How Long Can You Drive with Tire Pressure Showing 190?
2 Answers
Tire pressure showing 190kpa should not be driven on, as 190kpa indicates that the tire pressure is too low. Continuing to drive under such conditions can lead to certain consequences. Hazards of Low Tire Pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Heavier steering wheel and a tendency to veer off course, which are factors detrimental to driving safety; Increased movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduced functionality of the cord and rubber, leading to delamination or cord breakage, excessive friction with the rim causing damage to the bead area, and abnormal wear; Exponentially increased friction between the tire and the ground, rapid rise in tire temperature, softening of the tire, and a sharp decrease in strength. High-speed driving under such conditions may result in a tire blowout; Increased deformation of the tire body, making the sidewalls prone to cracking, along with flexing movements that cause excessive heat, accelerating rubber aging, fatigue in the cord layers, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
A tire pressure of 190 is indeed quite low, as the normal range is usually around 220. You shouldn't drive for too long in this condition. I remember one time when my tire got punctured and the pressure dropped to about this level—I immediately found a place to pull over and check it. Driving for extended periods with low pressure causes excessive flexing of the tire sidewalls, and when temperatures rise, it significantly increases the risk of a blowout, which is extremely dangerous. In this situation, it's best not to drive more than 10 kilometers and keep your speed below 50 mph. Try to reach the nearest repair shop for inflation as soon as possible. If you notice the tire visibly flat or hear a hissing sound indicating air leakage, it's safer to pull over immediately and call for roadside assistance. Keeping a portable air pump in the trunk is highly practical—it can be a lifesaver in emergencies.
