Couple things. One-I hope you have metal valve stems. Some rubber ones the core will un-glue from the rubber and come out. I found this out the hard way and the JD dealer who did it "never had that happen before" even though it happened on all 6 of my tires that they had charged me new valve stems for.
Next-the stuff is pretty sticky. If you check your tires you best use that gauge only for that set of tires as it might not read as good after that. Wash the gauge with warm water after as well. Even with the stem at the top of the tire you will have some in the stem. Unless you add air as well while at the top first you won't blow it out of the stem.
Don't know how full your tires were when they filled. Sometimes they go all the way full with one bead broke to fill. Othertimes they will fill to the top of the rim with the top of the tire as the air-gap.
In the winter you need to run more PSI. Not a lot of air so it can contract some loosing PSI. I actually had my one tire spin on the rim. I locked the diff in to get back to the shop. Didn't leak out-but I had to put more air in to prevent spinning the rim.
I don't measure the PSI on the rears other then making sure there is enough air to prevent spinning the rim. Fronts I more worry about with the heavy blower up front. I experimented putting fluid up front to see how much I would gain. 20 lb on my 332 per front with rimgaurd. With that and wheel weights I have another 100 lbs to help guide the blower rather then the blower guide the tractor. It has helped a lot.
I won't fill my fronts ever again as the cost is too much for too little. You pay for the labor mroe then the fluid.
Most places that deal with tractor tires will have a gauge that goes low enough. Digital gauges often go low enough and high enough.
