I had to narrow my M4700 to fit on my trailer. About the same size tire and filled.
The essential tool is the nut holding the front tire
But that took about 30 years to grow.
The two of us managed to turn one rear tire around with a fair amount of difficulty using only a farm jack for lifting the tire. We hooked the farm jack under the lip of the rim of the tire and wiggled it off, then turned it around, lifted it back up and remounted it. IT was a bear of a job. We did not have any place to hang a hoist, this was on a suburban concrete driveway.
We tried positioning it with a pallet jack but couldn't get it lined up.
IF you can rig up a hoist far above the tire and hoist it without interfering with the bolts (like wrapping a rope around it) it should be relatively easy.
DON'T LET IT FALL OVER!!
