True, if you want to compare my vehicle to another. I put on the same tires as before and was only interested in seeing how much I came up. Yes, OME 2862.Assuming you are using the OME stock height springs, you can't measure from the ground up. Try the bottom of the rim or center of the hub.
When going all the way down to the ground, you will have a lot of variables and errors. Tire size and the PSI will greatly affect the measurements.
