Why Does the Steering Wheel Shake on the Highway?

[OKatherine]

Here are the reasons for steering wheel shaking on the highway: 1. Poor tire dynamic balance: During driving, if a tire experiences a strong local impact, it may cause the balance weights to fall off or become damaged, affecting the tire's dynamic balance. 2. Significant differences in tire pressure among the four tires: When there is a large difference in tire pressure among the four tires, especially between the left and right wheels, the car will experience noticeable bumps and steering wheel shaking at high speeds. 3. Poor wheel alignment: When the wheel alignment angles deviate significantly, the car may exhibit body drift and shaking at high speeds, as well as uneven tire wear, accelerating tire wear and shortening tire lifespan.
