Does the tire run 4 times a year? Is it normal?
First of all, how much gas should I fill the tires? This should be treated according to specific circumstances. More than two pounds (1 pounds = 0.4536 kilograms) of gas, although it will reduce tire friction, but also save a little oil, but the high hardness of the tires will also lead to uneven running of the car. But if the car is carrying too much cargo or passengers, a little more gas is good because it can offset additional pressure. General automotive manual provides reference tire pressure, most cars and small trucks recommended inflation range is 2732psi (pounds per square inch), for large trucks and buses, the recommended value than the average car high inflation 58psi, in order to adapt to the same weight larger. Although the recommended volume of inflation is not necessarily the best in all cases, it is, on the whole, the most scientific.
Normally, all tyres leak a little, and some even leak 1 pounds for two months, but if they exceed this amount, check that there is a leak. It's better to check the tire pressure once a month, especially before long distance travel. In addition, although the recommended volume of the front and rear tires may not be the same, the pressure on the left and right tires should be consistent. Otherwise, the gap between two and over will lead to the deviation of the steering wheel.
The manual recommended car tire pressure is generally aimed at cooling the tire, the said check tire pressure should be carried out in the morning before driving, if traveling some distance in the car immediately after the check, because the temperature of the tire so that tire air expands, reading will be much higher than the normal state. Check the tire pressure by using a standard scale when checking. Don't use the built-in meter in the gas station compressor, which is very inaccurate, and do not try to make a judgment based on visual inspection, because that sometimes results in an error of about 10 pounds. When inflated, check the meter from time to time until the recommended charging value is not more than two pounds. Be careful not to exceed the maximum inflated value on the tire under any circumstances, or the tire will burst. Insufficient inflation can also cause tire wear. When the tire is inflated, for example, the pressure is only 12 to 18psi, the sidewall of the tire will bear too much pressure, which can produce a lot of heat and cause damage to the tires.
