What is the correct pressure for properly inflated tires on a school bus?

• A. 80 psi
• B. 105 psi
• C. 90 psi
• D. 100 psi

Answer: (B)

The correct pressure for properly inflated tires on a school bus is 105 psi. Maintaining the correct tire pressure is crucial for several reasons. Proper inflation ensures optimal contact between the tires and the road surface, which enhances safety by providing better traction and handling. Additionally, correctly inflated tires help with fuel efficiency, as under-inflated tires can increase rolling resistance and lead to higher fuel consumption. Over-inflation, on the other hand, can cause uneven wear and increase the risk of a blowout. Therefore, 105 psi is typically the recommended pressure for school bus tires, aligning with manufacturer specifications to maximize performance and safety on the road.
