Tires Tire pressure

[Frisch]

I have a JD 5400 and need to know what the front tire pressure should be. One tire has deflated a couple of times during maneuvering . The tires are tubeless

What's it say on the side of the tire ?

If you're losing pressure, it might be the valve cores leaking. They're cheap and so is the tool used to replace them.
As far as the pressure, Willl has the idea. If your 5400 has a loader, up that pressure a bit.

Tire pressure pages from 5400 operator manual. Includes pressures differences for heavy implements as Roy notes.

I also would like to know the required tire pressure on my 755. I've noticed a loss of pressure in the front after using the loader to move some gravel around the place. I only received the manual for the tractor but nothing for the 70 loader (or the MMM for that matter). I was told by the seller that the tires are filled w/liquid and wonder if this would also impact the required tire pressure making it not sensible to just "up the pressure for heavy loads". I know it wasn't calcium but maybe washer fluid or antifreeze? Some such other automotive liquid. Any advice would be greatly appreciated. The tires are turf and the largest option applicable to the 755. Not sure if it matters that it is the MFWD.

Liquid filled makes no difference to setting tire pressure. Fill it to the Max permitted on the side of the tire wall (max. inflation pressure)if you are running a FEL. Every tire size and type requires different pressures. I have always found the info on the tire side wall in very small writing but always there.
Rotate the tire so the stem is at top dead center (12 o'clock) and check the pressure. This should keep any ballast liquid from getting in your gauge if it is properly filled @ not more than 75%. This would put the liquid level about even with the valve core so you should be able to add or reduce pressure with minimal ballast loss.
