Why is maintaining correct air pressure in tyres crucial?

Maintaining correct air pressure in the tyres of a forklift is crucial for ensuring that the vehicle remains stable during operation. Stability is fundamental for safe lifting and lowering of loads, particularly when navigating uneven surfaces or while turning. Under-inflated tyres can lead to instability, increasing the risk of tip-overs and accidents, as they may not provide adequate support and grip. Over-inflated tyres can also compromise stability, leading to a harsh ride and reduced traction.

While other factors such as speed, noise, and visibility can be affected by tyre pressure, they do not directly relate to the core operational performance and safety of the forklift in the same way that stability does. For instance, although proper tyre pressure can help with traction and performance, the primary reason for maintaining optimal air pressure hinges on how it affects the forklift's balance and safety when lifting and transporting loads.
