Frozen filled tires - how can you tell?

[FTG-05]

Look at the chart in this PDF. 20% propylene glycol will get you down to +20 degrees F. You approximately 10% (guestimated?) mix would do very little

Except it didn't freeze after a week and a half of well below freezing temps. So I must have had enough or the original fluid left over from the previous fill (clear, colorless and tasteless) also had antifreezing properties.

Keep in mind pure water in your tires is sure not going to freeze the first night you get below 32. It will take some time, due to the large mass of fluid. And any sunlight at all on the tires will raise their temp considerably due to "heat soak".

How many times do I have to say it: A week and a half of subfreezing temps, most of them below 20 degrees.

No sunlight since I didn't use the tractor, I never opened that shop door, which is insulated. Plus, it was mostly cloudy.

Something worked or something happened and I'm dang glad it did.

Bottom line is you never just add some RV antifreeze to a large amount of water in your tire. You always use full strength, and that might not be enough depending on the mix and where you live. If you "just add some", you might just have well pixxed in the tire. The results will be about the same.

Except it worked - just like my BIL said it would. Funny that.

FTG, there is only one possible explanation. Your tractor was abducted by aliens,
cosmically weatherproofed and brought back to you.

Clearly you had some good stuff in those tires already.

Probably had some methanol in there.

Most of the RV antifreeze I find is Ethanol now.

Another "possible explanation": The OP's BIL is a farmer/industrial chemist, who has thoroughly researched the formulation of RV antifreeze, and has studied it's usage characteristics.

The water left in the tires from the first fill contained some clear AF type that was tasteless as well. The liquid ballast that came out was both clear and tasteless. .

You tasted the fluid in the tires?

Is methanol clear, colorless and tasteless? No salty or sugary, it just tasted like plain water. Obliviously, not know what it was, it was just a very small amount. So far, it doesn't appear to have affected me affected me affected me.
