Kind of a dumb question, but I've never heard it asked before: do tires need to be filled up to the max that all the online charts indicate, or can you use less? For example: my 16.9x24 tires can take 61 gal each (122 gal total). Two 55-gal drums of WW fluid leaves me 6 gallons shy each tire. 3 drums would get me to the max, but leave me with 43 gallons extra. I can't imagine it being a problem going less than the max, but who knows?
We always stop at 10 o clock.. Turn the valve stem to 10 o'clock and fill.. We use alcohol to keep from freezing in winter.. No need to drain in winter time..
