3. If repeatability is a problem, or you're getting readings that seem wrong, it also helps to have something under the tires which prevents bind & side loading; a few layers of newspaper, or a stainless steel shim between the tire & the pad which will let the tires slip.

I was using the old greased up plastic bags trick that seems to work pretty well for alignment changes.
Rolling the car on/off was a nightmare due to the tower of wood necessary to get the back of the car level w/ the front.
Basically, I needed a flatter location so I could easily roll the car on/off the scales with the supplied ramps.
