What Causes Steering Wheel Vibration When Speed Exceeds 100 km/h?
2 Answers
Steering wheel vibration when speed exceeds 100 km/h is caused by wheel imbalance, requiring a wheel balancing service. Wheel balancing ensures tires maintain relative stability during high-speed rotation for normal vehicle operation. After tire repairs, uneven weight distribution occurs, necessitating balancing weights to restore stability. Symptoms of imbalanced tires include severe bumpiness, abnormal vibrations, steering pull, irregular handling, increased fuel consumption, and uneven tire wear. Whenever these symptoms appear or after installing new tires, immediate wheel balancing is essential to ensure proper vehicle performance.
Having driven for over a decade, I've found that steering wheel vibration at speeds above 100 km/h is most commonly caused by tire imbalance or uneven tire pressure. When tires are worn or wheel balancing is off, uneven forces at high speeds lead to shaking. I once encountered this issue during a long-distance trip—turned out the old tires had deformed, and replacing them fixed the problem. Additionally, bent rims or aging suspension components like leaking shock absorbers can also contribute to the shaking. I recommend regular wheel alignments and tire checks instead of waiting until the shaking starts—safe driving brings peace of mind. Pay attention to unusual sounds and sensations while driving daily for early prevention. Also, inspect tire conditions during car washes to spot and address issues early, saving both hassle and money.
