What is the effect of under-inflated tyres?

Better traction in rainy conditions
Increased steering responsiveness
Higher fuel consumption and poorer handling
Improved braking distance

The correct answer is: Higher fuel consumption and poorer handling

Under-inflated tyres can significantly impact a vehicle's performance on the road. When tyres are not adequately inflated, they create more rolling resistance, which means the engine has to work harder to maintain speed. This leads to higher fuel consumption, as more energy is required to overcome the increased resistance. Additionally, under-inflated tyres can cause changes in handling characteristics, leading to poorer responsiveness when steering. This is particularly concerning during cornering or emergency situations where precise control is essential. The decrease in tyre pressure can also result in uneven wear patterns, further diminishing handling capabilities over time. Therefore, the presence of higher fuel consumption and poorer handling due to under-inflated tyres is a critical reason why maintaining proper tyre pressure is essential for safe driving and optimal vehicle performance.
