58 Apache rim and hubcap help needed

[Foot Stomper]

Here's what I learned recently while fitting my 59.
In 56 thru 59 GM offered 15" and 16" rims. Not split. They had three hubcap clips, 5" bead width and no lobes. See picture below of the yellow rim...this is what you want.

They are different from 55 and earlier for two reasons...you can tell by the 6 hubcap clips and they are a 4.5" bead width. See picture below of ugly green rim that you don't want!

Now comes the arguable point. Because these earlier rims required tubes some folks will say you have to because if you don't, a modern day radial will not hold the bead for lack of the "safety bead" which is a very low profile lobe that runs on the inside of the rim parallel to the bead....just far enough to hold the bead of the tire. Failing to run a tube may cause the bead to break on a hard turn... they claim. Others will claim that for many years they've run radials without tubes and never had a problem.

I've decided to run the 16" x 5" three clips to accommodate the dog dish caps. I've also purchased the Coker Classic radials that look like a bias ply tire and they advise running a tube...so I will.
