The solution indicated above, when using a commercial calcium chloride flake of 77-80%, should protect the
tire against freezing down to 30F. below zero. Solution strength can be tested with a battery hydrometer.
Reading at 60F. should be 1218.
It is recommended that the rear tires be hydro-inflated to the above table if optional counterweight is not
used. It is not permissible to use both hydroinflation and optional counterweight.
