Steering wheel vibration is a safety issue. It indicates a fault with tyres, wheels, brakes, or suspension, all of which affect your ability to control the car. Have it investigated as soon as possible.
At High Speed (60mph+)
Vibration that starts or worsens at motorway speed is most commonly caused by:
- Wheel imbalance (most common), Even a small imbalance in a wheel creates vibration that amplifies at speed. Fix: wheel balancing at a tyre centre (typically £5–10 per wheel).
- Uneven tyre wear, Tyres worn in patches or unevenly across the width cause vibration. May require tyre replacement.
- Damaged tyres, Internal tyre damage (belt separation) from a pothole or kerb strike. Often invisible externally. Fix: tyre replacement.
- Wheel alignment, Incorrect tracking causes uneven wear and vibration. Fix: wheel alignment (tracking).
When Braking
Shaking specifically when the brake pedal is pressed typically indicates:
- Warped or uneven brake discs, The most common cause. See our brake judder guide for detail.
- Worn brake pads, Uneven or glazed pads create uneven braking force.
- Sticking brake callipers, A calliper stuck partially on causes uneven braking and heat buildup.
At Low Speeds
Vibration at low speeds (under 30mph) that isn't present at higher speeds usually indicates suspension or steering wear:
- Worn control arm bushes or ball joints, Allow excess wheel movement, especially on uneven surfaces.
- Damaged tie rod ends or steering rack, Create looseness and vibration in the steering.
- Bent wheel or buckled alloy, Even minor alloy damage can cause low-speed vibration.
At All Speeds
Constant vibration regardless of speed or braking is often caused by:
- Severely unbalanced or damaged tyre
- Loose wheel nuts, Always check wheel nut torque after having wheels removed (service, tyre change). Retorque after 50 miles.
- Failing wheel bearing, Often accompanied by a humming or rumbling noise that changes with speed.
What to Do
- Reduce your speed, high-speed vibration is dangerous
- Check tyre pressures (low pressure causes uneven wear)
- Check for any obviously flat or damaged tyres
- Book an inspection with a mechanic, wheel balancing and alignment are quick and inexpensive if that's the cause; suspension and brake faults need professional diagnosis
