Why is keeping air-filled tyres at correct operating pressure important?

• A. To reduce noise
• B. To increase load capacity
• C. To maintain stability and safety of the forklift
• D. To improve fuel efficiency

Answer: (C)

Keeping air-filled tyres at the correct operating pressure ensures the forklift sits on a stable, predictable base. The tyre footprint and stiffness depend on pressure, so with the right pressure the load is supported evenly, steering remains responsive, and braking and cornering stay controlled. If tyres are underinflated, they flex more, heat up faster, wear unevenly, and the vehicle can become unstable or tip, especially when lifting or turning. If tyres are overinflated, the contact area with the ground is reduced, grip and ride quality suffer, and stability on uneven surfaces is compromised. Regularly maintaining the correct pressure helps prevent these safety risks and keeps handling and stability reliable during everyday operation.
