Loaded tire pressure gauge

Man no good
I never drain.

That looks like calcium chloride Which I’d never use.

It’s Rim Guard. I didn’t want to drain it but aired the tire up to much because of a bad gauge.

Does it matter? Isn't pressure form the same vessel the same whether it is liquid or air?

The liquid won't compress like the air will so when you run over a rock the tire will take a lot more abuse without air. That's the way I was told....

I believe you were told correctly.

Thanks for the question. I think you are correct, however, what matters is that the fluid gunks up the works of most "regular" tire pressure gauges.

You can purchase stick style gauges meant for use with filled tires. These are spring loaded so you must read pressure with gauge held on the stem.

Another option is gauge with a foot or two of hose between stem connection and gauge. Keep gauge higher than valve stem and in theory fluid never gets to the gauge.

Thank you.

I roll the tire so stem in at top, then give it a short shot of air pressure to clear the liquid. Some liquids will ruin a tire pressure gauge, so if necessary I can always bleed out excess pressure.
In fact i just bought an analog 0-60 air pressure gauge($10) with a bleed plunger on the side of the tube. Now it's much easier to maintain 8-12 PSI in my ZTR lawn mower tires and tractor tires.

Thanks for the reply.

You have to be QUICK when adding AND removing your air Chuck.

I have 16 antifreeze mix fluid filled tires on tractors & Zero mowers here on the farm.

Napa makes a springloaded gauge for liquid that works great.
You have to keep it applied on stem to read it.

Thank you.

Yep... check with the stems up if you are worried about fluid coming out. I just use a standard dial pressure gauge on mine without any problems. Mine are about 80% filled with used antifreeze from a truck shop 20 yrs ago, and they were glad to get rid of it, since they didn't have to pay the disposal fee.

The digital one on the right wont work ( I ruined one with beet juice...)
The old school one on the left works fine, its even says air and water.
