CALCIUM-WATER
TABLE FOR TRACTOR TIRES
Traction can be increased by partially filling tractor tires with a calcium-water
mixture. Volume, weight and minimum operating temperatures are given for
various tire sizes and water-calcium mixtures.
The following table should be used when filling tractor
drive tires for added traction. Water and calcium-water
mixtures are shown with volumes required, total added
tire weight and safe operation temperatures.
If in doubt of your temperature conditions, use the next
strongest mixture. As the majority of your filling cost is
labour not material, extra calcium chloride may be
inexpensive insurance. The table is in imperial units
reflecting the current tire industry practice.
Conversion to metric is as follows:
Imperial gallons multiplied by 4.5 = litres (1).
Pounds divided by 2.2 = kilograms (kg).
For maximum traction, tube type tires should be
filled to the value stem level when the tire is upright
and the stem in the highest position. This is
considered a 75% fill. For tubeless tires, it is
recommended that the liquid level be maintained at
90% filling level so that the rim is always
completely covered. This will lessen the possibility
of rim corrosion.
Water-calcium mixtures are pumped into the tire with the valve stem in the highest position.

2) Values are for “fill to valve stem” level, 75% fill (tube tires). For tubeless tires, fill to 90% (increase values 20%).
3) Volumes are imperial gallons.
NOTE: 1) Values are for Type I Calcium Chloride (77% CaC12) . For Type II (94% CaC12) reduce the “lb. CaC12” weights 25%.
