See full version: Setting trailer on jack stands
Not everyone uses a chumpy tongue jack for their trailer. I have used the method many times to raise a trailer, w/boat, off the ground. The only suggestion would be to add a jack stand to the tongue to steady and support the load. more
If raising the front of the trailer doesn't get the wheels off the ground, then you'll need a buddy and a couple of floor jacks under each side of the frame, just forward of the wheels. Raise the trailer from both sides simultaneously, then place jack stands under the frame. When you're done, the trailer is safe for you to work on/under. By the way, an impact wrench makes removal of the hangers and bunk support brackets. Some, you may need to use a cold chisel to break off the bolts. Corrosion is pain! When you rebuild, take your time and buy good hardware -- galvanized, stainless if possible. [links]
Ayuh. Lower the tongue jack, block the aft end of the frame, raise the tongue jack, 'n remove yer tires.

i took my boat to the launch. dropped it in the water. tied it to the dock here
He drug the boat back off the trailer with the tractor until the bow was at the end/back of the trailer, we jacked up the bow to get it up off the trailer (we used a 4x4 on the jack), then the co worker pulled the trailer out from under the boat. The trailer was hooked to a vehicle during all of this by the way.
doing the trlr is fast and easy. [links]
4/ to reload, just reverse the procedure.
If I leave it for more than a couple hours I use five jack stands. two under the transom corners, two on the mid part of the hull, and one under the keel near the bow. Make sure the stands aren't going to slide out sideways or sink into soft ground. more
I've always thought it would be a good idea to put the trailer on blocks for the winter to prevent flat spotting tires, BUT I've never gotten around to doing it. If I ever do I'll probably use a couple of jack-stands or cement blocks to rest in on. Good Luck!
To answer the question. don't waste your time. The current quality of tires precludes this troublesome task. Used to do it religiously years ago, but not needed any more. here
