1965 Dodge Dart Charger
Kevin! I can't get what you mean. School me please! :coffee2:
I caught Dan's ??? on this too. I was never able to get an explanation from anyone as to why this was the case, but wheels with .000" runout at the rim were considered scrap. I believe it had something to do with the runout of the tires and matching the high spot of one to the low area of the other and vice versa. Lateral and radial runout are measured on the wheels and it's the radial runout that's the more important of the two.
If you read through Section 22 of a service manual there should be a section on Tire & Wheel Runout.
Matching of wheel and tire high and low spots has now become an automated process at assembly plants. If you look at any brand new car, particularly before it has been pre-serviced, you'll see a little sticker on the wheel at the rim and another near the bead on the tire. These two stickers indicate where the tire should be mounted on the rim for minimum radial runout at the tread face.
From what I'm told, it was actually fairly easy in the wheel plant to get a rim to have .000 runout, and that was usually the initiation of any new foreman assigned to that portion of the plant.
