With the correct air pressure, your tires will perform better, be more resistant to wear, and will also be more fuel efficient. The "correct" air pressure for original tires or tire sizes is specified by the manufacturer vehicle and may differ for front and rear tires. Contact your Toyo distributor or dealer to determine whether the replacement tires on your vehicle are the same size as the original tires.

Where to find information about the correct pressure in the original tire

You can find the recommended pressure on a placard or sticker near the door limit switch, in the glove compartment, or on the lid. fuel tank. If your vehicle is missing a decal, consult your owner's manual or the vehicle manufacturer, tire manufacturer, or your tire dealer. The inscription on the tire informs you about maximum load vehicle, cold tire pressure and tire size as recommended by the vehicle manufacturer.

Using a tire pressure gauge

Based solely on visual inspection, it is impossible to determine whether a tire is low or underinflated. Always use the exact one tire pressure gauge to determine tire pressure.

When to check tire pressure

Check the tire pressure (including the spare tire) at least once a month or before a long trip. Tires should be inspected cold (before they've been driven a mile). If you need to drive more than a mile, measure and record the underinflation in each tire. Upon arrival at the station Maintenance measure the pressure in each tire again and, if the pressure has increased, adjust required pressure air. For example, if the cold pressure should be 35 psi. inch, and was equal to 28 psi. inch, while the pressure is currently 33 psi. inch, you should inflate your tires to 40 psi. inch and check them again when cold.

How is tire pressure reduced?

Tire pressure decreases naturally as a result of the permeation process. Changes in outside temperature can affect the rate at which tires lose air. This change occurs more often in hot weather. IN general outline, tire pressure decreases by one or two pounds per month. cold weather and even more so in hot weather. Remember that under-inflation is the leading cause of tire failure, so check your tire pressure regularly.

Other useful tips

Never release or reduce pressure on hot tires. Pressure is characterized by an increase while the vehicle is moving.

Make sure that all tire valves and extensions have caps with rubber gaskets to protect them from dirt and moisture. When replacing a tire, always use a new bar assembly.

At insufficient pressure or overload, overheating occurs which may cause the tire to fail, which in turn may result in vehicle failure and/or serious injury or death.

In today's lesson we will learn how to ride on muddy AT tires and use its tread pattern to reliable grip with slippery clay. Let's define optimal pressure in tires and indicate the correct actions of the driver in difficult off-road situations

Let’s say you miraculously managed to find time to go fishing or, God forbid, it’s time to take your family to the dacha. But it had rained the day before, and the road was pretty rough... This is the type of off-road that most owners of crossovers and SUVs most often encounter. At the same time, as we already told in the last lesson, good fatty clay sometimes clogs even the “evil” tread of mud tires, and not everyone is ready to lift the car and equip it with toothy MT tires for the sake of traveling on a muddy track two or three times a year. Yes, in general, this is not necessary. To enhance the off-road capabilities of a vehicle, most of which travels on paved roads, there are All tires Terrain (AT).

As a visual aid, we use the tire of our partner – Toyo Open Country AT Plus. Its tread looks like a regular road one. But if you look closely, you will notice that the outer shoulder is much more aggressive than the inner one. Moreover, the tread extends onto the sidewall of the tire. What does this mean? That the tire can be safely used in mud. Taking into account the ground clearance of your car, of course. That is, if timber trucks weren’t driving along the dirt road before you appeared, but still Cars, then you will most likely be able to overcome it without problems on AT tires.

Reducing tire pressure even to 1.0 atm is significant
increases its off-road capabilities

WHERE TO BEGIN?

Firstly, the tire pressure should be reduced, and before you start attacking the mud. If the car is already stuck, this usually does not help. Of course, unlike MT mud tires, in which we reduced the pressure to negligible values, in the case of AT we do not recommend doing such a radical thing. Because ordinary road wheels Your car at such low pressure will most likely not be supported by the tires, and the wheels can easily come apart, which will significantly increase the number of your problems. Therefore, we reduce the pressure to 1.0 atm on light SUVs and crossovers, to 1.2 on heavy ones, and to 1.5 on very heavy ones. For this purpose, you should definitely carry a pressure gauge and a compressor with you in your car, especially since they will be useful not only in this situation. Reducing the pressure, as we said earlier, not only increases the contact area - the tire becomes more elastic, better adapting to the folds of the ground, and crawls over obstacles like a caterpillar. In this case, the sidewall flattens out, turning into part of the tread. Now it’s clear why you need a pattern on the sidewall? Thus, reducing the pressure allows you to more effectively use the advanced technologies embedded in the tire design.

It is better to let the ruts pass between the wheels. As a last resort,
you can dump the car into one track from the outside

But this does not mean that by installing AT tires and reducing the pressure in them, you will ride on dirt as on asphalt. You need to keep in mind that, as we already wrote in the previous lesson, deep ruts and ruts generally need to be passed between the wheels. Because in ruts, your car can simply run aground on its “belly,” like a large ship running aground. If the road is narrow and there is no way to keep the track between the wheels, you can try to dump the car into it on one side only. This will leave a margin of ground clearance and allow you to move even on deep ruts. Although it’s still not worth driving on ruts in a regular crossover or SUV - there is a high probability of damaging the car by taking water into the engine in bottomless puddles.

For AT, the methods of moving in a rut, outlined in the previous lesson, are also relevant. If you are driving on virgin soil, laying a new track in the mud, the resistance to movement at this moment increases noticeably. The car begins to slip, and the speed drops rapidly. In this case, decisively turning the steering wheel half a turn left and right helps a lot. This, firstly, will allow the front wheels to push the dirt in front of them and, secondly, to more actively cling to the sidewall of the tread, which is more aggressive than the middle. Now about the clay. What is the main difference in the behavior of AT and MT rubber when driving on clay? Remember in the last lesson we said that mud tires doesn't like slipping? This can lead to even more digging. So, AT rubber, on the contrary, often allows you to overcome a particularly difficult section with the help of slipping. Its tread is not so aggressive and does not bury the car in the ground in one wheel rotation. Moreover, the opposite often happens, and the high rotation speed of the wheel throws dirt out of the tread, providing good traction. But there is one “but” here - don’t overdo it! We recommend accelerating in strictly measured doses - in pulsations: by pressing the gas pedal and spinning the wheels, releasing the pedal and then pressing it again. This method allows you to find optimal speed rotation of the wheels, at which maximum grip is achieved. It is especially effective in combination with active work driving.

Intensive work with the steering wheel helps to move apart
dirt when laying a new track in virgin soil

Lower tire pressure helps the tread shed dirt

If the clay is slippery, but not deep, then the slipping car will move strongly from side to side. To avoid uncontrolled sliding, we recommend that you accelerate into the highest possible gear. Due to the increased load on the engine, a high gear will eliminate excess torque on the wheels. Yes, if the car is equipped with traction control systems, it is better to turn them off before driving through mud, otherwise they may well do you a disservice: for example, at the wrong moment you let off the gas, deciding that the car is slipping. You should also avoid active braking, because on a slippery surface the wheels may lock and the car will lose control. In addition, if there is a need to fit into a turn, it is better not to brake, but to actively work with the steering wheel and the gas pedal. On slippery clay, this will give you the opportunity to at least somehow turn. And it is better to reduce the speed by using engine braking and releasing the gas.

Good mud reliably clogs any tread

Slip helps to throw dirt out of the tread

So, before overcoming clayey areas, first of all, reduce the pressure and turn off traction control system. When overcoming obstacles, actively use the steering wheel and not too actively use the gas. If possible, switch to top gear. When driving onto a paved area, be sure to restore your tire pressure to normal and turn on previously disabled systems again. Knock off clods of dirt stuck to wheel disks, especially from the inside, or better yet, wash them at a car wash. Lumps of clay cause a noticeable imbalance and can cause the steering wheel to “beat” at speed, and the car itself to vibrate. And remember: even such modern tires, like the Toyo Open Country AT Plus, only guarantee half the success. The second necessary part is your experience and competent actions.

The outer, more aggressive part of the tread, together with the sidewall, provides increased grip

Japanese manufacturers produce tires that have become very popular among owners fast cars, as well as luxury cars. Toyo tires differ from similar ones in improved parameters and properties. Not good high price made them available to many car enthusiasts. They are produced in several series. Each model is designed for specific purposes.

Which tires are better: Dunlop or Toyo?

These companies have long been known to motorists. Each model is considered the best in its class. It is simply impossible to say unequivocally which tire is better. The characteristics of the tires are so good that it is very difficult to give preference to one of them.

Toyo or Yokohama?

Most Popular Japanese tires Yokohama remains in Russia. The range of models is so diverse that they are installed on passenger cars and freight transport. A feature is considered to be fairly good grip and a comfortable ride.

Car owners respond differently to these tires. Some consider them very good, while others consider them unsuccessful. Some parameters of Yokohama are inferior to Toyo.

However, it is also impossible to responsibly state that Toyo is better. Each model has its own disadvantages and positive sides. We can only say with confidence that both of these models are reliable and safe.

Hand on heart, how often do you check your tire pressure? Do you even know what the optimal air pressure in your tires should be? Did you know that when the car is heavily loaded, the tire pressure needs to be changed? Not only because the tires wear out less this way, but also to reduce fuel consumption.

You need to check the air pressure in your tires every two weeks, if possible, when the tires are cold (that is, not after you have driven several tens of kilometers), do not forget to check the pressure in the spare tire. If the pressure is too low, there is a risk of damage to the wheel (as it becomes hotter during use). In addition, wear increases. As tire pressure decreases, so do ride quality. You can safely inflate your tires 0.2 bar more than is prescribed in the instructions for your car - since manufacturers, as a rule, indicate as the recommended minimum permissible pressure that provides the most comfortable driving. By increasing the air pressure by 0.2 bar, you will reduce fuel consumption.

Information about the recommended tire pressure for your vehicle can be found in your vehicle's owner's manual, or sometimes on the gas cap or door.

If you find that your tire is missing a valve cap, replace it as soon as possible (these are small rubber caps that cover the hole for pumping air).

If you have two cars, and you drive one much less often, do not forget to check the air pressure in the tires. If you are idle for a long time, change the parking place from time to time, otherwise an imbalance may appear in the tires - from standing in one place for a long time and the constant impact of the vehicle’s weight on the same section of the tread, they will lose their round shape.

Copying and publication of news is permitted with reference to

Tires under the Toyo brand are produced Japanese company TOYO TIRES, which celebrated its seventieth anniversary last year. The company develops, produces and markets tires with superior performance characteristics. The range of products produced is extremely diverse. It includes summer and Winter tires for almost any vehicle, from multi-ton trucks to cars. What should be the pressure in Toyo tires, we will consider in this article.

Toyo tire production

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!

Production of Toyo tires is carried out on the basis advanced technologies, which are based on safety and ecology. One of these technologies is computer modeling, which is used to analyze the main parameters (noise, internal stresses, water-repellent properties, rolling coefficient, etc.). Product testing is carried out at the technology center in Itami and at two test sites (on the islands of Hokkaido and Kyushu). TOYO TIRES company has production capacity in 8 countries, and its representative offices are scattered throughout the world.

Models and sizes of Toyo tires

The toyo tire product line is truly impressive. There is no point in presenting it in full here - it is present on the company’s official website, with pictures and prices. There it is easy to select the modification you need by entering the appropriate parameters for your car. In general terms the lineup TOYO TIRES products are as follows:

• Summer tires are represented by 18 modifications, half of which belong to the Toyo Proxes brand;
• Winter tires are represented by 14 modifications, of which only one is studded. There is a trend towards studless tires, which cause less damage to the road surface.

Standard sizes vary within the following limits:

• width – from 185 to 275 mm;
• profile proportionality – from 30 to 70%;
• landing diameter – from 14 to 24 inches;
• load index – from 60 to 129 (from 250 to 1850 kg);
• number of speed indexes – 16 (from 100 to 300 km/h).

Such a rich variety can satisfy almost any consumer who operates a vehicle in any climatic and weather conditions.

What should the pressure be?

The nominal air pressure in tires, as well as their permissible standard sizes, are given by the vehicle manufacturer in technical documentation and on special plates or stickers, mostly located on the car door or gas tank cap. The maximum permissible pressure is shown in front side tires. If you have any doubts, you can contact official dealer Shin Toyo and receive the necessary clarification.

Maintaining correct tire pressure:

• provides maximum safe driving due to the best adhesion of the tire to the road surface;
• reduces wear (and therefore extends the service life) of the tread due to rational load distribution;
• saves fuel as it provides minimal rolling resistance.

As a rule, pressure in the anterior and rear tires slightly different, which is due to the uneven distribution of load along the axes motor vehicle. Moreover, sometimes situations arise when it is advisable to reduce the tire pressure. For example, if you have to overcome a sandy or swampy area. In order not to dig into the ground, the adhesion area with the ground should be maximized, which is achieved by relieving pressure. To what extent is difficult to say, it all depends on personal experience driver. The main thing is not to forget to restore the pressure as soon as the difficult section is passed.

What and how to measure pressure

The air pressure in tires is in the vast majority of cases measured by a device called a pressure gauge. It can either be in the form of an independent device (for express testing) or be a component of an inflating device (electric compressor or mechanical pump). It is enough to press the separate device firmly against the mouth of the nipple for a short time. The pressure gauge included in the pump shows the pressure immediately after connecting the pump hose to the nipple.

Manipulation of pressure measurement must be carried out on cold tires, otherwise you can get a distorted result. For example, when you drive up to a gas station or tire shop to check the pressure or pump up the tires, pause for 15-20 minutes, relax, listen to music.

There are also sensors in the form of indicator caps. They screw onto nipples tubeless tires and signal with color or sound a drop in air pressure. But it's still exotic. Nothing better than a dial pressure gauge has yet been invented.

Pressure on a pressure gauge scale is usually indicated in two units: kilopascals (BAR) or pounds per square inch (PSI). For many drivers, the more familiar index is “atmosphere” (atm.), but the difference between atm. and BAR is so insignificant that it can be neglected.

Since the permissible pressure in toyo tires is in the range of 1.5-3 atm, the table below is compiled specifically for this range.

PSI	21	23	25	27	29	31	33	35	37	39	41	43	45
BAR	1,45	1,59	1,72	1,86	2,00	2,14	2,28	2,41	2,56	2,69	2,83	2,97	3,10

Regularity of Toyo tire pressure monitoring

If you find yourself in a remote area far from civilization, and even without a pressure gauge, the degree of tire inflation can be assessed visually by appearance tread. If after a long time drive fast On dry roads, the central part of the tread appears lighter, which indicates that the tire pressure is too low.

Practice shows that it is advisable to check tire pressure every two weeks or after every 1,500 km. IN winter period It is better to do this check more often, since a decrease in temperature by 10 degrees Celsius can change the pressure by 0.1 atm. It goes without saying what needs to be done visual inspection wheels before each trip, as there is a chance that the day before you “caught” a nail or bolt. You may not notice this right away, since these nasty pieces of iron clog the hole so tightly that the bleeding of air can continue all night. And if you are inattentive in the morning, then after driving just a few meters, you can write off the tires as scrap.

Toyo tires hold pressure well. However, no one has yet invented a tire with absolute tightness - no one has yet canceled the law of diffusion. So reducing pressure is a natural and irreversible process. You just need to keep in mind that the speed of this process depends on the temperature: the higher it is, the faster the air leaks in the tire.

What's in the bottom line

Any underinflated, overinflated or unevenly inflated tires, including toyo tires, are fraught with a lot of troubles, and sometimes disaster. This is especially important for multi-ton trucks - loss of controllability here is fraught with catastrophic consequences.

An underinflated tire leads to:

• deterioration in controllability due to increased steering effort;
• increased tread wear;
• increased noise when driving;
• increased roll when turning (pulling to the side).

An overinflated tire leads to:

• deterioration in handling due to reduced adhesion to the road surface;
• increasing braking distance;
• increasing the load on the car suspension;
• the “jumping car” effect.

Uneven tire pressure threatens, among other things, skidding when turning and braking, especially on wet asphalt.

By following the simple rules outlined above, you will ensure yourself a safe and comfortable trip, and the threat of damage to third parties will be significantly reduced. Finally, don't forget to install a new valve when changing a tire; air leaks often occur through this valve.
