How much proper car tire pressure should be higher for the front wheel


The original tire pressure standard for passenger cars is 2.3-2.5. The maximum should not exceed 3.0, and the minimum should not be less than 2.1, which falls within the normal range. Tyre standard air pressure (referred to as the standard tire pressure) can usually be found in the vehicle user manual, the label next to the cab door (near the B pillar), the drawer next to the vehicle's driver's seat, the fuel tank cover door, and so on. Different models have different weights and different tires. The front and rear wheels are generally not the same.

Excessive tire pressure can lead to a decrease in the contact surface between the tire and the ground, which can reduce fuel consumption, but it affects the braking force and increases the braking distance, which is detrimental to safe driving. Too low tire pressure will cause the tire sidewall to directly wear the ground. If it is too fast or too long, it will cause the sidewall to burst or even burst. If the tire pressure is too low, check the tire for leaks.

Tyre pressure is not 100% accurate and can be slightly higher but it must not be too low. If you are careful, winter and summer tire pressures are generally higher in winter than in summer, and the front wheels are a bit higher than the rear wheels. Such as the winter front 2.5, rear 2.4; summer front 2.4, rear 2.3.

In summer, due to the relatively hot weather, especially when driving at high speeds, when the speed reaches 100 to 120 yards, the tread temperature will reach 80°C, or even exceed 100°C, and the internal pressure will increase. So summer tire pressure is rather low.

Under normal circumstances, the owner should also adjust the tire pressure according to factors such as season, vehicle loading, environment, driving conditions, and tire condition.

In addition, the tire pressure of the spare tire should also be taken into consideration. Because the spare tire is not commonly used, the air pressure is preferably higher, so as to avoid losing the emergency effect due to low air pressure. Should generally be higher than 2.5. When used to adjust to the appropriate tire pressure, after inflation to high tire pressure 2.5-3.0.

For models without a tire pressure monitoring system, Xiaobian recommends that the owners prepare a barometer. The barometer can go to the auto shop to buy a better, mechanical type, electronic error will be a period of time. A barometer can take a long time.

Remember to measure air pressure at least once a month before the car starts. Because the tires are completely cooled after being left standing for 4 hours, the tire pressure measurement is most accurate when the tires are cold and empty.

When measuring the tire pressure, it is usually inflated first and then slowly put to the standard value. You can also slowly adjust the tire pressure in the process of using the car to find the most comfortable value.
