I have a different approach - I use a snowmobile/motorcycle jack (without the
support bars) to lift the wing. Before I do so, I block the other two wheels on
both front and rear, so the plane doesn't pivot and I make sure the other wing
is clear underneath as it pivots down a good bit. I made a special box (one for
each side as the curvature is reversed from side to side) for the top of the
jack that fits the wing curvature and is padded to protect the skin. You also
need additional height to be able to lift the jack enough to lift the wheel off
the grown. The box centered on the spar.
This has the following advantages: it is safer as the plane can move if lifted
by the jack only, which allows the landing gear to move inward and possibly
fall, you can jack up the wheel to check the tire pressure without rolling the
plane to get the fill value at the bottom of the wheel, it is easier to check
that the roller bearing races aren't rotating on the axle, and when working on
the brakes you have more head room (oh, my aching back). In addition, you don't
have to remove the cotter pin to jack the wheel up - always a pain to get out
and put in.
The jack was about $250 at Harbor Freight, and it has a locking mechanism to
ensure it won't fail if hydraulic pressure is lost.
If there is any interest, I can post pictures.

Subject: Europa-List: Re: Europa tri-gear wheel change
From: "JonathanMilbank" <jdmilbank@yahoo.co.uk>
Just a word of caution to anyone new to the Europa tri-gear and changing a
wheel or repairing a tire for the first time. When jacking up on the piece of
metal rod or breaker bar which you've inserted into the hollow axle, place the
scissor/trolley jack a couple of inches away from the end.
While the wheel is being jacked up, it is likely that once the tire is off the
ground, the bar will not be horizontal and therefore won't be at a right angle
to the jack. The higher that the jack is raised, the greater the potential for
it to slip sideways and drop the aircraft.
Therefore I have a block of concrete or wood ready to slip under the
undercarriage leg where the brake caliper attaches, as soon as I've loosened
the brake disc and wheel and moved them out of the way. Only after the flange
for securing the caliper is resting on the block, do I breathe easier.
