Why is it important for the kingpin to have an outward tilt?

Having an outward tilt on the kingpin is crucial as it enhances steering response. This design feature allows for better handling and maneuverability of the vehicle. When the kingpin is tilted outward, it helps in creating a more favorable angle for the steering system, leading to increased responsiveness when making turns or changes in direction. This is particularly important for commercial vehicles, which often need to navigate tight spaces and perform precise maneuvers.

The outward tilt also helps in distributing the load more evenly across the tires, which can improve overall tire performance and reduce wear. However, the primary reason for this design is the enhancement of steering response, making it easier for drivers to control the vehicle effectively.
