Tires Tire/rim tear down

[wmonroe]

I only use the old 961 about 10-12 hours a year doing some brush hogging and general work.
One thing I've wanted to do since I bought the tractor about 7 years ago was to get the calcium out of the tires. I had it out brush hogging the other day and saw the valve stem looked damp on one of the tires and I knew it was time. Funny thing is, I just put new cores in the valve stems about 8 months ago.
So today I drained the calcium out, pulled the inner tube, and then popped the tire off so I could clean and repaint the rim. The rim had some rust but luckily all solid metal everywhere. The rust was the worst around the valve stem. Tomorrow I'll get the rim cleaned up and a good coat of primer on it and maybe a coat of paint.

In my area owners are using windshield washer antifreeze instead of calcium or the beet juice stuff.
It is not the heaviest liquid but for a cost that is more affordable and does not damage the rim.
Most of the time it is being used on tubeless tires as further evidence of its lack of corrosive damage.

Windshield washer fluid is what I put in my kubota. I have about 30 gallons left so that will be a good start for what I need for the Ford. I think each tire will take about 43 gallons. I would like the extra weight of beer juice or calcium but I'm not willing to deal with the corrosion of calcium or the price of beer juice. My plan is to add wheel weights to make up the difference and some extra.

I highly recommend using rust converter AFTER you clean as much off as possible. Rustolum and similar primers are not intended to remedy rust that bad. The best converter I've found is Jasco but there's others.

I was able to get 99% of the rust off with a few different shape/size wire wheels and cups on my angle grinder. It actually cleaned up very nice but I forgot to get a picture before priming. After grinding I washed the entire rim with a detergent solution and once it dried in the sun rinsed and wiped it all down with brake cleaner. Sprayed one coat so far of rust converting primer, can't remember the brand right now but I've used it previously and it has worked very well. Probably going to do two coats of primer, one coat of paint, and a coat of rubberized undercoating. Mainly using the undercoating to fill in the small pitting and because I've had it laying around so might as well use it up.

The BEST fix for those rims is complete sandblasting, and two (or more) coats of marine 2 part epoxy paint.
