Add air-valve at bottom

[Tree-Farmer]

Can you put air in a tire that has liquid in it, when the valve stem is towards the bottom?

I know you’re supposed to put it at the top to add air, but what if you need to add it where it is?

IH 986, rear tire, I was turning on a slope, it was leaning too much for me, I got out and looked and the tire is waaay low. I want to add air to be more comfortable backing out of there, and better for the tire, but the valve stem is towards the bottom.

Can I add air like that? Half my liquid may have leaked out, I’m not sure

Thank you!

You can but I would keep the hose going up from the valve to above the tire to minimize any ballast going back into the hose. I would blow the hose out good after and wash the chuck. If you get it into a gauge (unless you have a "wet" gauge) the gauge will likely fail due to internal corrosion at a later date.

Guessing the ballast may be calcium, if you are losing air and ballast you need to get it fixed or you may be losing a rim.

no problem adding air, it will bubble thru the liquid, just wash your air chuck good when you are done or it will corrode from the calcium.

Is this user error/too much load for the tractor? Or do I have a flat tire? This 15 or 20 foot brush cutter is very heavy for my 986, makes it light in the front. Then I turn on a hill, puts too much weight on one tire, Can it make one tire go flat? Pushes the air/liquid out? I can’t get the picture to upload

Too heavy? Makes tire go flat

How much air pressure do you run in them?

My guess is you are running your tires with too low air pressure

Does it have a tube in it?

(And for those that will comment otherwise, I have a 1977 Ford 7700 that has had calcium chloride in the rears wheels for its whole life with no tubes.)

It would be possible for a tire a little low to want to roll off the rim a bit in the conditions you mention and allow the liquid to leak out a bit on a turn. You would see some leakage somewhere I should think if this is the case?

But it still would need to stem from a low pressure to start with. It does not look like you are abusing or exceeding your tractor/ tire limits with your setup.

With a tube in it, can’t see anything going wrong the way you describe it. Pressure was too low, or a leak developed and you just haven’t noticed the leak yet.

A low tire can look all right and then as you get into a hillside and turn up the hill and have the implement push forward a bit, it can look a whole lot more flat. I’d maybe think this is it from what you describe so far.

Can you put air in a tire that has liquid in it, when the valve stem is towards the bottom?

Yes you can. . But the supplied air pressure must be high enough to overcome the pressure created by the weight of the ballast in the tire. A small 12 volt or battery powered compressor most likely will not produce enough to overcome the pressure produced by the weight placed on the valve core to fill the tire. In layman's terms. It would be like trying to use a 2 ton bottle jack to lift a 50,000 lb truck.

Rear tractor tires are often in the 18-30 psi range, so I would expect any tire inflator to create enough pressure.

The weaker cheaper ones might not create enough volume and burn themselves up before filling a tractor tire. Tho a liquid filled one is only 20% air and easier to fill….

I would -not- use a fancy or small or battery type of inflator with calcium filled tire as the risk of rusting and corroding the inflator is too high, and the likelihood they don’t get the job done is pretty high.

I guess in the end I mostly agree with you, but I’d say it’s because they don’t make enough volume, they should make enough pressure. I suppose that puts me into the internet police nit pickers category of people.

Or, he could have a leak and hadn't noticed until now. It has happened to me a time or two.

A tubeless tire is more likely to lose its seal if run low and rolled on the rim than a tire with a tube in it. Please, tell if your tire has a tube or not just clear that point. Ballast in a tubeless tire should be kept just over the top of the rim when vertical to minimize air reaching the rim.

Your Operator's manual should give you recommended tire pressures for tire size and loading. In general, the same pressure is used in ballasted or unballasted tires. I would guess your tires should be in the 14 to 18 psi range.

The liquid ballast will only have 2 to 4 psi based on static head pressure. The pressure of the "air cushion" above the liquid ballast will be the governing pressure.

A small inflator that can inflate the tire dry, will add air to a wet tire. The drawbacks are that it may take a while due to volume of air needed, and the compressor can be ruined if ballast gets back into the unit. If you must add air with a small battery type compressor it should have a hose long enough to keep the compressor on top of the tire and have the compressor running when hooking and unhooking the hose to keep air flow going towards the tire.

Max pressure on rear tires 12-15psi.

 

[Jim.ME]

Max pressure on rear tires 12-15psi.

Nope, it depends on the tire and loading. 15.5-38s on a JD 2030 can run up to 22 psi for max ballast or heavy rear mounted equipment, for example. Again, Operator's manuals are a wonderful thing
