Can You Continue Driving When the Tire Pressure is Low on the Highway?
1 Answers
When the tire pressure is shown to be low on the highway, you should not continue driving. You need to find an exit or service area to inflate and check the tire pressure, and perform tire repairs if necessary. Reference standards for adjusting tire pressure: According to the international GBT2978-2008 standard, the standard tire pressure is approximately 2.4-2.5bar for standard tires and 2.8-2.9bar for reinforced tires. On roads with significant bumps, it is appropriate to reduce the tire pressure by 0.1-0.2bar below the standard tire pressure. For long-distance highway driving, the tire pressure should not be too low; it is advisable to increase the tire pressure by about 0.2bar above the lower limit of the standard tire pressure. Effects of low tire pressure: It can cause the friction between the tire and the ground to multiply, leading to a sharp rise in tire temperature, softening of the tire, and a significant drop in strength. When driving at high speeds, this may result in a tire blowout. It can also increase tire deformation, making the sidewalls prone to cracking and generating flexing movements, which leads to excessive heat, accelerates rubber aging, causes fatigue in the cord layers, and may break the cords. Additionally, it increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
