Why do not ride on the thrown wheels. What is dangerous carbon tires

It is believed that riding with pumped tires leads to fuel economy. And except for saving special problems for use.

Normal and recommended pressure is indicated in the instruction manual for your car and duplicated on the driver table plate

If you roll the wheel by adding 0.5 to normal pressure, fuel consumption will decrease to 0.2 per 100km

If you roll the wheel by adding 1 atmosphere to normal pressure, fuel consumption will decrease to 0.4 per 100km.

On the pured rubber there is severe wear, as the rubber is loosely adjacent to the asphalt. Under normal pressure, the service life of 80-120 thousand runs, with an increase in the pressure in the tire +0.5, the tire life of about 40-60 thousand runs, with an increase in 1 atmosphere there will be premature wear of rubber, which is enough for only 25-30 thousand. Run.

Plus, the excessive pressure is influenced by comfortable driving, a decrease in the clutch with a road surface, which entails the premature replacement of the suspension elements.

Not pressed wheels By 0.5 atmosphere entails an increased fuel consumption to 0.7 liters per 100 km, strong wear of the side tread, the acceleration speaker decreases. There is a risk that when entering the yam, rubber can fly from the disk. Pluses are not so much, but they are present, more comfortable movement and reducing the brake path by 10%.

Do not save on matches, swing the wheels of the values \u200b\u200bspecified by the manufacturer and follow the tire pressure.

The people in Russia lives very inquisitive, incredulous and inclined to experiments. Take, for example, the Germans. If there is an instruction manual for technology, the German will be carefully, punctually follow its recommendations. Our person, most likely, will not even read the instructions to the end. It is much more interesting for him to experiment, touch with his hands, come up with some kind of know-how.

Therefore, a car for our fellow citizens is a real find, with which you can show all the power of your intelligence. For the year that year in the environment of motorists in the go, such a bike, that if you lose the pressure in the wheels of your car on the floor-atmosphere from the norm, then the smoothness of the move will improve the tires to the same half-atmosphere, then the car will seriously save fuel .

In fact, if you lose the air pressure in the wheels on the floor atmosphere, then the following will be. Yes, the car will ride much more. It will noticeably become small choicing, cracks, and larger irregularities on the road a car is much easier. This is due to the fact that the tires, losing the half-atmosphere, became softer.

In addition, it is possible to note the fact that the car, on a straight line, will become much more, and the brake reaction is significantly improved. This effect is explained very simply - the area of \u200b\u200btread contact with the road surface will increase, which means the tire clutch area will become more.

However, all these advantages are very quickly turned into minus when we pay attention to the fact that the fuel consumption increases. Let be insignificant (about 2%), but still unpleasant. Seriously worsen course stability car. Much harder to manage the car. But this is already serious. So before the accident not far. Why then give you the smoothness? In addition, unchanging tires begin to wear quickly at the edges.

Well, and if, pump the tires to the half-atmosphere, then the machine will slightly save fuel (about 1.6%), as well as a slightly improved car handling at low speeds. Tires slow down normally, but it will be much more difficult to stay on the verge of Uza.

However, there are also serious disadvantages. Due to the fact that the tire clutch area with an expensive decrease is reset the vehicle speed and controllability is significantly worse fast RideSince the driver begins much worse to "feel" the steering wheel.

In addition, the tires are started to respond sharply to all the irregularities of the roadway, turning the trip to the car in the car to real torture. Do you need it? Especially since the tire wear will be seriously affected by the tread.

The conclusion from the foregoing is pretty simple - the tires with the deviation of the pressure in one or another side significantly worsen the consumer properties of the machine, not to mention the fact that the wear of your car rubber is sharply increasing. It is especially dangerous to prepand the tires, as it is fraught with the creation of an emergency.

Therefore, using high-quality tires of well-known manufacturers (Bfgoodrich, Bridgestone, Continental, Dunlop, Gislaved, Goodyear, Kleber, Michelin, Nokian, Pirelli, Yokohama), maintain a normal (recommended by the manufacturer) the pressure of your car.

Tire pressure is a very important thing for which every motorist should follow. Otherwise, there is a risk of earning a whole wolf of a variety of problems. And this is not to mention that incorrect pressure In tires can easily cause a traffic accident. It's time to take a closer look at this question and clearly determine which problems and consequences may be.
Unfortunately, not every driver thinks about how the tire pressure really should be. The car's operation manual indicates two values \u200b\u200b- with full and on partial load. Practice shows that the overwhelming majority of drivers know only one of these numbers (most often the pressure indicator during partial load) and absolutely not think about the second. But it has to face it constantly. As the result of all this is a violation of the pump pumping level.
Overpressure in tires can be very dangerous. At elevated tire pressure becomes more rigid. On the one hand, it is easier to roll. However, at the same time, it loses a significant part of its potential for adhesion with the road. In addition, when such a tire hit, the risk of damage increases significantly, the load on body elements and suspension is growing.
Interesting fact: In addition to the total rigid tire, it creates more noise in the cabin and brings significant discomfort when controlling vehicle. If the tire pressure is insufficient, then another set of problems arises. The tire wear is significantly accelerated (if the pressure is below the norm by 20%, the tires are extended by 25-30% faster). Everything also drops the grip of the wheels with the road, significantly grows the consumption of fuel. Finally, in the most running cases, damage to the wheel frame is possible. All this can cause an accident on the road.
Interesting fact: Not so long ago, the group of enthusiasts decided to show what will happen to the car, if a significantly rush the tire. It may be difficult to believe, but a radical increase in the pressure in the wheel turns it into a bomb. The effects of the explosion of the wheels can be very destructive. Even if damage was twice as fewer than you can see in the video, imagine that such a tire would make it in its place.

Specialists involved in the study of tire characteristics and the design of new models have long defined an interesting dependence. An increase of 2.0-2.5 bar in the operating pressure range of 2.0-2.5 bars leads to a decrease in rolling resistance by 5%. This is because, with an increase in pressure, the radial deformation of the tire is reduced due to the increase in its rigidity. And smaller deformations unequivocally reduce hysteresis losses in the rubber layer and Cord. But note that the tire rolling resistance is only part of the full resistance that the car is experiencing when driving.

Resistance to the movement of the car in the general case is provided:

• The power of resistance to rolling all the wheels.This parameter smoothly increases with an increase in the speed of the machine.
• Air resistance force. Air resistance depends on the velocity of the machine, the cross-sectional area of \u200b\u200bthe car and the coefficient of aerodynamic resistance. The dependence on the speed is quadratic, that is, imperceptible at low speeds of air resistance as overclocking absorbs the lion's share.
• The power of resistance acceleration.The car is very rarely riding evenly and straight. Road conditions Forced to reduce speed and then increase it. The described force is proportional to the mass and acceleration with which the car moves. Accordingly, the more you downloaded your car and start tacious from traffic lights, the greater the resistance will have to overcome.
• The power of resistance to the movement on the rise.This force is essential when the car has to move in a mountainous area with frequent lifts and descents, and the movement is not possible by security conditions.

But before a long expensive, when a movement with high speeds on highways is assumed, factory instructions are often even recommended to increase the pressure by 0.2-0.3 bars. Upon reasonable speeds, this will reduce tire heating, increase their resource and save some fuel. At the same time, the savings will not exceed 3%. It is not advised to increase the pressure on a large amount, because the chassis of the car will exceed the effect of fuel economy, and the car will become tough as a cart. Safety is also injured, because the stability and manageability of the car will be far from settlement, and simply from your usual.
