fluid in tire

dale r · May 31, 2017

How much fluid should be added to a 13.6-28 tire. The tire holds 47 gallon but I think there needs to be some air space.
thanks

There are charts for that, but generally the tire gets filled to 75% with fluid. With the rim turned so the valve is at the top, that is the fluid line.

It depends on how much weight you want. With the valve stem at the top, I fill it to the valve stem. You need to leave some air to absorb shocks.

It is my understanding that the charts show what you can practically get in the tire, not what it would hold if you could somehow manage to fill it solid with fluid.

Thus, if the chart says 47 gallons, that is 47 gallons filled with the appropriate air space.

I could be wrong, but I don't think so.

I recall we usually put about a barrel ful in a 12x38 same tire on a WD 35 and 800 Ford. We never completely filled the tire and I never heard of anyone filling completely.

Agree with the others saying 75%. On one of my garden tractors I made a tiny air tube bleader gizmo that went through the valve fitting and let the air bleed as you filled. You could get the water to air ratio about 95% full. Man o man was the rear of that tractor heavy !! Trouble was it rode like a brick ,,,, house. Let the water out to the top of the rim. You need that 25% air bubble to preserve your kidneys. Lots of people use beet juice. Will not rot your rims. Also check out WINTER blend washer fluid good to under zero degrees. Another way that some will scream about is used antifreeze from the junkyard. You must monitor things for leaks . CAUTION. NEEDED! The fluid will dramatically lower the center of gravity with your tractor. If you do your lawn/ garden tractor you can mow with your rear sliding out of the seat and the tires still grip! One thing I did is go to NAPA and grab a bottle of radiator cooling system rust inhibitor. Couple of bucks a bottle. Squirt a bottle of that into each tire. Will REALLY save your precious rims.

Here's a chart that shows putting 43 gallons in a 13.6-28 tire.
