Calcium in tires, no longer a fan......

[sixdogs]

In your link from post #71 your comment is: the tires were loaded for "a couple of years I was told".
Certainly the seller told you that, and when you drained the WWF, you then assumed that the WWF fluid had caused the wheel corrosion over 2 or 3 years.
My supposition is that someone did load the tires with WWF "a couple of years" prior, but .... prior to that, someone else had kept CaCl in those tires for many additional years.
How old was the tractor when you bought it?

The man who owned it was 96 and passed away suddenly. Note on this is to get a second opinion. He was so meticulous that his shovels and garden tools were wire brushed for the winter and wiped with an oily rag. Magazines back to the 1940's were chronologically categorized.

This was his estate sale and remarks were made that the tractor has been recently "serviced" so in my due diligence I called the dealer. Got a secretary who didn't know much but read me his service card info from the date of purchase (when new) through the last service. I also spoke with the son. That's how I got my dates and feel very confident they are correct. I can smell a rat and am by nature suspicious until proven otherwise. They never had anything but washer fluid in them and in fact, the tires were damaged from spinning prior to the fluid and I had to replace them. He even had the tractor weighed and recorded after filling so I had that as well.



In conversation with the shop that drained them for me, they said everything corroded wheels with some doubts about beet juice. They said wheels with beet juice in them looked like they were sandblasted inside and were shiny steel. Everything else corroded to some degree.

It's all just my two cents here and each of us will do different things. Anything that involves tractors is good; it's just that some is more good than others.

I understand all that you have said.
but...... In my opinion.....something in the story..... is not quite right.
And ..... again....how old was the tractor?

BTW, when I replaced my NaCl corroded 8N rims, I coated them with 2 coats of 2 part marine epoxy.

13 year old rims (with tubes) rusted out from WWF?
The dealer story just does not pass the smell test.

Take a small glass jar: Fill it with water and make strong solution of CaCL ( use NaCl if you can't find CaCl ).
Fill a second small jar with -40 WWF. Put a PLAIN steel nail in each jar.
Look them both over a month later. Advise which one has most rust?

I need some education here.

I thought rust on iron was an oxidative reaction? So, if the glasses are full and with lids, neither nail should have much rust. Once the oxygen is used up, no more rust.

Perhaps someone with more knowledge could explain.

Who said anything about lids?
Non-coated steel nails should be placed vertically, and jars should be partially filled, so that nails would be immersed only partially.
The idea here, being to determine which solution will cause the most rapid rusting.

Not to stray too far off topic but fire sprinkler systems in buildings are plumbed with plain old black pipe and filled to capacity with plain water (no air space) and they will only "rust" a certain amount until the dissolved oxygen is used up and then corrode no further. As Luke stated above.

The extra weight of Rimguard at 11 lbs./gal. might be worth the extra stability on my compact tractor when I have wheels set to narrowest. Windshield washer fluid comes in at 8.5 lbs./gal, at a 24 gal fill/tire, I estimate that to be a net loss of around 2000 lbs./tire....

I think you have a problem with math.

If your tires take 24 gallons, that's a 60# difference. To make a 2000# difference you need 800 gallons, Which is not really a "tractor" tire...

Math problem?
Yep!
800 gallons = 6664 lbs.
240 gal. = 2000 lbs.

The original post was referring to a difference of 2000# using Rim Guard as opposed to Windshield Washer Fluid.

11 - 8.5 = 2.5# difference per gallon. 2000# / 2.5# = 800 gallons.

Or, put another way:
800 gallons of WWF = 6800#
800 gallons of RG = 8800#
Difference = 2000#
