Did not read every post here, but last time I needed tires, no one could figure out how to get any jack under anything that would lift the trailer high enough for any tire to clear the ground. And I was NOT going to let anyone put a jack under the axle. I've heard too many horror stories about people doing this and bending the axle.

We ended up using 2 large hydraulic floor jacks, one under each of the leveling system jacks and raised the trailer then. Once high enough, put stationary jacks under the frame in several places. Worked like a champ.
