Why is maintaining proper tire inflation important for Class B vehicles?

• A. It helps maintain fuel efficiency, safe handling, and prevents excessive tire wear.
• B. It has no impact on safety
• C. It only matters for new tires
• D. It should be checked only during a service

Answer: (A)

Keeping tires inflated to the recommended pressure is essential because it ensures the tire’s contact patch with the road is correct, which gives predictable handling, braking, and traction. When tires are underinflated, they deform more as they roll, generate extra heat, increase rolling resistance, and wear the tread on the outer edges; the added heat also raises the risk of a blowout, especially under heavy loads. Overinflated tires ride on a smaller, stiffer patch, reducing traction and causing center tread wear and a harsher ride. For Class B vehicles, which regularly carry heavy loads and passengers, these effects are magnified: improper inflation can compromise steering and braking, raise fuel consumption, and shorten tire life, increasing the possibility of tire failure on the road. Regularly check tires when cold and inflate to the vehicle’s recommended pressure from the door placard or owner’s manual, using a reliable gauge and inspecting for uneven wear to stay safe and efficient.
