What could be a consequence of under-inflated tires on a truck?

• A. Better fuel efficiency
• B. Increased risk of blowouts
• C. Enhanced stability
• D. Decreased wear on suspension

Answer: (B)

Under-inflated tires on a truck lead to an increased risk of blowouts primarily due to the excessive heat generated from the increased flexing of the tire sidewalls. When tires are not inflated to their recommended pressure, they cannot support the weight of the vehicle effectively. This can cause the tires to overheat as they flex more than they should during operation. Overheating can weaken the tire structure and may eventually lead to a sudden failure, or a blowout, placing the driver at significant risk while also endangering others on the road.

Additionally, under-inflated tires may negatively impact other aspects of vehicle performance, such as fuel efficiency and stability, whereas having properly inflated tires is crucial for even wear on the suspension components.
