Tire pressure UAZ farmer 390945 according to the passport

Modifications
• Tire pressure cannot be determined by eye; always use a tire pressure gauge.

• Heating of tires from sunlight can significantly affect tire pressure, remember this when taking measurements on each side of the car.

• You should not overinflate tires to save fuel; the savings will be very insignificant considering the future costs of repairing the chassis and replacing worn out tires.

• When using all-season tires, the pressure decreases with the cold weather; do not forget to inflate the tires when the season changes.

• When using pumping at a gas station, check the final pressure with your pressure gauge; gas pumps are usually inaccurate due to poor condition.

• The pressure range indicated on the sidewall of the tire is the maximum permissible for the tire when it is cold.

• If you still decide to keep the pressure at maximum, never exceed the values indicated on the tires themselves.

Car tire pressure: table of running models

Hello, dear friends, as well as new readers of our site! It’s very nice that there are more and more of you. Special thanks to those who tell their friends about us. We really appreciate it.

Today we will talk about the tire pressure of a car, the table of which will be presented below. Based on it, you can understand the main indicators and choose the right pressure for the wheels of your car.

Updated UAZ-390945 Farmer: forever young

At the beginning of this year, the cabover family of Ulyanovsk trucks, now in their seventh decade, was again modernized. We are fascinated by the retro while driving the updated “tadpole”.

We are used to the fact that the UAZ Patriot is regularly improved: the technical components are improved, the design is improved. All these innovations are heard and visible. And around the Ulyanovsk “old guys” - cabovers (more than 60 years on the market!) the information background is not so dense. Many people are not aware that these cars have also changed significantly in recent years: they have acquired power steering, front disc brakes, and a five-speed manual transmission. Passenger “loaves” are required to be equipped with ABS.

And at the beginning of this year, the cabover family was again modernized. To evaluate the updated UAZ-390945, I went to Ulyanovsk.

Evolution of a classic

While I was flying on the plane, I studied the changes made. The list, frankly speaking, is small.

“This is really not a radical modernization,” UAZ chief engineer Evgeniy Galkin anticipated my question. “Our cabovers are the most affordable all-wheel drive commercial vehicles on the market, and they are valued for that. Here are the sales data last year: everyone dipped except us! If the model is radically updated, the price will increase significantly - and we will lose our main competitive advantage.

Therefore, we decided to improve the car point by point. The main complaint from buyers was the weak frame: cracks in it were not uncommon, especially in the places where the power steering and body supports were attached. We introduced additional reinforcement in these areas, increased the thickness of the cross member, and the complaints should come to naught.

In addition, the frame and body are now separated not by an ephemeral gasket, but by a soft cushion that effectively absorbs vibrations - the easiest way to identify the 2016 “tadpole” is by it.

The interior of the pre-restyling “loaf” was distinguished by extreme asceticism.

Important units

Let's start with the fact that each car has its own rules and regulations regarding what operating pressure the tires should have. The norm is 2-2.4 atm, but everything is relative and varies depending on the parameters.

Therefore, if you have a VAZ, Mercedes, Toyota, Gazelle, Ford, Volkswagen or some type of truck, you need to look for a special sticker.

There is no universal formula even for a bicycle, car or some kind of motorcycle, for example. Therefore, UAZ Bukhanka, UAZ Patriot, Renault Duster and any other vehicle, including all-terrain vehicles, rely on the manufacturer’s recommendations. Factory stickers must be on all cars. But sometimes it wears out, wears out, or falls off. In such a situation, check the instruction manual for your model. Recommended pressures are indicated in this literature.

Now let's move on to what units of measurement are used. In Russia, for example, like many other countries, the unit of measurement is BAR (atmosphere). 1 atm equals 1 kgf/cm2. But if you go into details, then in 1 atmosphere there are 1.013 bar. In practice, it is not so important how much error there is between them. These units are equated to each other.

But in the USA they use the PSI unit. It shows the number of pounds per square inch. If the car is from the USA or the car contains recommendations for pressure in PSI, there will be no problems with conversion to conventional units.

To do this, just divide PSI by 14.5. That's all, the translation system is extremely simple.

How is pressure measured? The most common device is a pressure gauge. Every motorist has it, it is inexpensive, but it shows the pressure with a slight error.

To obtain the recommended operating pressure when the pressure gauge shows a lack of air inside the tires, drivers use:

pumping is a pump that pumps air by working with arms or legs;
compressor - connects to a power outlet or is powered from the on-board network;
equipment at the service station.

Useful tips

Based on the make, model and installed wheels, it is not difficult to figure out what the normal tire pressure is. It is not enough just to have something that measures pressure. It is important to understand why this control is needed and what you need to know about swapping in general.

Pressure checks and adjustments are carried out when the tires have not yet warmed up. That is, before the trip, and not during. This will allow you to obtain the most accurate parameters without error. If the tires warm up, the pressure on the pressure gauge will increase. In winter it decreases. In general, the error is usually from 0.2 to 0.4 Atm.
In winter and summer, the wheels should be inflated and lowered. If you overinflate tires in winter, they will become more oaky, causing you to start jumping on the roads and losing contact area between the tires and the road surface. In summer, on the contrary, it is better to inflate the tires so that the rubber does not float and retains its performance characteristics longer. Car manufacturers must indicate the recommended pressure for winter and summer conditions. Follow these rules and everything will be fine.
Check your metrics periodically. Even if a couple of days ago the pressure was normal, today the wheel will lose some air. In summer, it is recommended to check once every 1-1.5 weeks. When operating the vehicle in winter and on bad road conditions, the check is carried out once every 5 days.
If your tires are overinflated beyond the recommended levels, be sure to deflate the excess air. This is easy to do. The cap is unscrewed from the nipple and the valve pin is pressed. Many pressure gauges have a special element that makes it convenient to press this pin and instantly check the updated readings.
Warped rims lose air faster, so they will have to be pumped up more often. Therefore, if it is not possible to replace the wheels, try checking with a pressure gauge and inflating your tires every 2-3 days.

Many modern cars are equipped from the factory with tire pressure sensors, which greatly simplifies monitoring tasks for drivers. They will be able to tell you when your low-pressure tires are underinflated or have received too much air during the inflation process.

If you think that overinflating a tire is better than underinflating it, you are seriously mistaken. There is only one correct pressure - the optimal one specifically for your car, provided by the automaker.

Everything else is over-pumping or under-pumping. For a passenger car, like a truck or other vehicle with wheels, both options pose a certain threat.

Underpumping

If the tires on your car are not filled enough with air, then:

fuel consumption will increase;
the dynamics of the vehicle will decrease;
the rubber will heat up faster;
The wheels will start to wear out faster;
the likelihood of the car drifting or skidding will increase;
high probability of disassembly;
The quality of control decreases, the steering wheel commands become worse.

As you can see, everything is very serious. Therefore, make sure that the pressure is normal.

Pumping

There are situations when car owners overinflate the tires on their cars. Moreover, this often happens due to simple laziness to bleed off excess air by holding the valve for a few seconds.

But such situations have unpleasant consequences:

there is a high probability of a hernia appearing on the tires (especially if the roads are of dubious quality, of which there are many in our country);
the process of erasing the rubber tread (its central part) is accelerated;
the contact patch with the road becomes smaller, which causes the level of adhesion to deteriorate;
the load on the chassis of the vehicle increases;
background noise increases while driving;
the car becomes less smooth;
on every bump you literally jump (with a strong jump, the driver can simply take his hands off the steering wheel and lose control).

And there is nothing good here. Therefore, too high blood pressure is also evil.

Be sure to periodically check the tire pressure parameters and adjust it according to the recommendations for the technical operation of your particular vehicle. The optimal pressure is affected by the make, model, engine type, wheel size, etc. The tables and tips provided will help you with this.

TOP-8 modifications of UAZ Farmer by technical characteristics

The small-sized UAZ Farmer truck is designed to transport cargo weighing up to 1150 kg and 5-7 people. The machine is equipped with an on-board platform and a 2-row cabin, and is used by private agriculture and public utilities. The use of all-wheel drive allows you to deliver repair crews and various loads along country roads and off-road.

Specifications

All modifications of the car are built on a frame chassis with 2 wheelbase options. The trucks are equipped with a 4-5-speed synchronized gearbox and a 2-speed transfer gearbox. Standard drive axles are borrowed from the UAZ-452; some vehicles produced after 2015 are equipped with Spicer units equipped with a differential locking clutch (only for the rear axle).

The 2022 model year UAZ Farmer car is no different in appearance from its predecessors. The car is equipped with an in-line 4-cylinder engine with a distributed fuel injection system. The engine is equipped with forced liquid cooling and develops a power of 112 hp.

The use of an engine with an injector made it possible to simplify the starting procedure. The car began to consume 20-30% less gasoline, but it requires fuel with an octane rating of at least A92. Fuel consumption on the UAZ-3909 depends on the model of the installed engine, and is in the range of 13.5-17.5 liters per 100 km.

The UAZ tank volume is 50 liters, so an additional tank is installed on board, designed to hold 27 liters of fuel. Some models have larger volume tanks. Due to design features, the filling volumes of UAZ tanks are 2-3 liters less than full. Fuel is supplied by a mechanical or electrically driven pump. A filter is installed in the lines to clean the liquid; versions with an injector are equipped with a gasoline vapor trap.

The electrical circuit of all modifications is built on a 1-wire principle; the car body is used as a negative conductor. The voltage sources are a battery and an alternator equipped with a rectifier module. To protect electrical circuits from short circuits, several mounting blocks with fuses are installed, and there is a reusable bimetallic insert. Additional equipment can be equipped with separate protective elements installed inside the unit.

UAZ-390944

The UAZ-390944 vehicle is equipped with a 5-seater cabin and a cargo platform designed for a load of 700 kg. A chassis with a base increased to 2550 mm is used. The total weight of the truck reaches 3050 kg, while the vehicle can accelerate to 110 km/h and consumes 17.5 liters of gasoline per 100 km. The cabin has a standard heater; an additional device for the rear row of seats was not installed. The fuel supply is stored in 1 tank, designed for 50 liters. Additional tanks were not installed by the factory.

UAZ-390994

The closed all-metal UAZ-390994 is built on a chassis with a standard base (2300 mm). There are 7 seats inside (including the driver's). The cargo compartment, separated from the passenger cabin by a bulkhead, is designed to accommodate 1000 kg of cargo. The machines used the UMZ-4213 power unit, which meets Euro-3 environmental standards. With a displacement of 2.89 liters, the engine develops power of 106 hp.

The vehicles are equipped with a 4-speed gearbox, allowing up to 40% of the engine power to be taken out when parked and while driving. For this purpose, the installation of a special gearbox is used, which was agreed upon with the manufacturer. Some vehicles used a front axle with the ability to disable the drive. The trucks were equipped with drum brakes and an additional mechanically operated parking brake. The steering drive was built according to the globoidal worm - 2-ridge roller scheme, and was not equipped with an amplifier.

UAZ-33094

The utility vehicle is equipped with a 112-horsepower ZMZ-409 engine equipped with distributed fuel injection. The vehicle has an increased carrying capacity of up to 1075 kg, but the use of a powerful motor made it possible to increase the maximum speed to 115 km/h. To cool the engine, forced fluid pumping is used using a pump. A thermostat is installed to maintain the set temperature. The interior heating system is connected to the cooling jacket.

On later production cars, an improved braking system with disc mechanisms on the front axle began to be used. Some trucks are equipped with an electronic anti-lock braking system. The rear axle retains drum mechanisms with automatic clearance adjustment.

The standard equipment of the first production vehicles included a tank with a capacity of 56 liters, the capacity of which was considered insufficient. The plant introduced the installation of an additional tank designed for 27 liters of gasoline. The tanks are connected by lines and equipped with individual liquid quantity meters.

UAZ-390942

The UAZ-390942 is distinguished by the installation of a platform with a loading height reduced by 100 mm. The design of the unit uses a wooden floor and folding metal sides. The plant installed ZMZ and UMZ carburetor engines on the vehicles, which accelerated the truck to a speed of 105 km/h.

The tank volume has been increased to 112 liters, which ensures a range of more than 600 km in urban conditions. The containers have a unified design and are located on the sides of the frame under the loading platform.

UAZ-390902

The universal cargo van UAZ-390902 is designed to transport 7 passengers and 450 kg of luggage. The cargo compartment is separated from the passenger compartment by a metal partition equipped with a window.

The cars were supplied with a 75-horsepower carburetor engine designed to use A76 gasoline. In urban driving mode, fuel consumption per 100 km is 16.5 liters. The minibus has a total weight of 2820 kg and is capable of accelerating to a speed of 110 km/h. Drum-type brake mechanisms, hydraulic pad drive. The drive design includes a hydraulic vacuum booster located under the radiator trim.

Gearbox: the right choice for UAZ

UAZ gearbox

Many owners of domestic cars often encounter malfunctions in the gearbox on their UAZ. But the Russian person is designed in such a way that he always prefers to postpone repairs until later. As a result, the UAZ gearbox lever often begins to act up.

The rumble of gears is constantly heard from the transmission, and sometimes the box stops responding altogether. It's time to start repairing it or replacing it with a more advanced one, for example, an ADS checkpoint or a Daimos checkpoint.

Five-speed gearbox for UAZ Patriot

The Russian organization Avtodetal-Service (ADS) specializes in the production of gearboxes for UAZ vehicles. The 5-speed ADS Expert gearbox is supplied to the Ulyanovsk Automobile Plant, where it is equipped with current models of domestic SUVs. It is a one-piece crankcase and is synchronized in all frontal gears.

The gearbox is equipped with both a spur and helical transfer case. Modern ADS Expert boxes have the following features.

By increasing the length of the gear shift lever, the gearbox mechanisms function more smoothly.
The redesigned transfer case rod is equipped with a handbrake return spring mounting bracket, making it much easier to assemble the transmission during installation.
The general design of the gearbox and the selective gear change device have changed somewhat. This made it possible to prevent oil leakage and protect the gearbox casing from the penetration of earth and water.
A special sensor is built into the design, which ensures uninterrupted power supply to the rear lights.
The filling hole of the gearbox chamber is shifted 2 cm lower. This is done to improve oil circulation inside the gearbox. It is completely prevented from getting into the transfer case.

In addition to ADS Expert, in 2013 an improved version of the gearbox from the Daimos company, based on electric control, was developed for the UAZ Patriot. This made it possible to completely eliminate the use of the RCP lever. Instead, a special washer is built in. The rear propeller shaft has also changed: it has been shortened and the intermediate support has been removed.

Transmission repair

The 5-speed Daimos gearbox is also suitable for other UAZ models, which include Simbir, Hunter and UAZ-3160.

To install a new type gearbox on the UAZ Hunter, you will need to change the floor hatches of the car body to more modern ones. The remaining 2 car models will require a little modernization, since it is necessary to cut a hole in the floor for the gearbox lever.

When carrying out installation work, qualified assistance will be needed, so it is recommended to entrust the replacement of the gearbox to a licensed service station.

If you want to replace some gearbox parts yourself, use the instructions provided for complete disassembly and reassembly of a UAZ gearbox. In this case, repairs can be carried out without the use of a lift and outside help.

Necessary tools and preparatory work

Dismantling the UAZ gearbox will require the following tools and materials:

a set of open-end and socket wrenches in sizes from 10 to 36;
a special wrench for tightening flattened nuts (you can use a bicycle wrench);
a set of Phillips and flat screwdrivers;
service key with straight and curved ends (pliers);
copper synchronizer or rod for working with gears;
a small piece of metal pipe to hold keys when screwing nuts in hard-to-reach places;
core chisel and heavy hammer;
set of gaskets for UAZ gearbox;
high-quality sealant that will be used to install gaskets.

When choosing a set of keys, it is important that they are as compact and thin as possible. Most fasteners are in an inconvenient position for dismantling, so choosing the right keys will save you time and nerves.

Owner reviews and how much it costs

Despite the start of production of Pro series bonneted trucks based on components of the Patriot SUV, the production of cars of the previous generation did not stop. The simplified design of vehicles developed in the 60s has a positive effect on the price - the cost of a new UAZ-390944 starts from 697 thousand rubles. At the buyer's request, heated front seats are installed on the car; this option costs 7 thousand rubles. The plant does not offer any other add-ons.

Used Farmer cars that are in good condition are valued by their owners at 300-350 thousand. On the secondary market there are cars equipped at the factory with a diesel engine. The use of such a power unit reduced the cost of cargo transportation, but the equipment did not become popular among owners. The price of such vehicles is no different from the cost of gasoline all-terrain vehicles.

Alexey, Kostroma region

The Farmer bought a car for trips into nature and delivery of small loads to a country house. The rear row of seats can be folded into a bed. The vehicle's maneuverability through mud and uneven country roads is good. The disadvantage is that the engine is located inside the cabin; it gets hot in the summer. In winter, the hood serves as an additional heater, but only after the power unit has warmed up. There is no comfort for the driver and passengers; the all-terrain vehicle is unsuitable for long trips.

There are 2 cars at work that differ in transmission. The version with a 5-speed gearbox is more economical, the acceleration dynamics are no different from the 4-speed model. The metal of the body and frame is poorly painted; corrosion appears on new cars after 6-8 months of operation. The car drives on any road; only an inexperienced driver can get stuck.

UAZ farmer tuning salon

Owners tune the car not only outside, but also inside. To use the car in bad weather conditions:

The surfaces in the cabin are covered with easy-to-clean materials. This allows you to quickly clean any contaminants that have appeared;
Install a hatch on the roof of the cabin. This allows for improved ventilation in the cabin in the summer;
To increase comfort in the cold season, the heating system is being modified. To do this, install more powerful electric heater fan motors;
The cabin and body are equipped with places for short-term living or eating. This allows you to use the UAZ 39094 as a motor home;
Install sound insulation. It allows you to reduce the noise level emanating during operation of the power unit and the vehicle's chassis system. This reduces the level of fatigue of the driver and passengers during long trips.

From the above it follows that the UAZ 39094 car is a high-quality domestically produced car. The vehicle has high cross-country ability. UAZ is unpretentious to the conditions of use and is easy to repair.

2018 UAZ 220695 “Loaf”.
