Quick answer
A car that shakes at certain speeds often has a tyre, wheel balance or wheel bearing issue. A car that shakes when braking often has a brake disc, pad, caliper or suspension issue. A car that vibrates at idle may have an engine mount, misfire or running fault.
Strong, sudden or worsening vibration should be checked quickly, especially if it comes with tyre damage, braking instability, pulling, knocking, grinding, humming or warning lights.
Match your symptom
Steering wheel shakes
Often tyre, wheel balance, brake, suspension or wheel bearing related.
Steering wheel shake guide →Car shakes at high speed
Often wheel balancing, tyre defects, bent wheels or wheel bearing noise.
High-speed shake guide →Car shakes when braking
Often brake discs, pads, calipers, suspension movement or hub play.
Braking vibration guide →Car vibrates at idle
Often engine mounts, misfire, rough idle, exhaust contact or running faults.
Idle vibration guide →Car shudders but drives fine
Can be mounts, misfire, clutch, idle control or engine running issue.
Idle shudder guide →Car judders when pulling away
Often clutch, engine mount, flywheel, throttle or drivetrain related.

Vibration that appears at 50–70 mph or motorway speeds is commonly linked to rotating parts: tyres, wheels, balancing, wheel bearings or drivetrain components.
- ✓Wheel imbalance: often felt through the steering wheel at certain speeds.
- ✓Tyre damage: bulges, flat spots, uneven wear or internal tyre faults can shake the car.
- ✓Bent wheel: pothole or kerb damage can cause vibration even with good tyres.
- ✓Wheel bearing: humming or droning that gets louder with speed may point to bearing wear.
- ✓Driveshaft or CV joint: vibration under load can sometimes come from drivetrain wear.
Helpful guides: car shakes at high speed, wheel bearing noise when speeding up and tyre pressure warning light reset.
Car shakes when braking
If the vibration appears mainly when pressing the brake pedal, the braking system is a strong suspect. The steering wheel may shake if the issue is at the front brakes.
- ✓Brake disc runout: uneven disc rotation can cause pulsing or vibration.
- ✓Uneven pad deposits: can feel like warped discs.
- ✓Sticking caliper: can overheat one brake and create vibration.
- ✓Worn suspension bushes: can allow movement under braking.
- ✓Wheel bearing or hub play: can make braking vibration worse.

Car vibrates at idle
If the car vibrates while stationary or idling, the cause is more likely to be engine-related than wheel-related. Engine mounts, misfires, rough idle, exhaust contact or idle control problems can all create vibration.
Engine mount wear
Can allow the engine to shake more than normal.
Misfire
Uneven combustion can make the engine shake at idle.
Exhaust contact
A loose mount or touching exhaust can transmit vibration into the cabin.

Car pulls to one side and vibrates
Pulling and vibration together can point to tyre pressure differences, uneven tyre wear, wheel alignment, sticking brakes, suspension wear or impact damage.
- ✓Check tyre pressures and visible tyre damage first.
- ✓Look for uneven tyre wear across the tread.
- ✓Consider wheel alignment after pothole or kerb impact.
- ✓Check whether one brake is overheating or dragging.
- ✓Inspect suspension joints, arms, bushes and track rod ends.
Helpful guides: car pulling to one side causes, car pulls left or right when driving and car pulls left after tracking.
What to check first
- 1Check tyre pressures on all four tyres.
- 2Inspect tyres for bulges, cuts, cracks, nails or uneven wear.
- 3Notice whether vibration happens at speed, when braking, at idle or when accelerating.
- 4Listen for humming, grinding, knocking or clicking noises.
- 5Think about recent pothole hits, kerb impacts or tyre changes.
- 6Check whether the car pulls left or right.
- 7Ask a garage to inspect tyres, wheels, brakes, suspension, steering and wheel bearings.
When car vibration is urgent
- !Vibration appears suddenly and strongly.
- !There is visible tyre bulge, damage or rapid pressure loss.
- !The car pulls sharply left or right.
- !There is grinding, knocking, scraping or loud humming.
- !The steering feels loose, heavy or unstable.
- !Brake pedal pulsates strongly or braking feels unsafe.
- !Warning lights appear with the vibration.
If the car feels unsafe, stop in a safe place and arrange inspection or recovery.
Can vibration cause MOT problems?
The vibration itself is a symptom, but the cause may fail an MOT. Unsafe tyres, worn suspension, loose steering parts, faulty brakes, excessive wheel bearing play or damaged wheels can all create MOT issues.

Frequently asked questions
Why is my car shaking while driving?
Common causes include wheel imbalance, tyre damage, bent wheels, worn suspension, brake problems, wheel bearing faults and alignment issues.
Why does my car shake at high speed?
High-speed shaking is often linked to wheel balancing, tyre defects, uneven tyre wear, bent wheels or wheel bearings.
Why does my car shake when braking?
Braking vibration often comes from brake discs, pads, calipers, wheel bearing play or suspension movement.
Why does my car vibrate at idle?
Idle vibration is commonly linked to engine mounts, misfires, rough idle, exhaust contact or running faults.
Can bad tyres make the car vibrate?
Yes. Bulges, flat spots, uneven tread, low pressure or internal tyre damage can all cause vibration.
Is it safe to drive with vibration?
Mild vibration may allow careful short driving, but sudden, severe or worsening vibration should be checked urgently.
