What is the reason for the buzzing sound at 120 km/h?
1 Answers
The reasons for the buzzing sound at 120 km/h are as follows: 1. Excessive tire pressure: When using the car, the tire pressure should be adjusted within the standard range (usually 2.3bar-2.5bar). If the tire pressure is too high, it will cause severe wear on the tire tread, reduce the tire's shock absorption performance, and make the tire noise more noticeable. 2. Abnormal tire wear: The tire tread comes into contact and friction with the ground. If the tread wears unevenly and has bumps, it will produce a buzzing sound. 3. Damaged wheel hub bearing: Worn wheel hub bearings will cause a buzzing sound due to 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 normal use.
