Why does my car vibrate at speed?
A vibration that appears or worsens at a certain speed — commonly 60–70mph — is most often caused by unbalanced wheels or tyres. This is a cheap fix: wheel balancing costs £30–60 for all four wheels. If balancing does not fix it, worn tyres (flat spots or internal damage), wheel bearing failure, or worn suspension components may be the cause.
Likely causes
Unbalanced wheels
Most common cause — weights fall off or the balance changes. Cheap to fix.
Worn or damaged tyres
Flat spots from extended parking, internal delamination, or severely worn tread
Wheel bearing failure
Generates vibration and humming that changes when you steer slightly — worsens over time
Worn brake discs (warped)
Vibration specifically when braking, often felt through the brake pedal
Worn CV joint or driveshaft
Can cause vibration under acceleration or at certain speeds
