One of my rear tire looks low. They are loaded from the deal. I’m a newbie with tractors and have posted lots. Trying to learn as much as I can and I have learned lots from OTT. My question is how do I check the air I’m loaded tires and how much air should be in them........... thanks for all the help

Move the tractor until the schrader valve is at the 12-o’clock position (where it’s in the air-pocket that is indicated by the numeral “1” arrowed in the depiction…) and THAT is where the valve should be to check air pressure. (Your Owner’s Manual is your friend.)

To check air pressure rotate the tire until the valve is at the top. That will put air behind the valve. The tire should be no more than 3/4 full so there will be air space. If it's a rear tire it should have about fifteen pounds of pressure.

Valve stem to the top, i still blow a little out the valve by pressing on the pin so as to not get stuff blown into your guage. Rear of a BX i think is 18 psi

And you should probably let a bit of air out to blow out the valve stem before you check the pressure (or blow some air into the stem works)

I believe that there are air gauges that will work better with loaded tires and survive the liquid better than normal gauges.

As russell king mentioned they do make gauges specifically for loaded tires. Milton industries air/water tire pressure gauge is one that is made to check loaded tires. I have one for my tractor, its tires are filled with calcium chloride. and that gauge will measure the pressure with the valve stem at any position. Any fluid that gets into the gauge will make a small mess but a rag or towel over the end when you remove the gauge prevents the mess. When i am done the gauge is cleanable to remove any calcium chloride to prevent it from corroding the gauge. I also have a very basic brass air chuck to inflate the tire if needed that can be cleaned easily.

Your nearest advance auto parts or farm and fleet store may have it in stock. If neither have it you can get it online from the usual places.
