What Causes High-Speed Vehicle Vibration?

[SavannahFitz]

High-speed vehicle vibration can be attributed to the following reasons: 1. Uneven brake disc surfaces with excessive radial runout, caused by uneven braking force or misaligned brake pad positions; 2. Excessive tire pressure, leading to noticeable vibration when driving over uneven road surfaces at high speeds; 3. Severe tire wear resulting in significant imbalance; 4. Under high-speed and high-load conditions, fuel quality and ignition determine engine performance—if either is abnormal, it can cause engine weakness and vibration. Solutions for high-speed vehicle vibration include: 1. Checking tire pressure before high-speed driving. It is recommended to avoid excessive tire pressure in summer, with a reduction of 0.1 to 0.2 bar, while slightly increasing tire pressure by 0.1 to 0.2 bar in winter; 2. For issues like vehicle pulling or abnormal tire wear, a four-wheel alignment can be performed. Regular four-wheel alignments help check whether the vehicle's mechanisms are functioning properly.
