Title: Original Magnum 500s or Magnum no hundreds?
Post by: deathsled on October 15, 2023, 01:29:12 PM
On a cleaning binge. Found these that came off of his 66 fastback.

Just from the pics they APPEAR to be Mopar rims with the greater negative offset when compared to Hertz Shelby rims.

So in other words, worthless. Thank you for your input.

I did some rudimentary measurements. To begin it looks like these are 15 inch rims.  Aren't originals supposed to be 14 inch? Besides, even if they were original they look like garbage. I put them out by the side of the road to see if someone wants them.

Look at the tire size on the tire itself.  There will be your answer.  Hertz Magnums are 14".  I'm sure that when cleaned up they will look much better.  Nice chrome Magnums can bring a few bucks.

The measurement on the rim is 15. The tire size says 14.

Measure the rims from bead to bead, not from outside edges.  They look like 14's to me.

I pulled them from the side of the road to further evaluate.

Tire says 14 then a 14" rim. It is weird how they are measured in size.

Same with wheel width as that is measured from where the tire bead seats on each side.  Many people still measure from outer edge to outer edge.  There's usually about a 1" difference.

So factory wheels like Magnums and KH steel wheels have the width stamped in the rim like this 68 Shelby steel wheel(6 inch)  12 29 date and "6" next to 29 right of valve stem. Chrome Magnums on the back side (7.0)

They are stamped though location of that stamping and other codes depends on year they were made (both Motorwheels - Magnums and KH). Some are visible while other years are not once the tire is installed. Examples of those have been posted in a number of prior threads

Thanks Jeff. I didn't want to go into depth on that like the 69 Shelby wheels are stamped on the rim so with the tire on cannot be seen. I posted pics of some known original rims like the Magnum pic is the original rim on a 69 Boss 429 to be clear.
