Why is the tire pressure inconsistent in car tires?

[PresleyAnn]

Inconsistent tire pressure in car tires is related to the vehicle type, suspension tuning, and front-rear weight distribution. Here is some information about tire pressure values: Types: Tire pressure gauges are generally divided into three types: analog (dial) tire pressure gauges, digital tire pressure gauges, and alarm-type tire pressure gauges. Standards: There have been internationally established standards for appropriate car tire pressure. According to the international GBT2978-2008 standard, standard tires should have a pressure of 240-250 kPa; reinforced tires should have a pressure of 280-290 kPa; the maximum pressure for all types of tires should not exceed 350 kPa.

Inconsistent tire pressure is quite annoying, and I've encountered it several times over decades of driving. The main causes include natural air leakage, aging tire rubber or small holes, and slow leaks from loose valve cores. Temperature changes have a significant impact; in winter, the cold causes rapid pressure drops, while in summer, the pressure rises. After driving for a while, if you notice the steering wheel pulling to one side or a humming noise from the car, these are signs of uneven tire pressure, which can also increase fuel consumption and cause uneven wear. Regular checks are crucial. I use a tire pressure gauge to measure all four tires every month, keeping them around 2.3 to 2.5 bar. Developing this habit can prevent major issues. When I was younger, I didn't pay attention, and one tire wore out completely, nearly causing an accident.

There are quite a few reasons for inconsistent tire pressure. For example, a tire might be punctured by a nail without being noticed, or the valve cap might not be tightened properly, causing air leakage. Temperature changes can also play tricks—large temperature differences between day and night can cause tire pressure to fluctuate. If you notice your car being unstable while driving on the highway, it's a good idea to check the tire conditions. I bought a portable tire pressure gauge and keep it in the car, checking the pressure regularly and topping up air when needed. It's also a good practice to walk around the car before driving to see if any tire looks flat. Fixing minor leaks promptly can save you the expense of buying new tires unnecessarily.

I always feel that uneven tire pressure is dangerous, especially when driving with family. Possible reasons include air leakage issues or slow deflation caused by hitting debris while driving. Uneven tire pressure can reduce the car's grip, making it more prone to skidding in rainy weather. For safety, I perform a simple check every week, using a mobile app to measure pressure or visually comparing the shape of all four tires. If they're inconsistent, I promptly inflate them or send the car for repair, not delaying until safety is compromised.
