Which symptom could indicate tire failure in a heavy vehicle?

• A. Fish tailing wheels
• B. Quiet engine idle
• C. Smooth ride
• D. Reduced exhaust noise

Answer: (A)

Tire trouble on a heavy vehicle often shows up as instability and unpredictable handling. When tires lose grip or are underinflated or damaged, the vehicle’s rear end can start to push and swing from side to side. That swinging motion, where the back of the vehicle seems to wobble or fish tail, is a clear sign the tires are not holding traction properly. It’s a harbinger of potential loss of control, so recognize it quickly and respond by easing off the accelerator, braking gently if needed, and pulling over safely to inspect tires for proper inflation, tread wear, bulges, cuts, or other damage. The other signs listed don’t typically indicate tire failure. A quiet engine idle, a smooth ride, or reduced exhaust noise aren’t related to tire condition and wouldn’t alert you to tire problems.
