For clarity, we summarize the weighing results in a table. The star indicates an atypical result: as a rule, stamped wheels weigh more than cast ones.
| R15 | R16* | R17 | |
| Stamps. | 8.28 kg | 8.80 kg | 12.88 kg |
| Cast | 7.04 kg | 9.46 kg | 10.78 kg |
| Forged | — | — | 9.70 kg |
How to choose original rims
Popular Russian manufacturer of stampings TZSK. Often on the market you can find products from Chinese Trebl, which are not durable. The largest manufacturer of dies is the Ukrainian plant KrKZ. More expensive options for stamped car wheels are also available. For example, these are KFZ stampings, which are more expensive, but of better quality. Wheels of this brand are presented in basic configurations of the Volkswagen and Toyota concerns.
A large number of car models, especially in the basic configuration, are supplied by the factory with stamped wheels. And that motorist who wants to acquire original wheels must look for products recommended by the manufacturer of his car.
