Car tire pressure at 150 kPa is not suitable for driving. According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: Should not exceed 3.5 bar. Tire pressure reset method: First, turn on the ignition, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Generally, an alarm will trigger if the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, it can also cause the tire pressure warning light to turn on. For sensor damage, the only solution is to replace it with a new component.

Last time I noticed the tire pressure showed 150 kPa, it was almost a disaster - absolutely undrivable! That pressure is way too low. The standard value is usually around 220 kPa. Such a big difference causes severe tire deformation, making steering sluggish and increasing fuel consumption. What worried me most was that if driven on highways, the tires would overheat too quickly and risk a blowout - that's no joking matter. I barely managed to drive to a gas station that time, with the car wobbling dangerously along the way, nearly losing control. Fortunately, inflating to 240 kPa immediately solved the problem. Remember: low tire pressure isn't just dangerous, it damages your vehicle too. If you notice any abnormality, get it checked at a service point immediately - never sacrifice safety for the sake of saving time.

From my decade-plus experience of driving, I can say that driving with tire pressure as low as 150 kPa is barely possible for a short distance, but you should absolutely avoid going far. I remember one winter morning when I started the car and the dashboard showed a tire pressure of 150. Thinking it was fine, I drove to the supermarket, but after just two kilometers, the car felt sluggish, and fuel consumption skyrocketed. Later, a mechanic told me that 150 kPa is way below the standard 220 kPa, causing faster wear on the tire sidewalls and significantly increasing the risk of a blowout over time. While you might move the car in an emergency, you should inflate the tires to around 230 kPa as soon as possible and check for cracks or leaks at the valve stem. Safety should always come first.

I think a tire pressure of 150 kPa is really not acceptable, the normal value should be around 220 kPa. Because insufficient tire pressure increases the tire's contact area with the road, leading to higher rolling resistance, which not only consumes more fuel but also accelerates tire aging. More seriously, on bumpy roads, it can easily cause damage to the tire sidewall, increasing the risk of a blowout. I usually make it a habit to check with a pressure gauge before driving, and if it's below 180 kPa, I inflate the tires immediately—never wait until it drops to 150 kPa to panic. Simply put, maintaining proper tire pressure is a habit that saves money and ensures safety.

From a cost-saving perspective, driving with a tire pressure of 150 kPa feels like a huge waste! Low tire pressure significantly increases fuel consumption because the deformed tires create more resistance – you might burn an extra half liter of fuel for every 10 kilometers driven. Over time, it also drastically shortens tire lifespan. A new tire normally lasts four to five years, but if you keep driving with underinflated tires, you'll need replacements in just two to three years, costing at least several hundred bucks per tire. My advice: visit a repair shop to inflate them to 220 kPa and check periodically. This ensures both safety and wallet-friendliness.

If you find the tire pressure is only 150 kPa, I recommend not starting the car or pulling over immediately. First, check if the unit on the tire pressure gauge is kPa. If the dashboard indicates it's within the normal range, then it's fine. However, 150 kPa is definitely too low. The safe approach is to find an air pump and inflate it to around 220 kPa, or use your to locate nearby repair shops. If you absolutely must move the car, drive slowly for a short distance but avoid highways, while monitoring steering wheel vibrations and fuel consumption changes to prevent sudden hazards.
