Really not a lot of reason to fluid filled tires on a backhoe tractive force is usually not the primary requirement. however I would almost be tempted to have my steer tires rubber foam filled on it because even though they are 14 ply and inflated to 60 lbs I've seen them mashed almost flat when lifting things I can only imagine the pressure inside them at that point.
I have the front tires on my 8n tractor rubber foam filled because after I put the new tires on I had to repair both of them a dozen times in a week due to thorns Now I would like to rubber fill the rear tires but at $400.00 each to fill them that currently is way low on the budgetary scale.
Filling them with rubber foam would be like filling them with 12lb per gallon fluid it would add a lot of useable tractive weight and never have a flat again I have a flat on the 1 new rear tire I put on is right now
