Tires Ballast in tires

[Loadstar]

Weight in tires is not ballast. Ballast is counter balance. You cannot get counter balance without weight behind the rear axle.

Lol Ballast is under train tracks, or a part in a fluorescent light too.

Messicks has a good section on tire ballast including a chart for the number of gallons of liquid by tire size. It gives weight based on gallons of water. Calcium Chloride and Beet Juice will have weight in the 11 pounds per gallon range. Water will be in the 8.4 pounds per gallon range. Methanol will be 6 pounds per gallon - it is usually mixed with water so the weight will be more in the 8 pounds per gallon. Antifreeze and windshield washer fluid will be sound the weight of water.

What's the best way to avoid rim rot?

Stay away form calcium chloride. If you get a puncture and the stuff leaks between the tube and rim it will rust the rim quickly

The best way to avoid rim rot is to maintain your tires with proper air pressure. Keep tubes in good shape. Make sure valve stems don't leak. Keep valve cores tight.

Calcium Chloride is the big culprit for rim rot. It is a corrosive salt. We have a 1972 Massey Ferguson that has had calcium Chloride loaded fronts and rears. We had new tires installed a little over a year ago and the rims were fine. The tires did have tubes in them. At the same time we had the tires replaced on our IH 140, the rims had to be replaced because the calcium chloride had eaten them around the valve stem. The valve stems had been giving trouble on that tractor for years. The difference was we should have had the tubes replaced in he 140 when they started leaking. Clean any leaking calcium chloride off as soon as possible. FWIW we reused the calcium chloride in all of those tires with new tubes. I have calcium chloride in my Kubota MX5100. An alternative just wasn't available.

Beet juice or Rim Guard is non corrosive and environmentally friendly. It is somewhat more expensive as I understand it and may not be universally available.

I dont know why it double posted. We have always had calcium and have replaced a lot of rims. Thanks for the pointers.

Funny, my OM has a section on adding liquid ballast.
There are different types of ballast, for different reasons, ie front ballast.
Stability on slopes, is one benefit of loaded tires.
I will agree that to best counter balance something like a loader, the weight must be aft of the rear axle.
Weight boxes, hung on the 3PH can be filled with grasshopper vomit, but should be covered.

Best, Bill

Liquid in the tires most certainly is ballast. The point of rotation is the front axle and the "moment' is the weight of the fluid times the distance from the front axle . Weight on the three point hitch is more effective then fluid in the tires because the distance is greater. Put a 1000 pounds of fluid in a set of rear tires that are seven feet from the front axle and they will give you 7000 ft lbs of force. Move that same 1000 pounds out to the ends of the 3PH at 2.5 feet behind the rear axle and you get 9500 ft. lbs of force.

I will regret this, so here goes:

Call filled tires whatever you want. Filling tires increases available tractive force, lowers CG and helps a bit keeping rears on the ground for loader work.

However, filled tires do NOTHING to reduce front axle load.

Grasshopper vomit. Now that's funny right there

Agreed. I was only considering keeping the tractor with all four wheels on the ground not the load on the front axle. But say that the load in the bucket is ten feet in front of the rear axle and a 1000 lb ballast box was three feet back of the axle. The 1000 pounds would only reduce the load on the front axle 300 pounds right?
