f-20 rear wheels

I recently had a flat on the rear wheel of my f-20. They are the cast wheels and the tires were living on borrowed time. The tire store where I had the tire dismounted and discarded did not have a problem dismounting it but are hesitant to mount a new one on it because it is a split rim. Does anybody make a regular rim with eight drive lugs that will bolt up to my IH cast wheels?
 
If (and only if) the rim and removable parts are in good condition, meaning no rusted places with pits, bent or deformed components, or welded/modified. would I consider them usable.
However!!!! the basic idea of horror should be in consideration of the fact that split rim failure with catastrophe is usually associated with high pressure truck rims (100psi or more) not 15 PSI tractor tires.
If things look good, have them put in just enough air to shape the tire. then with it outside facing a clear area, inflate to 12PSI using a clip on hose and a valve to control it. This reduces danger to Near Zero. Run it at 12 for a while and adjust as needed. Jim
 
If old rims are un saveable, miller tire might have some. I tend to agree with the other post: 12 or 15 psi, at the low mph of a tractor, and a little caution/ precaution and common sense and the old rims should be fine.
 
I have the same pair on my F20, spit rims. I had them blasted, and then I primed and painted them. Put the tires back on and it is fine. Split rims, when properly mounted, are safe.

The horror stories you hear about split rims are either A.) someone did NOT pay attention and follow proper safe installation. B.) The rim was in poor, deteriorated condition. C.) Over inflation, which, BTW, is equally dangerous in a solid rim as well.

If your tire place is reputable, AND handles split rims, have them evaluate their condition. If serviceable, use them.
 
I have a couple sets of those and I like them. Unless they are really rusted, they are not unsafe in my mind. If you look at them, they are designed so that as the tire inflates the ring is compressed smaller and smaller, making it less likely to pop off, as long as it is not compromised by corrosion use it. They are a heck of a lot easier to mount and dismount tires on. As for other rims, the 38 inch rims used on CO OPs and others like Oliver maybe, should work, they have 8 lugs spaced the same. You can also use drop center 38 inch rims from H and M Farmalls and some s also, just need some more rim clamps.
 
I have heard of people bolting H or M rims on the F-20 Cast Iron centers. That may solve your problem.

Search the archives.
 
If you are not wanting to mount them yourself call around to the different ag tire dealers in your area. I would bet one of them will have someone with some knowledge under his belt that will do it.
 
I complete agree. As far as I'm concerned, they are really easy to mount tires on. I have had mine on and off a couple times and never had an issue.
 
also as you are inflating the tire, just put enough air in it that it starts to push against the lock ring, then go around the ring and tap it in towards the rim, put a couple more pounds in and repeat, once the ends of the lock ring meet it is fully latched in the groove, and you can inflate to whatever you need it to be, usually 12 to 15 psi. I usually run 12-13 psi.
 
which is the exact same kind as mine. I'll post a picture later today of the restored rim/wheel.

Take a close up of the ring locking portion and the rim locking portion and post here. I'll give you my opinion on whether or not it is salvagable. Or, send me the pics, and I'll post.

all of them I have seen the ring was split, not a solid ring. I would like to see a pic of that rim also. I have 3 sets and they are all alike.
 
on mine, the rim is split, but the lock ring is solid. I'll try to get some pics after dinner tonight, Will be hard to see that the ring is solid, but I'll try.
 
Well, I saw the pictures of the rims, and chatted with B. Williams. The rims are in VERY good condition and VERY usable. If anyone is interested, I'll post a couple of the pics.
 
I would be interested in seeing the photos, there seems to be a LOT of mis-information about these rims, a picture is worth a thousand words.

Rob, my 1949 IHC KB5 has split rims too. 6 wheels, 2 were solid lock rings and 4 were split. Both my rear wheels for the F20 with the cast center are solid.

Would be interesting to do a little research on the logic between a split lock ring and the solid ones. Also, when were they used, etc.
