What Causes the Humming Noise When Driving at High Speeds?

1 Answers

The main reasons for the humming noise when driving at high speeds are as follows: 1. Abnormal noise caused by excessive tire pressure: During daily use, tire pressure should be adjusted within the standard range (generally 2.3bar-2.5bar). Excessive tire pressure can cause severe wear on the tire crown, reducing the tire's shock absorption and buffering performance, and significantly increasing tire noise. 2. Abnormal noise caused by uneven tire wear: The tire crown contacts and rubs against the ground. If the tire crown wears unevenly with bumps, it will produce a humming noise. 3. Abnormal noise due to damaged wheel hub bearings: Worn wheel hub bearings will generate a humming noise, mainly caused by long-term use leading to wear and looseness. To protect the wheel hub bearings, avoid violent impacts on the wheels and prolonged driving through water during daily use.
