Reasonably level ground, one lug wrench, one jack and 4 jack stands are all that are needed to do the job.
One jack stand under each end of each axle under the leaf springs will support the trailer safely with all 4 wheels off.
Do not jack up the axle by the middle of the axle!
Break the lug nuts loose. Jack up each axle by the end of the axle and place jack stand next to the jack. Move jack to new location and repeat until all 4 ends of axles are on the jack stands. Remove wheels and take to tire store for fitment of new tires. Reverse process and done.
This gets my vote. I know the OP is just trying to be careful and avoid problems, but is over thinking this, in my opinion. If the trailer could not withstand the above procedure done with just a little bit of care, just imagine what would happen the first time it rode across a tiny bump in the road.

Sure glad I watched garage install my new XPS tires. Took my rig to commercial truck tire specialists. They were about to jack axel up directly in center of trailer. When I questioned them they said they were doing one axel at a time. Luckily I caught them in time and explained that they must jack as close to wheels as possible. Averted bent axles.
Then after asking to have them balanced in the office I asked them as they were about to reinstall the tires and floor guys stated they never balance trailer wheels. Had to insist they balance mine.
Feel sorry for the uninformed consumers out there.
Does no one know how to do anything right anymore?
I pulled 1 wheel at a time off at the local Sams Club, by the time they were done mounting the tire and balancing I was ready with the next wheel position, bottle jack under the spring pack, was done within a couple of hours.

Man! You must live a long way from the tire shop to want to remove and take all of your wheels at once. I would be afraid to remove both on one side alone. Just because you take it to the tire shop doesn't mean you can't tell them how you want it jacked. Maybe call them first, they might have a different way of doing it alltogether. Some of the pros believe in ramping. I would never jack under the axle alone. Either ramp one wheel or jack the frame first. These axles aren't meant to be jacked with the whole weight of the trailer on them. What ever way you go if you are hitched it will be safer and more stable. If you take it to a tire shop they should be able to zip them off mount and balance and zip them on quicker than you can run back and forth. Tom

When I replaced the tires on my fiver, I went to a commercial tire shop. They knew what they were doing, jacked up the trailer in the right place, removed one tire at a time, used metal valve stems, balanced the tires, even checked the inflation in the spare. I stood around and drank a Coca-Cola.

Last year I upgraded to a better wheel/tire combo and had them shipped from this company http://www.trailertiresandwheels.com/ When they arrived, I changed out one wheel at a time.......put my bottle jack where the leaf spring attatches to the axle and lifted the wheel off the ground. Piece of cake........ Prior to this when replacing my shackels and adding wet bolts I did have to lift one side of the fiver @ a time on the I beams to take the weight off of the springs. I don't know about your fiver but I have a 39 footer & it is one heavy son of a gun........it was no easy job doing that!!! I also had to buy a heavy duty 10 ton bottle jack & heavy duty jack stands. I think that you are personally making things way more difficult than necessary, when you can just simply jack one wheel @ a time from under the axel @ your leaf spring.What would you do if you had a flat on the side of the road.....lift the whole trailer up from the frame???......I don't think so. Just my opinion & you can do what you want.
I would just jack up one tire at the axle where the spring is at and remove that tire and put on the spare. Then go around to the other side and jack one tire up there and remove that tire but leave the jack in place.
Then take the two tires to NTB and get them replaced with new tires - balanced and new steel stems etc... Bring them back home and mount on the trailer then two off the remaining two tires and take them to town and be be done with it...
I would leave all the stab jacks in place just like you when are when parked. You will be able to jack up one tire at a time and clear the ground to remove the tire without messing with anything else. You can run over a couple of those leveling pastic thingies with one tire and that will make the other tire on that same side clear the ground... You will not be jacking up more than a few inches to make a tire clear the ground.
I always deal with NTB (National Tire) or whatever their name is now and I usually take them two tires at a time... If you want to inspect the brakes and all just jack up one tire, pull the tire and have a look see. That is all they do when they do a safetly inspection... That all should be done when you get your safety inspection anyway...
I would not JACK up the whole trailer - only a wheel at a time at the axle next to the wheel... The suspension springs etc will keep you from bending any frames or whatever else you might be concerned about. To me jacking up the whole trailer at the frames would be the worse thing I could do with my trailer about bending my frames let alone being a very UNSAFE thing to do in my backyard...

I'm also with Fred in that other people wrenching on my vehicles gives me the creeps. Among the many good suggestions, I second the notion of keeping the TV attached during trailer jacking. And while I'm at it I check the wheel bearings for free play and wire brush the wheels prior to balancing (tire busters need a gun to their head before they'll clean wheels properly). And while the wheels are off I pull the drums and look over the brake shoes and springs (and wiring in the case of trailers). Then of course the proper torque on the wheel fasteners is sure only if I do it.
