Red Seal Heavy Duty Equipment Technician Practice Exam

What happens due to improper tire inflation on heavy equipment?

1. Increased fuel efficiency

2. Decreased tire wear

3. Increased tire wear and potential safety hazards

4. Improved ride quality

The correct answer is: Increased tire wear and potential safety hazards

Improper tire inflation has significant negative impacts on heavy equipment, primarily leading to increased tire wear and potential safety hazards. When tires are under-inflated, they flex more than they should, generating excessive heat and causing the rubber to wear quickly. This can lead to sidewall bulging and increased susceptibility to punctures, which can compromise the structural integrity of the tire. On the other hand, over-inflation can result in a harsher ride and reduced contact with the ground, which can cause uneven wear patterns and diminish traction. Both scenarios can lead to premature tire failures, affecting not only the vehicle's performance but also the safety of the operator and others on the job site. Additionally, improper tire inflation can result in decreased fuel efficiency because the engine has to work harder to compensate for poor traction and handling characteristics. Therefore, keeping tires properly inflated is crucial for extending tire life, ensuring safety, and improving overall equipment efficiency. This understanding highlights the importance of regular tire maintenance and checks in the operation of heavy equipment.
