Is a tire pressure of 1.4 bar indicating a puncture?

[Johnson]

A tire pressure of 1.4 bar might be caused by a nail puncture or other reasons leading to air leakage. It is recommended to first check if there is a nail in the tire, reinflate it, and observe whether it loses air quickly. If the air loss is rapid and no nail is found, visit a service station when possible to diagnose the issue. Risks of overinflated or underinflated tires: For tires, the pressure should neither be too high nor too low. Overinflation reduces the contact area between the tire and the ground, leading to poor grip, which affects the vehicle's handling and driving stability. Underinflation can cause wave-like deformation during high-speed driving, reducing the tire's lifespan and increasing the risk of a blowout. Standard tire pressure guidelines: According to the international GBT2978-2008 standard, the recommended tire pressures 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.

I've been driving trucks for a long time and know quite a bit about tire pressure. Normal tire pressure usually ranges between 2.2 to 2.5 bar, so your 1.4 bar is definitely too low – it feels like the tire is leaking. If there's a puncture, you can usually spot a nail or hole, or hear unusual noises from the tire. I suggest you stop driving immediately, pull over somewhere safe, and try spraying soapy water on the tire surface. Bubbles will indicate the leak point. Even if you don't have professional tools, temporarily inflating the tire to drive short distances is risky. Long-term low-pressure driving can deform the tire, cause excessive wear, and increase the risk of a blowout. Safety first – don't delay, check it right away or find a repair shop to fix the puncture.

As someone who frequently drives long distances, I've experienced quite a few tire pressure changes. 1.4 bar sounds alarming - normal car tire pressure is usually over 2.0, so this low reading is likely due to a puncture, like from a nail. Temperature drops might lower pressure slightly, but never this drastically to 1.4. If your car feels wobbly or unstable while driving, it's definitely an air leak. Quickly inspect the tire surface for foreign objects or listen for hissing sounds to locate the leak. Remember, driving with low pressure wastes fuel and is dangerous, especially on highways. Best to visit a tire shop immediately for inspection - don't delay.

I see your tire pressure is only 1.4 bar, which is definitely too low. The normal level should be above 2.2. It might be caused by a puncture and air leakage, or possibly issues with the valve or rim. In any case, you need to check it immediately. Driving with low pressure is very dangerous—tires can overheat and burst, leading to loss of control and skidding, especially when braking on curves. Pull over to a safe spot right away and inspect the tire's appearance or perform a simple inflation test to locate the leak. If you don’t have the tools, don’t risk driving—call for roadside assistance or a tow truck to get it fixed. Safety is more important than saving money. Ignoring such a small issue can lead to major hazards.
