Another tire loading question...

How does that work with tubes though? Can you adjust air pressure with them?

Yes. Same way

Yeah, filling tires does nothing for the actual tire pressure. Once filled, you must then top up with compressed air to the desired PSI.

Just to be sure you understand, when you "fill" tires with liquid ballast, you don't actually fill completely. That is, traditionally they are filled about 75%, though many others say they only fill 50%. There is air space, so if you rotate tire so valve stem is at the top where the air is, you can remove some air if you want. Or add some, of course...

If you have any trouble with the tires spinning, filling really helps.
MY guess the reason tubes are recommended for Rim Guard is it may be slippery enough to cause the tire to slip on the rim at low inflation.

Maybe I missed something. Who recommends tubes for RimGuard? It's Calcium Chloride that should be tubed !!

I have three tractors right now and all are filled ~70% with Rimguard without tubes. I've also had a few tractors previously with Rimguard and they did not have tubes. That's just the way it's done around here and I've never had a problem. Also, if you should get a puncture from a thorn or nail which I've had you can fix it very easily with a plug without removing the wheel from the tractor -- big plus considering how heavy loaded tires can be.

Per rimguard slip issues:

One guy who neglected to air up his tires after installing RimGuard does not make an issue. You put the valve stem at the 12 o'clock position, fill the tire till it won't take any more. This puts you in the neighborhood of a 70% fill. Replace the valve stem, and add air to the manufacturer recommended pressure. No slippage.

The local rim guard installer was who recommend the tubes for filled tires, be it rim guard or calcium. I didn't question the issue and he seemed to imply that any filled tires should have tubes installed.
