Is a tire pressure of 2.1 normal?
2 Answers
A tire pressure of 2.1 is not normal. The normal tire pressure should be between 2.3 and 2.5 bar. If the tire pressure is too high, the contact area between the tire and the ground will decrease, which can affect the tire's lifespan. If the tire pressure is too low, the tire will generate higher temperatures while driving, not only affecting the tire's normal use but also increasing the vehicle's fuel consumption. Car tires are one of the essential components of a vehicle, directly in contact with the road surface. They work together with the car's suspension to mitigate the impact during driving, ensuring good ride comfort and smooth driving. They also maintain good adhesion between the wheels and the road surface, thereby improving the vehicle's traction, braking, and off-road capability.
This tire pressure is on the low side and needs attention. I recommend checking the tire pressure label posted on the driver's side door frame first. For sedans, the standard range is usually between 2.3-2.5 bar, while SUVs may require 2.5-2.8 bar. A reading of 2.1 indicates potential risks. Insufficient tire pressure increases the risk of sidewall buckling deformation, which can easily lead to blowouts at high speeds. Last week, there was a case where a vehicle with 2.0 bar tire pressure had a tire come off the rim on the highway. Additionally, low pressure makes the steering wheel heavier and can increase fuel consumption by about 0.5 liters per 100 kilometers. The simplest solution is to visit a repair shop for a free check—they use professional tire pressure gauges for more accurate measurements and can also inspect for slow leaks caused by nails or other punctures. Remember to measure when the tires are cold for accurate readings.
