Fluid In Tires Question

bowhunternw · Sep 2, 2017

So I picked up a 300 utility tractor earlier this summer, it does have fluid in the back tires. What I am wondering is, is it always in tubes and does it cause rust on the inside of the rims? I have some surface rust on the outside of the rim that I figured I could clean up and paint. Just hope there isn't damage happening inside.

I had gotten rid of all the calcium chloride in tires here, until this spring, when I bought a tractor with fully loaded tires. Like yours, there was some surface rust. Not bad. I cleaned them up and painted them. I also replaced both air/water valve assemblies. I wasn't sure I was going to get them out without breaking something, but I did. I will deal with whatever is going inside if and when I have to do tire work.

If you have a serious problem, it's very obvious. Usually bad/deep rust around the valve stem. You most likely have inner tubes. You can tell by looking closely at the stems.

What would be different about the stems?

The worst thing is fluid filled tires that have tubes in them. The tube leaks an then fluid gets between the tube and rim. This will rust them out fast. I have some tractors with fluid in them. I have them all mounted tubeless. Then fill the tire up over the rim with fluid. Without oxygen the fluid will not rust the rims. One JD 4020 I have has had the tires loaded for 35 years on tubeless tires/rims. Just replaced the tires this last year. The rims where in perfect shape inside. The area outside of the water valve/stem had some surface rust but nothing else.

So on an older tractor that you need the weight of the fluid on I would take the tubes out and mount them tubeless. You will have much less rust troubles.

So is it something I should try to take care of, or is it something where I should just worry about the exterior?
