How many atmospheres in a wheel are considered normal?

Every car has a certain tire pressure rate. As a rule, this rule is indicated on a sticker inside the driver's door, but if there is none there, you can find the functions in the instruction manual (in the manual). It is very important to observe just such a number of atmospheres, because the correct tire pressure is very important to reduce gas mileage and extend the life of your tires.

So, how many atmospheres in a wheel are recommended? Most passenger cars will recommend 32 to 35 pounds per square inch (2.21-2.41 Bars) on the tire when they are cold. Why cold? Because tires are rolling along the road and friction between them and the road generates heat, increasing tire pressure. Do not swing your wheels to the pressure indicated on the tire itself. It indicates the maximum number of atmospheres, and not a recommendation.

Maintaining the right tire pressure helps optimize tire performance and fuel economy.The correct amount of atmospheres in the wheel of the car stabilizes the structure of the tire, mixing the responsiveness of the tire, grip and handling, which allows the driver to experience driving comfort. How many atmospheres in a wheel are shown by special devices - manometers. They are of various types: turnouts, mechanical and electronic. There is, of course, a method of pumping "by eye", but it is, say, not very good, because its accuracy is very willing to demand better, and the actual pressure in tires can differ almost 2 times.

Sometimes drivers do not use recommendations and adhere to general rules - they pump up pressure on the front wheels - 2.2 atmospheres, and on the rear wheels - 2.0. At the same time, when the car is fully loaded, the pressure in them increases to 2.4 atmospheres. This method is completely unacceptable for some cars, because this method can only be used as temporary, for example, on the road, when you could not find the recommended data using a pressure gauge.
