We all can talk about the rings and other parts of the wheel and their
condition. In many cases we are talking about parts that are 50+ years old.
They WILL have rust on them and the locking surfaces will be not 100%.
Understand that there are different types of 'split rims'.
The ones on the WW2 CCKW and Chevrolet trucks do not have a split in them. The
ring is streched over the hub of the wheel. The ring does not go under the bead
of the tire.
The ones on the M37 do have a split and the split ring is under the bead of the
tire.
Some civilian trucks have 3 piece wheels: The wheel, a solid ring and a split
lock that is about 3/8" square that fits between the other two pieces
Some trucks in the 50's-60's had wheels that came apart in the middle. You can
tell these because they have a large raise area in the middle of the wheel. I
believe that these are outlawed now. Many places will not touch them.
When thinking about what will happen if/when something goes wrong, remember
that the forces inside that tire trying to get off are increadible! I
personally do not use chains because if they fail during a failure of the ring,
they may be more dangerous that the ring. I usually put a little air in as
explained in an earlier note and tap the ring and look to make sure it is
seated evenly. I then mount the wheel on a truck, ring in, and finish inflating
it. If you put the wheel on the ground and put a vehicle over it, you will
seriously damage the vehicle if the ring lets go.
