Hub Centric Spacers 1989 V1500

I see a lot of chatter about wheel spacers for offset but nothing significant on hub centric. I'm planning to use a 17" late model factory chevy wheel on the suburban. Best I can tell the Mile Marker hub o.d. is 89mm, the wheel i.d. is 108mm. I can find the 108 dimension on a ring, but the largest I see to fit the hub is 87. I feel like I'm measuring 89 but that's half ass without the wheel off. Essentially calipered the i.d. of the cap. See photos.
Mile Marker is closed for the day and their data doesn't indicate hub o.d.
Is it 87, or is it 89mm? (photos are used to indicate measurement for either hub or wheel)

That wheel you have pictured is aftermarket. There's been a bazillion 6-lug trucks run with aftermarket wheels and no hub-centric ring. It'll be fine.

However, you MUST make sure your wheel studs are long enough for good thread engagement with those wheels.

Interesting. I can picture the wheel sitting flush and universally across all lugs once the lugnuts tighten. I picked up some 87mm rings, let's see how that works. A nod to the length of the lugnnut, I should be good with these. Thanks!
