Ballast Filling tires how much?

[Robert in Pa.]

I am going to fill the rear tires (turf size 33 x 12.5 - 15) on my B-2100. Anyone know how many gallons of windshield washer fluid each tire will hold?

See the Goodyear Farm Tire handbook:

Click on Section 3 (a pdf file) and set search target for page 40. That section shows volume and weight of fill for various tire sizes.
