Best way to remove all methanol from tires.

[LD48750]

Whether it is 40% or 75%, Rimguard will always be heavier. I am in the Ozarks. Nothing is flat. Methanol is not heavy enough. And, being in the hills, I don't want any added weight above the axles. Both the manual and the dealer say to fill only to 40%. I am inclined to go as far as 50%, to the axles, but not above. At 50%, the difference between methanol and Rimguard is an added 180 pounds. Thanks, Larry

I can't find a 40% recommendation for ANY tire fill anyplace.
I sure would like to see a screenshot of that manual page.

Now wondering if the 40% is the recommended MIX of water & methanol to get to where it won't freeze.
That would leave 60% water to the 75% fill that the OP isn't figuring into his weight calculations.

OK - I found the Op Manual for the Kubota L4701. In the section regarding rear tire ballast.

It says( I paraphrase here ) - when using any acceptable type of liquid ballast - DO NOT fill the rear tire more than 75% of it volume with the liquid ballast.

Page 61 of the L4701 Operators Manual.

I, also, want to see a screen shot of the Op Manual that shows the 40%.

I guess I did say found in my Kubota manual. And you are right, 40% is not in the Kubota manual, I was mistaken.

Kubota only mentions 75% as a MAXIUM fill. It does not make a preferred recommendation. Leaves that to the dealer.

The information below is from the salesman manual posted online by John Deere. You can read their Preferred recommendation just after the IMPORTANT below.

This posting can be found here: Using liquid ballast in tires

I suspect that may be because of increased law suits regarding ballast experienced in more recent years. Looks like the link is dated 2006, but I think the last update was stated as 2013. The very first statement clearly displays the JD concern about using liquid.
And I an not saying I agree with that. The benefits of that ballast (for me) clearly outweighs the down side and ride performance.

But regardless, I do not want excess weight above the axle.

​ ​ IMPORTANT:Liquid ballast is not preferred in rear tires. Liquid weight greatly increases tire stiffness at lower operating pressures and greatly reduces ride performance. In some cases liquid will be needed in the front tires to achieve the correct weight splits with some implements for field operation and transporting. CAUTION: Installing liquid ballast requires special equipment and training. See your John Deere dealer or tire service store. IMPORTANT: Never fill any tire to more than 90% full. More solution could damage tire. Use of water or calcium chloride solution can be used to provide economical ballast. A mixture of 3.5 lb. of calcium chloride per U.S. gal. (0.42 kg per liter) will not freeze solid above -50 F (-45 C). However, liquid ballast is not recommended because it results in harsh ride, difficulty in handling, spills if flats occur, and when used in rear tires can result in greater susceptibility to power hop. CAUTION: Avoid possible injury due to losing control of tractor. Limit transport speed to 20 mph (32 km/h) when using liquid ballast. Note:Use of alcohol as liquid ballast is not recommended. Calcium chloride solution is heavier and more economical.IMPORTANT: A maximum liquid fill of 40 percent is recommended in rear tires for better tractor performance instead of the previous recommendation of 75 percent fill. Fill tube-type or tubeless tires up to valve level (40 percent full) with valve (A) shown above, in the 4 o'clock position. When putting liquid in either front or rear tires, make sure both front tires have the same amount of liquid fill and/or all rear tires have the same amount of liquid fill.

From Kubota Manual.

position).

(B) Incorrect-100% Full Water can not be

Sloshing ballast in a 40% filled tire negates any center of gravity gains compared to 80% filled tire. It’s the dynamic forces that overturn tractors more than the static.

Well Smokey,
That is a good property to point out. Hadn't thought of that. There would be a lot more room for movement. I am at 40% methanol now and don't feel any problems. But that doesn't mean the heavier mass of Rimguard would be ok.. It might become a problem. Thanks, Good point I must consider. I also was looking into this because the nearest Rimguard dealer is 3.5 hrs away. It would take two trips to get it done. It is also my understanding that Rimguard is sold by the pound (sometimes gallon) installed, regardless if you install it (which I will not do. Could turn into a big mess and unsafe probably). No difference in cost. Thanks, Larry

Put tubes in and fill with water and anti freeze. Problem solved. I have a 1958 tractor here with that mix.

 

[LD48750]

I am really curious now.

OP..Would you jack up your tractor just to the point you take the weight off the tire.
Rotate the valve stem to the 12 O'clock .
Remove valve stem and rotate until you get liquid.
Let us know if that isn't until you get to 4 O'clock.

Put liquid on a piece of paper & see if it will burn.

I think I understand your safety concerns but don't understand why the hundreds of thousands of farmers & tractor owners that have been running at 75% haven't had the problem you fear.

I can see it now. Somebody on a JD tractor tipped over. His rear tires were 75% full of something. A clever shyster convinced the jury that 75% full created an imbalance.

Just as a note - I've had two tractors out here for forty years. Brand new Ford 1700 4WD for 27 years. Now a 2009 Kubota M6040. Both had/have filled rear tires. The Ford had NaCl - the Kubota has Rim Guard.

What have I noticed. Increased stability with filled rear tires.

However - you are absolutely correct on the 40% in the data you found. I think this is a knee-jerk reaction to legal action.

My sincere feeling - you will be shorting yourself if you only fill to the 40% level. You should NEVER be running horizontal on a slope on a tractor where the difference between 40% and 75% might cause the tractor to upset.

Most likely - you are on a slope > rear wheel goes into a hole > over you go. Tires filled to 40% OR 75% will make no difference. Tire filled to 40% IS NOT going to save you. Tire filled to 75% WILL NOT increase the chance of this happening.

I did not say anything about others using 75%. I did say that in the environment I was told 40% by the dealer. THAT is not my concern. I was asked to POST a page showing preference to 40%. I did so. I even stated that I did not agree with JD. AND in you are curious, read my post. I stated that I would not remove all the methanol nor install Rimguard myself. The OP was about learning if I could remove enough methanol to put Rimguard WITHOUT going as far as removing the tires and rims. I also posted - what I was told by a tire service. And got the quote to have them install Rimguard by removing the tires and rims.

Not sure what you are getting at with all the rest of all it. It was part of the Manual for Kubota and JD post I was asked to find.

I cannot believe how off track we can get here. I DO NOT care if someone uses 75%. If my operating environment were more flat, I would also. It would be soooo easy and cheap to solve a ballast issue.

These are very helpful statements and deserve a lot of consideration. I would really like to add more. And what you are saying may be the best answer. I have never heard anyone say 75% is an issue. i was also surprised to read that. I think you aould be hard pressed to find a farmer who plows with empty tires - traction is needed.

But I think if I were a tractor manufacturer, I would be careful about making any recommendation regarding ballast that did not involve a tractor use and terrain involved.

I agree with you about the legal issues faced by dealers. I think that is why they start out with a We don't recommend (anything). BUT be sure to use ballast.

Thanks for the suggestions.
