Practice question

What is the result of improper tire inflation for commercial vehicles?

  1. Improved fuel efficiency
  2. Enhanced traction control
  3. Increased risk of tire blowouts
  4. Better overall vehicle performance

Answer: C — Increased risk of tire blowouts

Improper tire inflation in commercial vehicles leads to an increased risk of tire blowouts. When tires are either under-inflated or over-inflated, they do not perform optimally, which can cause excessive heat buildup, uneven wear, and structural damage to the tire. Under-inflation can lead to the tire flexing too much, generating heat that can result in a blowout. Over-inflation, on the other hand, can cause the tire to be more rigid, making it susceptible to damage from road hazards. Maintaining proper tire inflation is crucial for safety, as it helps ensure that the tires grip the road effectively and distribute the weight of the vehicle evenly. This ultimately contributes to the vehicle's overall reliability and performance on the road.
