What is the minimum tire pressure below which driving is not recommended?

[WestonDella]

The tire pressure monitoring system will issue an alert when the pressure falls below 1.5 bar, so this value is also a general recommendation for tires without pressure sensors not to go below this level. The normal tire pressure for most passenger cars typically ranges between 2.1 and 2.8 bar. Driving with excessively low tire pressure can cause the tires to overheat, soften, and potentially lead to a blowout. Tire pressure also varies with the seasons. In winter, it's advisable to slightly increase the pressure by about 0.2 bar above the standard tire pressure for your vehicle. In summer, when parking outdoors, the pressure can generally be about 0.1 bar lower than the standard to prevent blowouts due to high temperatures. For new tires, the pressure can be set about 0.2 bar higher than the standard, while for older tires, it's appropriate to slightly lower the pressure according to the standard.

As a seasoned long-distance driver, I believe you should stop driving when the tire pressure drops 20% below the recommended value. For example, if the vehicle label indicates a recommended pressure of 30 psi or 220 kPa, you must pull over when it falls below 24 psi or 180 kPa. Low tire pressure causes excessive sidewall flexing, and prolonged high-speed driving generates dangerous heat buildup. I once experienced a blowout at 20 psi on the highway—terrifying and nearly caused a loss of control. Since then, I’ve been extra cautious with TPMS warnings, stopping immediately to check when the light comes on. My advice: always measure tire pressure when cold and maintain the recommended level—both over- and underinflation are risky, but low pressure is far more dangerous. Spend a minute checking tire pressure before trips—it’s a small effort that could save your life. If you hit the critical point, don’t push it—call for help or refill the tires.

I'm quite concerned about fuel efficiency in daily car usage. Whether you can drive with low tire pressure depends on how much it's below the recommended value. Generally, if the monitoring shows it's 15%-20% below, you shouldn't drive. For example, if the recommended pressure is 32 psi, dropping below 26 psi becomes a serious issue because the increased tire contact area leads to higher friction, soaring fuel consumption, and potential tire blowout risks. Once I neglected this and drove with 22 psi tire pressure in the city, resulting in a 20% increase in fuel consumption. The end-of-month refueling was painfully expensive, and the tires wore out faster too. I believe this isn't just a safety issue but also an economic one – replacing a tire costs hundreds, so it's better to conduct regular checks to ensure the pressure stays within the ideal range. Checking tire pressure monthly is simple and efficient, making the car more stable and easier to drive. If the tire pressure warning light comes on, stop immediately, use a tire pressure gauge to confirm, and then decide whether to inflate. Don't drive blindly to avoid making the situation worse.

I'm quite curious about the little tech features in cars. The Tire Pressure Monitoring System (TPMS) actually sets a safety threshold - you should stop driving when the pressure falls 20%-25% below the recommended value. For example, if the standard recommendation is 35 psi, the sensor will trigger a warning light when it detects pressure below 28 psi, indicating you shouldn't continue driving. This is because it increases the risk of tire deformation and internal steel belt fractures. I've added an external display to monitor real-time data, so I can address any anomalies immediately and maintain proper tire pressure for safer driving. This technological design exists precisely to prevent potential hazards - never ignore its warnings. It's a convenient and practical solution that addresses major driving concerns.

When I first started driving, I was terrified of low tire pressure. My instructor taught me that if the monitoring shows it's below 80% of the recommended level, you should stop. For example, if the recommended pressure is 30 psi and it drops to 24 psi, the tire is almost flat, making the car feel floaty and prone to skidding during turns. Once, my tire pressure warning light came on, and I panicked, pulling over to find it was at 20 psi. I immediately called a tow truck. Now, I've developed the habit of checking tire pressure every time I refuel to ensure it's within the recommended range. New drivers, in particular, should pay special attention to low tire pressure—it's a major hazard. Don't follow others who insist on driving with low pressure; safety should always come first.
