Question

Difficulty: MediumTire Failure and Blowouts

When a commercial motor vehicle experiences a sudden tire blowout, a front steer-tire failure causes severe vibration and rear-end fishtailing, while a rear-tire failure creates a heavy steering pull toward the side of the damaged tire.

Answer: Answer

Answer

False
The statement is false because commercial vehicle safety principles state that a front steer-tire failure results in a severe steering pull toward the side of the blown tire. Conversely, a rear-tire blowout manifests primarily as vehicle vibration, thumping, and rear-axle fishtailing.

Step-by-Step Solution

1
Analyze the mechanical dynamics and physical symptoms of a front steer-tire failure.
A sudden deflation of a front tire increases rolling drag on that side, creating a powerful steering pull toward the failed tire.
Front tires directly interface with the steering linkage and determine directional stability.
2
Analyze the mechanical dynamics and physical symptoms of a rear drive or trailer tire failure.
A rear tire blowout generates distinct vehicle vibration, loud thumping sounds, and lateral swaying or fishtailing of the vehicle's rear end.
Rear tires provide tracking and load support rather than steering angle adjustment.
3
Compare the verified CDL emergency symptoms against the provided statement.
The statement inverts the diagnostic symptoms for front and rear tire failures.
Because the symptoms are swapped, the presented claim is completely false.
