Why is it so important to use only correctly inflated tires? From the state it's in wheelbase, not only fuel consumption depends, but also the safety of the driver and passengers during movement. The tire pressure of Renault Duster, Logan or Sandero should always be normal. As a rule, the manufacturer indicates such indicators on the car itself - in the area of \u200b\u200bthe door on the driver's side or in the place of the filling tank.
Car tire pressure gauge In addition to the fact that with properly inflated tires, the car will be operated competently and carefully, the correct use of the entire chassis of your Renault Logan or Duster will be ensured. By the way, this rule applies to all vehicles.
Table of standard tire pressure for Renault Logan cars How to measure pressure correctly
Tire pressure cannot be determined by eye. Outwardly, you can only notice any deformations on the tire itself. This will only work if the vehicle is systematically driven with the wrong air/tire size ratio. Then various deformations are formed on the tread.
It is possible to accurately measure the pressure in the chassis of the Renault Logan or Duster (this also includes Sandero and Scenic) only with the help of special pressure gauges. According to the mechanism of operation, the following types of this equipment are distinguished:
- turnouts;
- electronic.
Mechanical pressure gauge for car tires The most accurate among these devices is considered to be electronic. The error here is no more than 0.05 bar. If you do not plan to perform such procedures systematically, you can use the mechanical type of apparatus. True, such devices can be called accurate only with a stretch.

Standard tire pressure Renault Sandero Pressure standards for Renault
This brand of vehicle is quite peculiar. It is impossible to inflate tires “for all occasions” here. Based on the requirements that are prescribed in the instruction manual. The tire pressure for Renault Logan (Duster, Scenic) should be as follows:
- if the diameter of the disks is 14 cm - 2.0 kgf / cm²;
- with a diameter of 15 cm - 2.1 kgf / cm²;
- at maximum load, 0.2 kgf / cm² must be added to the indicators;
- when using a loaded trailer - increase by 0.8 kgf / cm²;
- when driving on sandy terrain, the pressure must be reduced, but not more than 1 kgf / cm².
Table with standard tire pressure for Renault Scenic It should also be taken into account that when driving on snow or wet roads, the indicators should not change.
Specialists at the service station will not only check correct pressure in the tires of your "Logan" or "Duster", but also pump up or lower it to the optimum condition. There you can also find out exactly what pressure for a particular brand of car is correct.
If you plan to travel long distances, it is better to measure the pressure before the start of the trip or after at least 3 hours have passed since the vehicle came to a complete stop.
Correct pressure measurement
It is necessary to measure the pressure on Renault Logan (the same applies to Duster, Scenic). Taking into account the following conditions:
- only in the "cold" state of the car (for the last 3 hours, the mileage is not more than 1.5 km);
- tires must be cold.
Also take into account that you need to take readings from all 4 wheels. Spare wheel should also be systematically tested.
Table with standard tire pressure for Renault Duster cars Measurement process:
- the protective cap is removed from the manometer;
- by means of a special button, the readings on the device are reset;
- the device is mounted on the bus;
- by pressing the valve, readings are taken.
Based on the readings on the pressure gauge, the tire is pumped up or lowered.
Checking car tire pressure Consequences of incorrect pressure
Why is it important to maintain the correct air volume ratio in a tire? If the pressure is systematically in an incorrect state. The following negative consequences are possible:
- fuel will be spent inappropriately;
- road grip will deteriorate significantly;
- there is a risk that the tire will burst while driving, which will lead to an accident.
In addition, the chassis of the car simply becomes unusable. Agree, the repair of almost the entire wheelbase of the Logan or Duster will be much more expensive than buying a monometer.
If you do not have the opportunity to perform such operations on your own, regular technical inspections of the Renault Duster should be carried out at the service station. The better you treat your vehicle the longer it will last you.
Experienced Renault Duster car owners know that their tire pressure should be 2 atmospheres. Tire pressure should be the same everywhere. rear axle, and on the front, just do not forget about the spare tire. You need to check the level on cold tires, after driving more than 1 hour should pass. Many owners ignore these simple guidelines and over-inflate their tires. Next, we will try to find out what this can lead to.
When to measure the level in the wheels?
When a car manufacturer draws up instructions for the pressure to be pumped into a tire, he implies that it will be measured on “cold” tires, the Renault Duster manufacturer is no exception in this regard.
AT Renault Duster as in other cars there is a table for tire pressure.
It is important to remember that you need to measure the pressure before the trip or 1-2 hours after the trip. In a hot tire, the level will always be higher, but this does not mean that you need to bleed the air, you do not need to do this.
If the air temperature has changed, this is an occasion to check the level of tire pressure. That is, for example, in winter or with the onset of frost, you need to check the pressure in all tires with a pressure gauge. In cold temperatures, the pressure will be lower and here you will need a pump. It is enough to check the level 1 or 2 times a week.
If the instructions are slightly changed
According to some reports, it is also possible to keep high blood pressure. High pressure in Renault Duster helps to save fuel on the highway. But there are limitations, you should not go off-road with such pressure.
Let's conduct an experimental study and inflate tires to 2.3 atmospheres. And we will see these results.
- Gasoline consumption on the highway at a speed (90-105 km / h) is reduced by 4.5% (to control this process, we use a function in the Duster called ECO MODE);
- When driving at such a high speed, the car body begins to shake and “throw” to the side, vibrations appear in the cabin. The noise level also increases significantly, although we used it in our study - a restyled version of the Renault crossover;
- There is also an opinion that with high tire pressure it is better not to go to the track in rainy weather.
Now we have to answer the question, what should be the tire pressure on the Renault Duster to save fuel. You can increase the level in the aisles of + 0.1- + 0.2 atmospheres, but the fuel benefit will be no more than 4 percent, again when driving on the highway at long distances and not in rainy weather. The choice is yours!
Why raise pressure on the Duster?
As the reviews of Renault Duster owners say, they keep the tire pressure figure in the aisles of 2.2 atmospheres, but at the same time they do not plan to move off the asphalt. Owners of 2 liter Duster options do the following: pump tires, and they get 5% savings in gasoline and everyone is happy.
The variant with a 2 liter engine weighs a little more than the car in the initial version, but they increase the level in the wheels not for the weight of the car, but only in order to save on fuel. A two-liter engine consumes more gasoline, which means you need to find a reason to save money.
During operation, the main thing is that the tire pressure on the right and left is the same, especially on the front axle. Be careful, a “skewed” car will not bring you anything good.
You may need it soon, this article will help you make the right choice.
For traffic safety and extending the life of the tires, it is necessary to visually check them before driving, identifying damage (punctures, cuts), remove foreign objects stuck in the tread blocks or between them.
On the outer sidewalls of tires, cracks, scuffs on curbs during unsuccessful parking can occur.
It is necessary to maintain the required pressure in the tires (including the spare wheel), regularly (at least once a month) check it with a pressure gauge and bring it to normal.
The recommended tire pressures are indicated on the label affixed to the end of the left front door.
The plate shows the air pressure values in the tires of the front and rear wheels when driving off the freeway and on the freeway.
Tire pressure plate.
It is also necessary to check the tire pressure when the ambient temperature drops or rises significantly and before driving a long distance.
When driving for a long time, especially at high speed, the tires heat up and the pressure in them increases.
Therefore, air pressure should be checked with cold tires before driving.
If it is not possible to measure the pressure on cold tires, it is necessary to take into account the increase in air pressure in the tires from heating by 0.2-0.3 bar.
To check the pressure...
... unscrew the wheel valve cap ...
... and connect a tire pressure gauge or a pump with a pressure gauge to the valve.
If the pressure is lower than required, we inflate the tire with a tire pump or compressor, controlling the pressure on the pressure gauge.
If the pressure is higher than required, by pressing with a special protrusion of the pressure gauge (or a suitable tool) on the spool, we release air from the tire in small portions and check the pressure.
Tires must be free of bulges, tread separation and damage that exposes the cord.
A worn or damaged tire should be replaced immediately, without waiting for its emergency destruction, with a new one.
It is forbidden to install tires of different models on one axle, as well as tires that do not match the size or load of the car.
The remaining tread height must be at least 1.6 mm.
To control tread wear in its grooves…
... indicators are made in the form of protrusions 1.6 mm high.
The sidewalls of the tires are marked with the letters TWI where the wear indicators are located.
With critical wear on the tread across its entire width, the indicators form noticeable transverse stripes.
You can also check the wear of the tread with a caliper.
For this…
... we lower the depth gauge into the groove in the middle part of the tread (as a rule, the tread wears out faster in this area) and make sure that the tread pattern height is more than 1.6 mm.
To reduce the possibility of error, it is desirable to take measurements at three different points along the circumference of the tire.
If the wear exceeds the maximum allowable, the tires must be replaced.
Regularly check the tightening of the wheel bolts and, if necessary, tighten the bolts.
If vibrations occur while driving on a flat stretch of road in a limited speed range, the wheels must be balanced by a tire shop.
Vibration at all speeds can be caused by patchy tire wear, blistering or other damage, or warped rims.
In addition, vibration may be caused by dirt deposits on rim(especially on inside), so it is necessary to flush the discs periodically.
To even out tire tread wear, the manufacturer recommends regularly rearranging the wheels according to pattern “a” (see figure).
To wear the spare wheel evenly with the rest of the wheels of the car, it is recommended to rearrange the wheels according to the “b” scheme.
Scheme of rearrangement of wheels: a - without taking into account the spare wheel; b - with a spare wheel
The rearrangement of wheels is more convenient to combine with the next maintenance.
When rearranging the wheels, it is recommended to check their balance.
Many of us think about tire pressure twice a year. When a tire fitter, when replacing winter wheels with summer ones (or vice versa), suddenly asks: “How much to pump?”. And really, how much? Everything seems to be simple - any car has a special sticker on the gas tank flap, in the opening of the driver's door or on its end. She gives recommendations for almost all occasions: how much to inflate tires depending on their size, car load, and often on the season.
But it is no coincidence that the master inquired about your opinion. After all, since Soviet times, “life hacks” from experienced people have been walking around garages. They say that if you pump up tires harder, the car will roll easier and eat less fuel. Saving! And if comfort is important, then the tires need to be inflated a little, then without any suspension tuning, the ride will become smoother.
However, for those riders who don’t care about pressure at all, the “soft” option is obtained automatically. Especially now, in the offseason. Let's say they pumped up your tire in warm room or in the sun, and at night it is already almost freezing. The air in the tire "shrinks", the pressure drops. Plus, it gradually evaporates through the rubber micropores, especially if the wheel is not the first freshness. Yes, and the quality of installation plays a role: the tire does not fit snugly to the rim of the disc, the valve is crooked - that's the leak.
That is why automakers recommend that the driver periodically check the pressure in the wheels himself. But there is a catch here too. Usually in the instructions you can find a very vague wording: "check regularly." How about “regularly”? Every day? Or maybe once a month?
How often to check tire pressure?
A crossover popular in Russia acts as a guinea pig Renault Duster, which takes place in the editorial office of "Auto Mail.Ru" long test. To begin with, we drive the car to the underground office parking, where it stands at a temperature of plus 20 degrees all day. In the evening, before leaving, we check the pressure with an accurate digital pressure gauge. Exactly 2 atm - as prescribed by the manufacturer. But Duster spent the night on open parking at the entrance. In the early autumn morning, the thermometer outside the window showed only plus 7 degrees. We go out into the street, again we freeze. In all wheels 1.8 atm - a drop of two "tens"! What if it's freezing?
Well, we pumped up the wheels according to the season and ... forgot? We check. Duster remains alone for a week, and when, after 7 days, the pressure gauge again stuck to the tire valves, the display showed the numbers 1.9 - 1.95 atm. In other words, regardless of temperature fluctuations, there are losses, albeit very small ones.
Conclusion. With stable weather, you should not worry about tire pressure every day. It is enough to check it every 2-3 weeks, depending on the condition and age of the wheels. But in the off-season, it is better not to lose vigilance. In warmer and colder weather, it would be nice"Check with the file cabinet" more often. Let's say weekly.
Here a reasonable question arises - are we driving a nuclear reactor? Why such perfection? Just think, 2-3 "dozens" ... You won't even notice it by eye. About whether this little thing can affect the performance of the car, the second part of our experiment.
If the tire pressure is correct
In order to evaluate the behavior of the car on normal, slightly flat and pumped wheels, we laid a route of about 80 km in the Moscow region. At the same time, it was built with the expectation that on the way we would come across a highway, and ordinary country roads, and winding sections, and city traffic. We left during the day when the traffic is more uniform. Refueled to control fuel consumption always at the same gas station. And even at a strictly defined column - exactly to the neck.
The first round is at the correct pressure of 2 atm. Therefore, I will not begin to paint the habits of the Duster again. Everything is exactly as it was at the time first test in Romania and with features that could be noticed during the run across the Russian expanses. And these are the results. At a distance of 82.2 km, Duster, according to the onboard computer, showed an average consumption of 6.5 liters. But at the same time, 5.8 liters of diesel fuel entered the tank, that is, the electronics slightly cheated, and in fact the crossover ate 7.01 l / 100 km. We will take this figure as a guideline.
If the tires are slightly flat
And now let the tires cool down and release 0.3 atm. Wow! The road is the same, but Duster drove uncertainly. Acceleration is viscous and long, as if the car is dragging a trailer behind it. The steering wheel is padded and damped - you can guess rather than feel about the position of the front wheels. Duster on lowered tires began to hold its course worse, sway more and shy away from gusts of side wind more sharply. And in bundles of turns, I wanted to spit on everything, get out and, finally, pump up the unfortunate tires so that the car gets rid of this dumb “gait”.
The difference in pressure between the tires on the left and right is 0.6 atm. It is almost imperceptible to the eye, but the behavior of the car changes very seriously.But there were also advantages from pressure loss. The smoothness of the ride has increased significantly. Duster already has an elastic undercarriage, and here it turned into a feather bed - it was as if they walked along the tracks with an iron: not a seam, not a joint. In addition, unpleasant bumps on the steering wheel are a thing of the past.
While we were completing the previous round, repairs began at one of the interchanges, so we had to take a detour for the second time and the total mileage increased to 85. Disappointing figures glow on the on-board computer screen - 6.9 l / 100 km. “Some 3 dozens” increased consumption by 6.2% at once! True, the actual topping up showed a slightly more optimistic result. The tank included 6.3 liters of diesel fuel, that is, the real average consumption was 7.41 l / 100 km - plus 5.7%. But still, appreciate the scale of the disaster. Engineers go to unthinkable tricks to make modern models more economical, and here just an oversight of tire pressure crosses out their efforts.
If the tires are slightly inflated
The third approach - we drive the extra 0.3 atm into the tires. By the way, some automakers recommend doing this when driving at high speed or when fully loaded. Now it's clear why. The former agility returned to the Duster during acceleration, the buildup was gone, and during maneuvers, the crossover surprised with the liveliness of the response. But it became prohibitive to shake, vibrations appeared on the body and seats. And the noise level rose to an unpleasant level, as if the restyled Duster was magically changed to the previous one. An error occurred during loading.
Five conclusions from Auto Mail.Ru
- The manufacturer's recommended tire pressure is a compromise. But the compromise is reasonable and should be trusted in most situations.
- Even small fluctuations in tire pressure have a significant impact on fuel consumption.
- The stronger the temperature drops outside, the more often it is worth checking the pressure in the tires. Don't forget the spare! Carry out measurements before a trip, on cold wheels.
- It makes sense to lower the tires slightly if you have to drive on rough roads. Don't forget to bring your blood pressure back up!
- Inflated tires - for "gran-tourism" on highways and transportation of heavy loads. There are savings on fuel, but it is unlikely to pay for the cost of repairing the suspension.
