What to pay attention to
Vibration through the steering wheel, seat or pedals at a particular speed usually points to wheels, tyres, brakes or suspension components.
Why an inspection may still be needed
Wheel imbalance, tyre damage and worn steering or suspension parts can all produce similar vibration, so the wheels and steering are usually checked together.
A sensible next step
Note the speed range where it happens and whether braking changes it, then have the wheels, tyres and steering checked before driving at higher speed.
