I have a support which goes underneath the tank area. It
has two scissor jacks, with their screws connected
together with a wooden board across the top onto which I
also place a spongey mat.
With this I can jack up the whole of the rear of the
aircraft (with the weight on the nose-wheel and the jacks)
until both main wheels are off the ground. Then dealing
with the wheel and tyres is easy !
I could include a picture - I would need to take it and
the fuselage is not available at the moment :-(
I had a similar "outside edge" wear problem. I have been
told it is because the gear legs were not installed
correctly ! I changed the tyres at 175 hours, but all I
actually did was change them on their rims, so that the
worn part is now on the inside edge. I reckon on that
basis the tyres will last for 350 hours !
Please note that changing left to right without changing
on the rims will leave the worn part still on the outside !!
The tyres are the standard ones.
