What does proper tire inflation contribute to in a commercial vehicle?

Proper tire inflation is crucial in a commercial vehicle as it significantly influences both braking and handling. When tires are correctly inflated, the surface area that contacts the road is optimized, which provides better traction. This improved traction enhances the vehicle's ability to stop effectively, reducing the stopping distance and increasing overall safety during braking maneuvers.

Additionally, appropriate tire pressure ensures even tire wear, which is essential for maintaining stability and responsive handling. When tires are properly inflated, they can better absorb shocks from road irregularities, leading to a smoother and more controlled driving experience. In contrast, under-inflated or over-inflated tires can compromise a vehicle's handling characteristics and braking performance, making it more challenging to control the vehicle, especially during adverse conditions.

While tire inflation does indeed affect fuel efficiency and can influence other aspects of driving, such as comfort and noise levels, the most critical factors explicitly impacted by proper tire inflation are braking and handling, ensuring that the vehicle performs safely and effectively on the road.
