Tire balance
A missing wheel weight creates a vibration that peaks at certain speeds. Rebalancing is quick and inexpensive.
Other common causes
- Bent rim from a pothole
- Tire belt separation (look for a bulge)
- Worn tie rods or ball joints
- Damaged CV axle
- Loose lug nuts — dangerous, check immediately
Where you feel it matters
In the steering wheel: front wheels. In the seat or floor: rear wheels or driveline.
