I noticed the same issue on my OEM 19's, which I unfortunately do not have any tires for. The Apex setup has been road force balanced, and has runout measurements well within spec. They are also completely hub centric and I am not using any spacers.
If you're willing to let me borrow yours I'd be in your debt and will do what I need to make it as convenient as possible for you.
