What Are the Reasons for a Slightly Unbalanced Car and the Feeling of Low Tire Pressure in the Rear Wheels?
2 Answers
If the car is slightly unbalanced and the rear wheels feel like they have low pressure or are being pressed, it might be due to a small puncture in the tire. Below are some car tire maintenance methods: 1. Monthly Tire Pressure Check: Both underinflation and overinflation can lead to abnormal tire wear, shorten tire lifespan, increase fuel consumption, and even raise the risk of a blowout. Experts recommend checking tire pressure once a month to ensure it is at the correct level. Tire pressure should be checked when the tires are cold. You can use a tire pressure gauge or a Tire Pressure Monitoring System (TPMS) to check the pressure. The vehicle's manual will list the standard tire pressure for various load conditions. This information is also usually found on a label near the driver's door. The standard tire pressure is typically around 2.2~2.6 bar. Overinflation can increase tire wear and the risk of a blowout, while underinflation can lead to higher fuel consumption and a bumpier ride. Generally, tire pressure can be slightly lower in summer and slightly higher in winter. 2. Always Pay Attention to Tire Wear Indicators: The wear indicators are located in the main tread grooves and appear as small, trapezoidal rubber blocks. When the tread wears down to the level of these indicators, the tire must be replaced. During the rainy season, to prevent the car from skidding on wet roads, the tread depth should be kept above 3mm.
When driving, if you feel the car is a bit bumpy and uneven, especially as if the rear tires are flat, it's most likely due to insufficient tire pressure. I've experienced a similar situation before, that time on the highway, the car was swaying badly from side to side, so I quickly slowed down and pulled over. Upon checking the rear tire pressure, it was indeed much lower than the normal value, probably due to a slow leak or a puncture from a nail. Too low pressure can cause the tire to deform, leading to imbalance while rolling, making the whole car feel unstable. It's recommended that you immediately find a safe place to stop, use a tire pressure gauge to check the pressure. The normal tire pressure is generally around 2.5 bar. If it's too low, inflate it or go to a repair shop to fix the tire. Pay more attention to the condition of your tires in daily use and check the pressure every two weeks to avoid such trouble.
