The article discusses how tilting vehicles or raising individual wheels can affect the accuracy of measuring wheel loads. If one wheel of an axle is raised, it can lead to significant errors in estimating axle loads from individual wheel loads. To ensure accurate measurements, it is recommended to set the wheel-weighing platform in a pit so that all wheels of vehicles being weighed are in the same horizontal plane. This information is crucial for designing pavements and overlays, especially in developing countries where axle-load surveys are commonly used.
