Also has any body added water to the rear tires for extra traction
hi schalfback, yes I added -20* Windshield Washer Fluid to my tires for ballast. the results of ride and traction were immediately noticed by me as an improvement.
→ water - 8.35 pounds per gallon, rim rust over the long term will be an issue
→ windshield washer fluid - helps prevent rim rust and has a lower freeze point than water
→ antifreeze - helps prevent rim rust and the freeze point can be regulated to meet climatic conditions
→ Calcium Chloride - about 11.5 pounds per gallon, highly corrosive, tubes recommended
→ Rim Guard - about 10.8 pounds per gallon, No rim rust, area availability?
the cost of antifreeze or WWF was very close, i chose WWF because it should be more environmental friendly than the antifreeze, at the time of the inevitable tire puncture.
there are many posts detailing the loading of tires for ballast with allot more detail.
