Fix a flat doesnt balance the tire,it actually makes it worse b/c where the hole inthe tire is more gunk attaches it self

 

I work at a tractor company,they fill the tires with water and methanol.
The "meth" keeps the water from freezing in the winter supposedly.

 

They also use water + calcium chloride to fill tractor and other off-road tires. Supposed to work best in bias ply tires, not so well in radials:

We used to use CC in our tires along with the water but the cost was just too great. Dealing with all the nails on job sites we have alot of punctures. Our tires are filled with the vavle stem at 12 oclock but have 50-60 psi instead of 14 like the link above.
