I doubt if they have parrots* but  you do have straight-line thinking. !
Forget the tyres.!
Bolt a 6 inch pvc pipe-leg at each corner.
Make the length such that the tyres are off the ground a few inches, then if one leg collapses, the rig fails safe by resting on the  wheels.
 
 
 Better still, reconfigure so that the trailer is at earth potential and earth it with a good spike in a puddle of pee.

I expect modern tyres have so many ingredients like carbon, steel wire and other polly *compounds that they make poor insulators. If the trailer was parked on a sheet of suitable insulation material it would be alright but it has to be rigid and not move about in windy condx. I have a few ideas but keeping the installation rigid would be the problem even with insulated guy ropes.  It could be back to just using the tower as a support for wire structures. Where would I get proper insulated blocks made to replace the wheels, someone might know of a source.
