Apples and oranges (cliché, I know.)
The figures are copy/paste right out of the factory service manual.
Most runout numbers are measured at the tire tread. The figures posted are at the wheel, which are closer to the center. Therefore the numbers will be smaller than most people are used to seeing.

The figures assume in-service inspection.
It tells the mechanic to remove the tire, and mount the wheel on a dynamic balance machine to measure wheel radial runout, and lateral runout.

I agree.. and I can't help but wonder if they were snugged down to the hubs incorrectly. (IE, not securing the lug nuts in a star pattern).

Was the JK in question wheeled hard?? Or do the wheels have some bad curb rash?

Nope never wheeled it hard just minor trails and never hit a curb ?!?! And I try to avoid potholes ! Lmao best bet is to have good year take a look at it tomorrow ? Do the tires have to be off the rims when they check the rim to see if it's bent ? I want this done right tomorrow when I go there ! Thanks for the help guys

Good year told me they could only balance one tire perfectly the other tires where taking over 17 oz to balance them , they said the rims were not bent , the problem is the tires are "cupping"

Cupping is caused when tires are driven on and either not balanced or not balanced properly

No way to fix to my knowledge, also bad wheel bearings could cause cupping but it is doubtful in you're case all the wheel bearings would be bad. most likely they were not balance correctly from the beginning.
