Tires are filled with beet juice. Freeze pt= -35. No tubes.
Local tire shop can handle/uses CaCl2 in tubes.
The beet juice is the heaviest fluid you can put in. I think about 11pounds per gallon. Since it is in there,I would not replace with CACl2. since the Rimguard is not caustic
If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
