What Causes Body Vibration at High Speeds?

[SebastianLee]

High-speed body vibration can be caused by a variety of reasons. The most common causes are as follows: 1. Tire Issues: Problems with tires mainly involve abnormal tire pressure or severe tire wear. Excessive or insufficient tire pressure, as well as significant differences in tire pressure among the four tires, can lead to body vibration at high speeds. For example: Under normal conditions, the front tire pressure is usually around 2.3 bar, and the rear tire pressure is about 2.4 bar. If the right front tire pressure is 2.0 bar and the left rear tire pressure is 2.2 bar, the difference in pressure will cause inconsistent energy absorption and shock absorption capabilities of the tires, resulting in body vibration at high speeds. 2. The Vehicle Requires Wheel Balancing or Four-Wheel Alignment: It's important to note that wheel balancing and four-wheel alignment are two different things.
