VERY expensive beet juice!

[Soundguy]

... and can't ever be drained if you need less weight.. etc.. etc.

and still has a decent amount of cost involved.

According to a Google search, Rimguard IS beet juice.

What about just "foam-filling" the tires? It is quite heavy, doesn't freeze and can't go flat.

Heavy? What kind of foam is heavy?

 

[Soundguy]

it's a high density poly urethane foam.

does double duty as flat prevention and ballast.. more or less permanent.. so don't have any future plans for them tire casings..

If the extra solutes in beet juice make it heavier than most or all of the current alternatives, I wonder if you could take wwf and add a bunch of corn syrup (HFC can be bought in bulk) to raise the density of the fluid fill? I don't know about possible chemical reactions, effect on freezing point or whether the methanol content would keep yeasts from fermenting the sugar, though.

I wonder if there isn't another medium that might be used? I though sandblasting glass beads would work well, but it looks like they are over $1/lb (though a tire half-full of these would really weigh a lot!).

it's all a compromise.

water is the cheapest.. but it freezes.

then non corrosive ballasts, or mixes to go with water, cost alot.

cacl salt added to the water make it darn heavy, and freeze proof, but corrosive.

a good tube, nad a good well painted rim will make cacl a cheap alternative for decades. keeping in mind if you get a leak, when you tear down to fix, you have alot of cleaning.. plus.. if it has a bad leak in a field.. you will have a dead zone you might want to excavate quickly.

While more weight is desirable, ya gotta consider the incremental cost of getting that last hundred pounds or so. Yes, beet juice is heavier but WWF or methanol mixes are so much less expensive that you will literally be paying about $4-5 bucks a pound for the extra 100 lbs or so difference in weight.

Also, while CaCl is cheap and heavy, the risk of corrosion and the cost of having a tire shop install a tube needs to be considered against what is really a completely safe DITY project with water, methanol mix or WWF.

I have been down the Cal Chloride route on my Ford 861. Never again. It cost me a but load of money to have the wheels replaced.

I also had a co-worker have a tire let go on his 8N while mowing with Cal Chloride in it. Long story short, $800 later for 2 new tires and wheels, disposal cost of Cal Chloride in the other, 2 dump truck loads of top soil to replace the area of his yard that will not grow grass, a half a day for a Back Hoe operator to dig it out. Yea, Cal Chloride is cheap, NOT. lol

I can not get over the cost of WWF in your area. Everything we have around here is -20 or -30, cant remember, but it runs about $1.50 per gallon and maybe $2.00 per gallon even at the quicky mart. Like I said, my bulk oil guy can get me a 55 gallon drum for under $40.

But exactly which high-density foam? I'm pretty sure the words "high-density" only are used in comparison to other types of foam. Foam, by definition, is partly air.

This "high-density" polyurethane foam is 2 lbs/cu ft.
Polyurethane Foam 3
Beet juice is over 80 lbs/cu ft. Roofing tar *floats* in beet juice.

I could add more weight to my tractor by having a grand slam at Denny's than I could by filling a tire with 2lbs/cu ft foam.

why have a tire shop do it. that's a DIY project..

this foam is more like a foam rubber..

our local store that does it charges by the #, 1.60$ per #, and for instance.. a 6.00-16 front holds 70#, an 11.2-28 rear holds 324#

edit:

here are some further numbers to chew on:

a 6.00-16 tire filled with water to 75% holds 6 gallons, and adds 50# water, if you looked at 100% fill, like the foam would fill.. that would be 8g of interior space for foam.

a 11.2-28 tire filled with water to 75% holds 27 gallons, and adds 225# water, if you looked at 100% fill, like the foam would fill.. that would be 36g of interior space for foam.
