Now many shinomontazhkah offer instead of air to pump up the tires with nitrogen. service stations masters claim it gives a number of advantages. They attribute this to the fact that the nitrogen molecule is larger oxygen molecule that reduces leakage through the surface of the tire; it keeps a stable pressure even when the temperature changes, and also avoids corrosion of the inner surface of the disk and the metallic elements tire cord.
Let's see whether the pumping of tires with nitrogen actually promises a number of operational benefits, or the service is meaningless.
A bit of physics.Tire pressure injected nitrogen not be more stable under changing temperature than in conventional air injected. To understand this is enough to remember high-school physics, since the coefficient of thermal expansion is the same for all gases. And the weight of 1 m3 of nitrogen (at 0 ° C and a pressure of about 100 kPa) less than that of "cube" air only at 25 g. Therefore, tires inflated with nitrogen, it is easier for a few hundredths of a gram, and you definitely will not feel any difference in the driving comfort on normal roads. This makes sense only for professional racing drivers in Formula 1, for which the value of each unit of measure.
Are there any advantages? automotive technicians assure us that ride on wheels, the injected nitrogen comfortable. To do this, they use a simple trick. You to feel the softness of driving, they just pumped up the tire a few tenths of an atmosphere less. In fact, no difference in the running characteristics of the tire inflated with nitrogen does not exist.
Also myth is the view of wear resistance of the wheels, since nitrogen saves metal elements tire cord corrosion. The fact that they are hidden in a layer of rubber and are not in contact with air.
One of the statements in favor of the nitrogen that they inflated the tire never blown away. In fact, the wheel would be lower matter than is uploaded, if the faulty valve, leaking tire, worn, punctures and damage. Therefore regularly check the tire pressure is necessary in any case.
What really matters?
No matter what your tires are properly inflated, it is important to regularly check the pressure in them as low leads to the following consequences:
• Reduction of exchange rate stability,
• reducing traction on wet roads,
• Hypersensitivity to the dangerous road factors,
• reducing tread life,
• an increase in fuel consumption,
• reduction of life of the tire due to excessive heat release due to excessive deformation.
