What consequence might occur due to too much weight on a steering axle?

Answer: C — Hard steering and tire damage

Too much weight on a steering axle can lead to hard steering and tire damage because excess weight can overload the axle and affect the vehicle's handling. When the steering axle is overloaded, it can make turning more difficult, causing the driver to exert more force on the steering wheel, which may lead to fatigue over time. Furthermore, excessive weight can lead to uneven wear and tear on the tires, increasing the risk of blowouts or reduced traction. This scenario demonstrates how proper weight distribution is vital for safe vehicle operation, as it not only affects maneuverability but also the lifespan of the tires and overall vehicle safety. The other options do not accurately reflect the consequences of overloading the steering axle; for example, improved handling and better fuel efficiency would be counterproductive outcomes of such a weight issue.
