Can You Still Drive with Tire Pressure Below 2.0?
2 Answers
Tire pressure below 2.0 bar should not be driven on. According to the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5 bar. A pressure of 2.0 bar is below the minimum standard value, which is abnormal. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and tendencies to veer, which are factors detrimental to driving safety; Increases movement in various parts of the tire, leading to abnormal heating due to excessive rolling; Reduces the functionality of the cords and rubber, causing delamination or cord breakage, excessive friction with the rim, and damage to the bead area, resulting in abnormal wear; Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening of the tire, and a drastic drop in strength. High-speed driving may lead to a blowout; Increases tire deformation, making the sidewalls prone to cracking, and generates flexing movements, leading to excessive heat, rubber aging, fatigue in the cord layers, cord breakage, and increased tire contact area, accelerating shoulder wear.
It's best not to drive if the tire pressure is below 2.0, as it's really dangerous. Low tire pressure causes excessive tire deformation, increases friction with the road surface, and can easily lead to overheating or even a blowout. Handling performance also deteriorates, braking distance increases, and the car is more prone to skidding when turning or on slippery roads. If road conditions are poor, accidents may occur. Standard tire pressure is generally between 2.2 and 2.5, and below 2.0 is already severely insufficient. I recommend stopping immediately to check, using a pressure gauge to measure each tire. If confirmed low, find the nearest gas station to inflate them. Driving long-term with low tire pressure also burns more fuel, accelerates tire wear, and the cost of replacing new tires is significant. Safety first—don't risk driving just to save a little time.
