Spent some hours over the past days removing the 50 year old tyres from the combat divided rims. Some swearing ensued ! Hydraulic jack and levers , lubrication and much physical persuasion - all needed.
Jeep owners: please install the rust bands for future problems will arise. The divided combat rims do rust to the stage of being U/S. The original rims are now around 80 years old.
Repro rims are now available , but they are not cheap ( $1500 for a set here ) and there have been reports of a particular brand actually failing
In my case , I have four useable rims and one only good for a spare. The four best have rust to varying degrees but IMHO are safe enough. But I have to check them for runout and balance.
Looking at this G503 video shows how the rims rust but are still serviceable.

The other very common problem : people overtighten the lug nuts, doing this damages the tapered holes in the rims, the hole is splayed out into a distorted oversized shape and this results in the situation where the lug nuts do not have enough grab effect, the rim can be slightly loose on the hub......have seen this problem myself.
