How do you replace all the tires on a 5th wheel?

I use Lynx leveler blocks to build ramps under both tires on one axle. Loosen lug nuts on other axles tires, pull up on ramps, remove two tires (one on each side). Take tires to shop for replacement. Upon return, grease wheel bearings, check brake parts, and then put new tires on TT. I then repeat for second set the following day. Note this requires TWO vehicles, as I leave TV and TT attached to do this.

I do the axle with the best old tire last, as that becomes my new spare.
