Why does the steering wheel shake only at high speeds?

The reasons why the steering wheel shakes only at high speeds are: 1. Tire issues; 2. Problems with the car's chassis; 3. Issues with vehicle resonance; 4. Brake disc problems. The shaking of the steering wheel is a sign of poor wheel balance. When the owner notices the above problems, they should first check whether the tire pressure of the front and rear wheels is normal. The steering wheel is a wheel-like device that controls the direction of travel, and its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. While driving, the steering wheel should be turned left and right to check whether it is flexible, whether there is a lack of return force, and whether the vehicle will deviate when the steering wheel is released.
As a seasoned driver with decades of experience, I've seen this issue many times. The main causes of steering wheel shaking at high speeds are usually tire imbalance, where each wheel rotates unevenly, causing more vibration the faster you go; warped brake discs can also cause shaking, especially when braking; another reason could be wheel rim deformation, where minor damage from impacts isn't noticeable at low speeds but becomes apparent at high speeds. Additionally, loose or worn suspension components can exacerbate the shaking. Resonance is a common cause, where parts vibrate more intensely at certain speeds due to matching frequencies. I strongly recommend getting a wheel balance test and four-wheel alignment done at a shop as soon as possible—fix it early for peace of mind before it leads to bigger problems. Regularly avoid potholes while driving and check tire wear periodically to prevent potential hazards.
Once while driving on the highway, my steering wheel suddenly started shaking violently, which was quite frightening. After getting it repaired, I found out it was caused by warped brake discs. At low speeds, the vibration is minimal due to the slower pace, but it intensifies and causes severe shaking at high speeds. Misaligned wheels or uneven wear can also contribute to this issue; incorrect tire pressure plays a role too, as having one tire over or under-inflated can make the car unstable. Additionally, an unbalanced driveshaft can transmit vibrations to the steering wheel when rotating at high speeds. My advice to drivers experiencing this is not to push through it—slow down, find a safe place to pull over, do a quick check of tire pressure and wheel condition, then head to a professional shop for a thorough diagnosis. Only continue driving once safety is confirmed.
