Is a tire pressure of 200 kPa normal?
2 Answers
A tire pressure of 200 kPa is not normal. The normal tire pressure range is between 230 to 250 kPa. Hazards of low tire pressure: 1. Increased friction coefficient with the road surface; 2. Causes the steering wheel to feel heavy and makes the vehicle prone to deviation, among other factors detrimental to driving safety; 3. Increases the movement of various parts of the tire, leading to excessive rolling and abnormal heating of the tire; 4. Reduces the functionality of the cord and rubber, causing delamination or cord breakage, and excessive friction between the tire and rim, resulting in damage to the bead area and abnormal wear; 5. Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening of the tire, a rapid decrease in strength, which may lead to a tire blowout when the vehicle is driven at high speeds.
As an ordinary driver with years of experience, I think 200kpa tire pressure is slightly on the low side. The normal tire pressure for passenger cars is generally around 210 to 250kpa, equivalent to 2.1 to 2.5 bar. 200kpa equals 2.0 bar, which is almost the minimum value of the normal range. When my car's tire pressure was too low, I felt the car became heavier to drive, and fuel consumption increased noticeably. Once, I neglected to check the tire pressure, and the tires overheated badly on the highway, almost causing an accident. I suggest you immediately find a pressure gauge to re-measure, preferably when the vehicle is cold for more accurate results. Adjusting to 220 or 230kpa should be more comfortable and safer. Additionally, unstable tire pressure can affect driving smoothness and increase braking distance in rainy weather, so don't overlook daily maintenance. Check the recommended value label on the door edge—it's the most reliable reference. Overall, addressing this small issue promptly will save you both peace of mind and money.
