What sound indicates a tire blowout while driving?

A tire blowout is typically characterized by a sudden loss of air pressure in the tire, which leads to a loud and distinct thumping sound as the vehicle continues to roll. This thumping occurs because the flat tire is no longer able to support the weight of the vehicle, causing the sidewall to come into contact with the road surface intermittently. The rapid deflation can create a noticeable and alarming sound, which serves as a crucial indicator to the driver that immediate attention is needed to regain control of the vehicle, safely maneuver to the side of the road, and stop.

In contrast, the other sounds mentioned do not accurately represent a tire blowout. A sharp whistle is often associated with wind or aerodynamic issues, while a continuous humming noise typically relates to road or engine issues rather than a tire failure. A grinding noise often indicates a problem with the brakes or bearings, not the tires themselves. Understanding these distinct sounds can help drivers respond appropriately in emergency situations.
