Can You Drive with Low Tire Pressure?
2 Answers
Driving at low speeds for short distances with insufficient tire pressure is acceptable, but never attempt long-distance high-speed driving. When tire pressure is low, high-speed driving can easily cause wave-like deformation, which significantly increases the risk of a tire blowout. Tire pressure can be about 10% higher than the recommended level, but it must never be lower. Excessively low tire pressure severely compromises driving safety. 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. Related question: Is 2.0 bar tire pressure normal? No. According to the international GBT2978-2008 standard, the normal range for standard tires is 2.4-2.5 bar. 2.0 bar is below the minimum recommended value, so it is abnormal. What is normal tire pressure in winter? In winter, adjust tire pressure to the vehicle's standard level, typically increasing it by about 0.2 bar. What is normal tire pressure in summer? Generally, use the lower limit of the standard tire pressure. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the pressure can be about 0.1 bar lower than standard to prevent blowouts from high temperatures.
When you see low tire pressure, I strongly advise against driving forcefully—it's quite dangerous. Having driven for decades, I've witnessed several accidents caused by severely low tire pressure leading to tire overheating and blowouts, especially on highways, where the consequences can be severe. Insufficient tire pressure increases the contact area, raises friction, generates excessive heat, and can easily damage the tire or even the wheel rim. Driving a short distance in an emergency is acceptable, but keep the speed below 30 km/h and head to a gas station or repair shop for inflation as soon as possible. I always carry a tire pressure gauge in my car and check the pressure regularly—don’t wait for the warning light to act. By the way, temperature changes affect tire pressure, so pay extra attention in summer and winter. Maintaining the manufacturer’s recommended pressure saves hassle, money, and ensures safety—don’t risk big losses for small neglect.
