MF tire air pressure

Without any additional weight on the wheel usel the minimum amount and increase 1 psi per 100 lbs of wheel weight. up to the max pressure.

That is what the book says....

Thus 12-16 psi will do.

To test for liquid, turn them until the valve stem is as low as it goes and push the plunger with a tooth pick or piece of baling wire or a small screwdriver. If you get liquid, they have liquid, it you get air they don't have liquid. There is NO WAY for anyone to know whether they have liquid or not without doing that test. There's no predeliction to have or not have liquid. After one of my rear tires split and soaked the tractor with CaCl that rusted it instantly through the paint, no tractor of mine will have Calcium chloride for any reason.

If there is liquid you need a liquid gauge for the air pressure, an ordinary air gauge won't survive the corrosion of the liquid.

There is always some air with the liquid, tires generally are never filled more than 3/4 full otherwise the tire won't stand up to the abuse of 100% liquid. And the ride would be the same as an iron wheel of yore.
