Tire pressure parameters for various Kamaz models

Correct pressure in truck tires is one of the important parameters of wheeled vehicles, as it affects many characteristics. In this article we will figure out what the correct pressure should be in truck tires. The following mainly depends on pressure:

• comfort of driving in a car, which is important for long trips;
• optimal mileage and fuel consumption;
• transmission of forces when accelerating the car.

In addition to the factors described above, incorrect pressure is one of the causes of accidents on the road. When the permissible norm is lowered, the car frame is strongly compressed, resulting in unfavorable factors:

• significant reduction in tire life due to uneven wear;
• truck tire overheating;
• rolling resistance increases significantly.

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

These are just some of the negative consequences of improperly inflated truck tires. For example, lowering the norm by only 30% leads to a significant increase in fuel consumption, equal to one tenth of standard waste. In addition to the negative factors, tire wear is doubled. The braking distance also becomes longer by 15%.

Exceeding standards, like underestimating them, also leads to negative results.

The main problem that truck owners face when driving with overinflated tires is their uneven wear and, as a result, significantly increased wear.

Reduced tire life increases the cost of vehicle maintenance and can lead to accidents. Properly inflated tires allow you to avoid all the problems described above, and also optimize fuel consumption and halve the cost of changing tires.

Tire pressure parameters for various Kamaz models

Driving safety on public roads excludes the possibility of driving on wheels with tire pressures that differ from the standard. Kamaz is a heavy vehicle, which, despite all its advantages, has a large mass, and it is difficult to keep it on the road with flat or overinflated tires. The material aspect is also important due to the high cost of components and spare parts.

KamAZ-43118

It is probably difficult today to find a person who does not know the cars produced by KAMAZ OJSC. This is not surprising, since the enterprise is the largest in the world among factories producing trucks. Today, however, product output is far from production capabilities, but the plant is working to improve the quality of its models. The testing department of our editorial team managed to obtain for testing a rather interesting car from the wide range of the car plant’s model range - KamAZ-43118 with a 6x6 wheel arrangement.

The machine is equipped with a turbocharged engine and intercooled charge air. The engine develops power of 245 hp. at 2,000 rpm and maximum torque 1,060 Nm at 1,200–1,400 rpm. The car has a flatbed body, starting immediately behind the cabin, of the maximum possible length. Accordingly, the spare wheel is not located in its usual place, but at the rear under the frame. The KamAZ-43118 body can be with or without an awning. You understand that not everyone needs an awning, and the opportunity not to pay for an unnecessary accessory when buying a car pleases the consumer.

It is very pleasant to note that the carrying capacity of a three-axle all-wheel drive vehicle is 11 tons. And our car is equipped with a tire pressure regulation system, and it is equal in the tires of all axles. Thanks to this, the inconveniences that we encountered when experiencing some all-wheel drive two-axle vehicles disappear (see “Two-axle vehicle from Miass”).

What's new in this KamAZ? In short, firstly, tires size 425/85R21 with a speed index J, corresponding to a permissible speed of 100 km/h. And in terms of load capacity, they are quite sufficient for this machine. And secondly, it is equipped with a ZF 9S 109-494 gearbox, 8-speed, with a top gear ratio of 0.74. Why we drew your attention to this will become clear later. Thirdly, the cabin of our car is equipped with a hydraulic lift. In this case, it is a necessity: it is simply impossible to raise the cabin at such a height manually. Probably everything is new.

Properly inflated tires save money

Any vehicle driving on flat tires causes unnecessary financial expenses, and Kamaz especially. Low pressure will bring a lot of problems, regardless of the model and application:

1. Kamaz 4308. A city truck with a small wheelbase and carrying capacity. Number of stingrays - 6.
2. Kamaz 4310. The so-called “timber truck”. Suitable for traveling over rough terrain, off-road, and dirt roads.
3. Kamaz 43118. A universal vehicle that is used as dump trucks, tractors, and flatbed trucks.
4. Kamaz 5320. In most cases, it is an on-board vehicle adapted for movement on asphalt.
5. Kamaz 65115. A draft horse designed for work in the industrial sector (construction, mining, metallurgy, etc.)

Truck tires

Naturally, the pressure in the wheels of KamAZ 65115 is higher than that of KamAZ 4308. In any case, if you do not maintain it within normal limits, the consequences will be:

• decreased controllability;
• premature wear and failure of chassis and gearbox parts;
• increase in braking distance;
• risk of disassembling the wheel while driving;
• excessive fuel consumption.

Overpressure in Kamaz tires will also not bring anything good:

1. The central part of the tread will quickly wear off.
2. Increased pressure in the tires of a Kamaz vehicle is the cause of skids and accidents.
3. Vibration destroys the body, frame and all mechanical components and fastenings.
4. The risk of puncture increases.
5. The tire may explode.

It doesn’t matter what the pressure is, but if it doesn’t meet the standard, the risk of harming road users and your wallet increases significantly.

How does inflation of KamAZ 43118 wheels work?

wear, loss of tightness of air supply seal units: connecting hoses and fittings; malfunction of air shut-off valves; wear of the sealing collar; failure of system controls, reduced and nominal pressure regulators.

How to inflate the tire of a Kamaz all-terrain vehicle?

1. Close the wheel valves on all wheels of the vehicle.
2. Set the distributor switch to the left position.
3. Pull out the handle of the reduced pressure regulator and by rotating the handle set the reduced pressure of compressed air in the air supply line to the tires.

What pressure should be in KamAZ 43118 tires?

As we have already said, the car is equipped with a centralized tire inflation system. The tire pressure gauge has an upper limit of 6 kg/cm2, and the recommended tire pressure is 5.6 kg/cm2.

How does the tire inflation system work?

The system automatically inflates and deflates the tires depending on driving speed. The CTIS receives its operating air from the same compressor as the brake system, a pressure switch ensures that no air enters the CTIS until the brake system is full.

How does the tire inflation work on gas 66?

Tire pressure regulation system for GAZ-66

1) consists of compressor 1. ... When the pressure in the system increases to 5-5.5 kg/cm 2, the pressure regulator connects the unloading cylinder with the air cylinder, as a result of which air under pressure enters the unloading cylinder and moves the piston 6 (see.

What type of brake mechanism is installed on the drive axles of the Kamaz 4310?

The service brake system is made on drum brake mechanisms, drum diameter 400 mm, lining width 140 mm, cam release.

How to check the pressure in KAMAZ tires?

The pressure in KAMAZ tires must be checked regularly. ...Rules for checking tire pressure

1. you need to find the air valve on the wheel and unscrew the plastic cap;
2. installing a pressure gauge on the valve (you need to lightly press on it to make a hissing sound);
3. The exact value will appear on the pressure gauge after installation.

What pressure should be in Ural 4320 tires?

Tire pressure and driving speed should be adjusted to suit the road surface. When driving on a good highway with asphalt concrete pavement with a rated load, the tire pressure should be for the Ural-4320-31 car - 320 kPa (3.2 kgf/cm2), KamAZ-43114 - 300 kPa (3.0 kgf/cm2).

How does wheel inflation work on Zila?

When the handle is installed in the right position (“Pumping”), the spool moves to the left (Fig. 454, b), the recess of the spool, located opposite the left oil seal, connects the left cavity of the housing with the middle one, and compressed air enters the tires, the tires are inflated.

How does the tire inflation system work in the Urals?

From the cavity of the assembly, air flows through the axle shaft channel to the air shut-off valve and then through the connecting hose into the wheel tire. The tire pressure regulation system includes a pressure control valve with a limiting valve that limits the pressure drop in the pneumatic system (see.

What pressure is considered nomative?

The quantity and degree of compression of air pumped into the cylinder must be as indicated in the specialized table attached and the instruction manual. On a metal plate attached to the cabin doorway. If the data is unreadable or the plate is missing, make sure that you always have a printed memo in your glove compartment, which indicates what pressure should be in the tires of your Kamaz.

The table shows the relationship between tire size and standard pressure. It also depends on the axle load. Different models have different pressures. Thus, the lightweight KamAZ 43118 rides on wheels with less inflation than the heavy truck KamAZ 65115. But in some cases it is even recommended to artificially lower the tire pressure.

Truck tire pressure

Publication date: 08/12/2020

Truck tire pressure is an important parameter that has a significant impact on the performance characteristics of the vehicle. It mainly affects ride comfort, tire service life, fuel efficiency, braking distance and vehicle stability.

Factors affecting tire pressure

This indicator is significantly influenced by the time of year. When the temperature rises to +20 °C, it increases by 0.7 bar, and when it drops to -20 °C, it drops by 0.6-0.8 bar. When vehicles are heavily loaded and during long trips, the changes in indicators will be greater.

During constant use, it is recommended to monitor the tire pressure of a truck using sensors 2 times a week. This must be done in cold tires (the tire temperature is equal to the ambient temperature), since during active use the tire warms up, which leads to an increase in performance. When pumping cold tires, follow the manufacturer's recommendations.

Review of the best summer and winter tires

Size and price are proportionally dependent quantities. The larger the wheel diameter, tread width and depth, the more expensive the purchase will be. Optimal wheel options suitable for use in winter:

The manufacturer Ling Long offers comfortable, reliable tires. The only “disadvantage” of such a product is its relatively high cost. The minimum price of the T820 model is from 24 thousand rubles. A reasonable option is tires from the same manufacturer, but of a different model - 18PR LM329. One wheel costs approximately 17 thousand rubles.

A good solution would be a set of tires made by Cordiant. It is less durable than the analogues discussed above. However, it will please the buyer with a relatively low price - only 14 thousand rubles for 1 cylinder. Another domestic manufacturer, KAMA, offers good options.

Summer tires for a KAMAZ vehicle are somewhat cheaper - they differ in their composition and tread type. For 2022, an excellent solution would be to purchase the following tire models:

Summer Long March tires are slightly cheaper than winter tires - from the same manufacturer. Slightly lower class wheels from the BOTO company. They are relatively inexpensive. However, the braking distance and controllability when using them are at a decent level. If you have the funds, a good choice would be a model from the manufacturer ADVANCE - the company produces premium all-terrain tires. The cost of products from this manufacturer will be from 45 thousand rubles per wheel.

Democratic solution - I-P184 ns10. The price for one wheel will be approximately 18 thousand rubles. This model will be a compromise solution.

Consequences of pressure deviation from normal

Incorrectly adjusted pressure in truck tires leads to unpleasant and sometimes very dangerous consequences.

A decrease in this characteristic below the norm causes:

• Reducing the service life of tires by almost half due to their uneven wear and overheating.
• Significant increase in braking distance. For unloaded vehicles it is extended by 15%, for fully loaded vehicles – by 20%.
• Cord fatigue, leading to the inability to restore the tread pattern.

What pressure should be in truck tires?

Pressure indicators for trucks are divided into three types:

• Maximum. The maximum permissible pressure is specified by the truck tire manufacturer. It is usually applied to the side of the tire. Constantly inflating a tire to this level reduces its wear resistance and increases the likelihood of dangerous situations on the road.
• Optimal. This value is determined from a table that indicates the recommended pressure for a specific amount of cargo being transported. Owners of trucks usually focus on the optimal value: maintaining it ensures a long service life of the tires and economical fuel consumption. It is difficult to adhere to the optimal value, since it requires frequent monitoring and inflation of the tire.
• Recommended. This value is usually indicated by the manufacturer for each wheel. Recommended pressure for truck tires is calculated for maximum load conditions. When transporting cargo whose weight is significantly lower than the maximum permissible values, tires are inflated to a level below the recommended level. Load and speed indices (maximum values ​​of these parameters) are indicated in the tire markings.

Often, the operating instructions indicate two pressure values ​​for truck tires - one for an unloaded vehicle, the second for a vehicle with a maximum load. If one value is indicated, then it is intended for an empty car. For heavy loads or long-distance trips without luggage, it is recommended to inflate the tires by 0.3-0.5 bar.

To independently select the pressure level in a truck tire, you should:

• Take a table with optimal values ​​for a certain vehicle load.
• Select a value taking into account the axis on which the wheel is located.
• Read the manufacturer's individual recommendations.

What non-standard sizes can be installed?

Although there are some restrictions associated with the installation of wheels on a given vehicle, some types of non-standard tires can be installed without any detrimental effects. Controllability will not deteriorate and structural elements will not be damaged. On KAMAZ 65115 vehicles it is allowed to install tires with the following overall dimensions:

• 00R20 (280R508);
• 245/70 R19.5;
• 425/85R21;
• 1220×400-533.

In addition to those listed above, there are many other alternative options. However, it is worth familiarizing yourself with the technical characteristics of the wheel you are purchasing in advance.

The ideal option is to try the purchased tire on your vehicle before paying. This will eliminate the possibility of problems in the future. But not all stores will allow you to install a new wheel.

If for some reason you cannot purchase wheels recommended by the manufacturer, you should contact specialists in this field. This will avoid various problems associated with the breakdown of wheel arches and mudguards. You should pay attention not only to the diameter and height of the tire. But also on the type of profile. It significantly affects the following:

• vehicle cross-country ability;
• maximum possible speed;
• braking distance length.

Width also has a significant impact on driving performance. For example, by increasing this parameter you can:

• reduce the braking distance;
• make the control system more responsive;
• make cornering easier.

However, using tires with a wider width than standard increases gas mileage. Usually 1.2 – 1.5 times. This parameter ranges from 3-8%.
