John, etal.
Center Locks / Split Rims / (so called) Safety Rims. They are all
dangerous
unless properly installed. I have done quite a few of them. In the absense
of
a cage we lowerd a car hoist down on top of the tire and put air in from a
remote control. We used the hoist as a couple of tons of safety. Even so it
is and was possible to end up with a dandy sky light. A heave ring propelled
by 40-60 or worse 80lbs of pressure is a dandy missle. I am a bit amused how
you handled the safety issue. You said "laid them flat in the center of the
back
parking lot, then aired them up while peeking around the corner of the
building."
I think this shows that you too have a healthy concern for the
possibilities. Did
you ever loose a ring and see how high it went? By the way John, that was a
really good description of some of the more common reasons for problems.
My comments were and will always be to get people to have these rims
done the right way by people with the proper equipment and education. I
agree that many of these are in use and most of the problems are due to
improper seating of the ring. Wether it is rust or ignorance of how to seat
the
ring it is still a dangerous situation and I wouldn't want anyone to pay the
price.
Its too high. If you want to use them get experienced help.
Hey these retainer rims in several forms are on so many BIG rigs that
there
must be something good about them and there is. How about changing a tire
on a BIG rig in the middle of nowhere with no help. Yep. It can be done and
I for one could do it if really necessary, though I wouldn't like it. With
almost
anyother wheel design you would never even get the bead broken.
I see a place for these rims and if you are going for an authentic
restoration
you would need them on some models. If you are on a big rig you can and most
likely will use them. If you want to do them yourself get some help and
instruction.
If you don't know how to do them go to a tire store or truck stop that knows
what to do. ('Taint that expensive and its a LOT safer.)
