If 4WD, load all four tires with calcium chloride solution. If I were loading tires on a tractor for the first time, I think I would pay extra to be sure they had tubes in them, on the assumption that the rims would last longer this way. I will be getting a new set of rear rims on a couple of loaded tire tractors without tubes some ("Surprise!") time in the future and am not looking forward to it.
I really agree on getting tubes in tires. However, even if you do, I'd suggest using something other than calcium chloride. It is quite corrosive. I've got
RimGuard in mine. It is made from beets. In my last tractor, the tires were filled with automotive window washer cleaner (winter version). Some people use RV/Boat antifreeze -- don't use automotive anti-freeze (ethylene glycol) in case you puncture a tire. It can poison a well, or your animals. Some dealers also have some safe propylene glycol mixes.
