What causes severe shaking when driving at 70 mph?

[VanDamian]

Severe shaking when driving at 70 mph is generally caused by improper wheel balancing or four-wheel alignment. It is recommended to take the vehicle to a 4S shop for inspection and repair. Other possible causes: Excessive tire pressure: If the tire pressure is too high, the vehicle will bounce more when driving on bumpy roads, and the body is more likely to shake at high speeds, increasing the risk of a tire blowout. Generally, the recommended tire pressure is around 2.5 bar. Severe tire wear: If the tires are severely worn and the tread is uneven, it can also cause the car to shake at high speeds. In such cases, the tires should be repaired or replaced promptly.
