Did you get all the tire loading you paid for

[CNC Dan]

Interesting Dan. Not certain how I would apply this to beet juice but interesting none the less.

I think the line of frost/ condensation on the tire my be missleading. As the fluid warms up, from contact with the rubber, the warmer fluid rises to the top. This warmer fluid layer won't cause condensation on the outside of the tire.

You can tell the liquid level by rotating the tire and finding the position where you get 100% liquid when you push in the valve stem instead of a little squirt followed by air. The spec for tires we use on vibratory compactors to give 75% fill (top of rim) actually results in fill to the 10 o'clock position. I checked dozens of machines, tires from both suppliers (Firestone in USA, Goodyear in Europe). The tire companies say the tables are conservative because they don't want over-ballasted tires. I asked what they felt about us putting in the extra ballast so we could advertise a higher weight. They recommended against it unless we closely monitored every fill to insure we didn't go over the rim top. That's not practical on a production line. The problem. With higher fill percentages is tire damage as the air is the cushion. More liquid displacing the sir equals more susceptibility to tire casing damage when hitting a rock, stump, kids bicycles, chainsaw you forgot about, etc.

Scan with an IR thermometer to find the interface

Excellent suggestion!

Why couldn't you just park your tractor with the valve stem at the top to check the air pressure? They don't fill them all the way up.

Not sure I'm catching your drift here. What will this tell me as far as level of fill?

Thump it with your finger like you would a watermelon to test for ripeness.. the density change will be audible if you switch back and forth between the air and the suspected fluid interface.

Or, You could get your drill out and drill a hole just above the suspected interface and see what comes out. air or liquid.. Just kidding...

I'm gonna use the drill method as it is much more definitive. A little Crisco or Spam to fill up the holes and I should be good to go.

Or you could just rotate the tire valve stem and see at what line the fluid starts squirting out... save a little time an NO hole filling! Woo Hoo!

That would take way more time than drilling. Don't forget I have to unscrew the valve core, get on the tractor, drive it so the tire gets positioned, fall off the tractor leaning over looking at when it leaks, chase and remount the tractor and do the same thing again for the other side. What's wrong with you? (I could jack it up but that would be stupid) I have the drill in one hand, the Spam in the other, a few holes and "boom" your done.

The tapping seems to coincide with the alleged fill line defined by frost. Will IR shoot it next and see if that tells me anything..

Now this might sound stupid.. (well not as stupid as the drill and the spam plugs). But I wonder if a studfinder that you calibrate on the upper section of the rubber where you know there is no fluid, and move it in an arc down to the suspected level of the fluid would register the density change just like it does with a wooden stud? I don't know it would work, but what would it hurt to try.. You couldn't look any more ridiculous than chasing down your tractor,.
