I didn't like the weights I had. Couldn't find any cast iron. Used anti freeze was going to cost $2 a gallon.
So I've been watching for a sale on windshield washer fluid. A friend of mine told me they had it on sale at Menards for $1.37/a gal.
I just got home with 120 gallons.
16.9X24 tires. I'm thinking WWF may be slightly lighter than water but it still ought to add about 450-500 lbs/tire.
