Ride height should only be measured with the vehicle on a flat surface after?

Ride height is the vehicle’s static distance from the ground to a reference point, and it must be measured on a level surface with the tires inflated to the manufacturer’s specified pressure. Tire pressure directly affects the tire’s external diameter and how the suspension carries the load; underinflated tires flex more and effectively change the height, while overinflated tires can alter the stiffness and height as well. By ensuring the tires are at the correct pressure, you remove this variable so the measurement reflects the true suspension setting rather than tire shape. Other steps like tire replacement or steering/ toe adjustments don’t guarantee the tires are at the proper diameter or the surface is perfectly flat, so measuring after correcting tire inflation provides the most accurate ride-height result.
