Rimguard vs. Methanol

[crazyal]

It does not persist in the ground and is minimally toxic to plants when spilled on them. The toxicity of methanol is primarily associated with direct ingestion by humans (?other mammals) in quantities that may not seem large (10-40ml of pure methanol) but these quantities would be very unlikely to be ingested by any animal as the leaking tire fluid would drain immediately into the ground. It does not persist in the soil. Basically, except for the toxicity induced by hepatic metabolism, methanol is really no more toxic than ethanol. I'm not sure there are studies to quote but it is likely no worse for the environment than spilling a similar quantity of wine (15% ethanol) into the ground.

WWF is toxic. It has a high level of VOCs in it. It's not just the Methanol.

From the fine folks that brought us CARB. :confused2:

1) Are you serious? Plants emit hundreds or thousands of times more VOCs than all man made VOCs
2) Methanol is itself a volatile organic compound and is the only substantial ingredient other than water in WWF. What are the other VOC's you are concerned about?
3) WWF is toxic only if ingested (methanol remember).
4) EPA says methanol has basically no impact on fish or terrestrial animals from environmental exposure (as opposed to actual ingestion).
5) Even in California they spray WWF by the millions of gallons all over roads
6) We are talking about contained use of methanol in tractor tires where there might be a small risk of leakage but where for practical purposes it will rarely get into the environment at all.
7) TBN members fart more VOCs in a day than would be released by leakage of WWF or methanol/water from their tractor tires in a year.

Hey!!! my farts are clean. No VOC's here.

So your argument is that other things also emit VOCs and the chance of it leaking out is not all that great. Not much of an argument when a slightly more expensive yet safe alternative can easily be had.

crazyal, do you use ethylene glycol or propylene glycol in your vehicles?

My argument is that given the specifics of methanol use in tractor tire ballast that worrying about VOCs is beyond silly. This country produces over 2.5 Billion gallons of methanol a year. Worrying that ten or twenty gallons might possibly get spilled into a field is hard to comprehend in the big picture especially when millions of cars are spraying it on their windshields on a regular basis.

The "slightly more expensive" alternative can cost five or six times what self installed WWF costs as for practical purposes RimGuard can only be installed by dealers with relatively special equipment. I have nothing against RimGuard and in fact used it in one of my tractors but WWF is an economical and effective substitute that many people use successfully.

When did every body get so worried about a little gas or methinal spilled on the ground? Must be one of those suburbinite things,people got a 30 hp 4 wd tractor on a 2 acre lot?,,yeah,guess if thats the only room I had,wouldn't want to spill much on that...

Hey...it's only about 23 HP and it's 3 acres :thumbsup: Methanol spillage, no problem. As for spilling gas, that's a different story for a different day.

Everyone is talking about Rim Guard not being toxic and/or methanol being toxic. They are both toxic, but they are not of concern at the amount being used (especially if you are using highly diluted methanol in WWF). So don't let "toxicity" or "environmentally friendliness" be your deciding factor.

Methanol (CH3-OH) breaks down naturally in sunlight to carbon dioxide (CO2) and water (H2O).

Rim Guard is calcium chloride (CaCl) with some proprietary rust inhibitors (see link below), and CaCl crystals are sold as de-icer at Lowes and Home Depot.

CaCl has a reported LD50 of 1000 mg/kg based on oral ingestion and methanol has an LD50 of 5600 mg/kg based on oral ingestion. It takes 5x more methanol to exibit death to 50% of the test organisms than calcium chloride (LD50 = a lethal dose to 50% of the test population - this is how chemicals are classified for toxicity). On this dose based example, CaCl is more toxic. (However, methanol is almost certainly more acutely toxic).

Here is the MSDS for Rim Guard (click on the MSDS .PDF file on the right column).
BallastStar - RIM GUARD Spec Sheet

Here are the MSDSs for methanol and CaCl that show the oral LD50:
METHYL ALCOHOL

CALCIUM CHLORIDE, PELLETS

WoW no-one ever said that RimGuard was actually Calcium Cloride with some propriatary rust inhibitors before.. looks like it might be more toxic than methanol after all! hat about the "beet juice" rumor.? I have always heard the RimGuard was mostly beet juice, not according to the MSDS sheet.

Very Enlightning post, Thanks.
Well does anyone know anything bad about the Propylene Glycol? other than it cost's an arm and a leg:laughing:
