Tires New R4's

Thanks. I'll look into it.

Why does people use this old calcium that destroys metal ?

I’ve completely filled all 4 tires front & rear with a weak antifreeze mix and water in 7 JD 4&5k series tractors.

No rust & non corrosive.

Cost and availability; the rim guard, bio fill are fairly new products.
Even now 50 pounds of calcium chloride is $15-20.
To fill a 18.4-30 tire to 75% is about 103 gallons.
A 3 pound to the gallon mix of calcium stays slush free down to -12 F,
bump it up to 5 pounds per gallon and it's good to - 52F.
So for a tire that size if you went with 4 pounds per gallon and 100 gallons of water,
8 bags of calcium would be about $120 and a person can easily do it themselves on the farm.
And the calcium used to be much less than that price wise.
So well under a $100 per tire to add 900 to 960 pounds per tire.

Your weak antifreeze solution in cold climates would destroy the tires.

I could simply add enough AF to each tire for colder climates.

No Way in the world I’d use that acidic calcium destroying my steel rims.

$700 of antifreeze is no big deal on a high dollar tractor that you certainly don’t want the rims rusting out on

Calcium filled to the correct level will not rust the rims. However, don't want to have any leaking tires either.

Rim Guard has been around for a couple of decades now.

Did you change the fronts and rears to larger tires?

I don’t think that’s true. The correct level includes an air cushion. Calcium in liquid suspension that is in air contact will indeed rust steel.

Calcium level above the top of the rim doesn't rust, steel is below the calcium level. Then as long as there are no leaks that allow the calcium to bleed onto the outside of the rim, no rust.
I'm not sticking up for calcium, but it doesn't deserve the bad rap from incorrect use either.

Well like I said fairly new, especially compared to calcium.

But what is the reason to stick with an old inferior product when there are new and improved products available?
