What symptom indicates a tire bows out at highway speed?

• A. A vibrating feeling
• B. A sudden jerk
• C. A loud screech
• D. A rough ride

Answer: (A)

A vibrating feeling indicates a tire that bows out because the tire isn’t perfectly round anymore. When a tire has a deformity or belt separation, its contact patch with the road changes as it spins. That irregular contact creates an imbalance, which you feel as vibration, especially at higher speeds where the forces are larger and there’s less time for the tire to smooth out each rotation. A sudden jerk would point to a sudden loss of traction or a steering or driveline issue rather than a persistent tire shape problem. A loud screech usually comes from tire slip or braking noise, not from a tire that’s bowed outward. A rough ride can be caused by many things, including road conditions or suspension issues, but it doesn’t specifically signal a bowed tire like a vibration does. So the persistent vibration at highway speed is the best clue that a tire may be bowing out.
