Hubcentric spacers center bore/hub diameter

[mindbomb]

I am getting hubcentric 1.5" wheel spacers for my KJ.
What's the center bore/hub diameter spec I need?

Wheels are stock 6 spoke.

I found on the web both 71.5mm and 67.1mm, which is correct?

Could of sworn I just answered this question
71.5

Should wheels conform to that specification? I haven't seen any wheels that mention the bore hole size, or the stud size, for that matter. My shopping has concentrated on wheel diameter (16" preferably, or 17"), width (7 preferably, or 8") and bolt pattern (5x4.5" or 114.3mm). Is a 71.5mm hub pretty standard for wheels? Or is this just a concern if buying spacers/adapters?

I have a '95 Silverado with aftermarket wheels. The wheel hub bore is larger than hub on the truck. Have had no problems.

Had a '01 Ram with aftermarket wheels. Same thing, no problems. Both these trucks were/are for work and haul 1500-2000 pounds daily.

Also have a '14 Maxima with aftermarket wheels. Same deal. Wheel bore larger than hub. But, these wheels came with hub adapters that take up the space between the wheel hub and car hub. But, again, no problems.

Have also had a '82 ElCamino, '79 Chevy 1500, '83 Camaro, '91 Integra, '89 240SX, '93 Accord, and who knows what else that all had aftermarket wheels that had a larger wheel bore than the car/truck. And again, no problems.

BUT, if using spacers, I personally, would use stock wheels with the correct bore, or aftermarket with the adapters.

Reason being, spacers are aluminum and the hub is steel. Therefore, in my thinking, the steel hub where the lugs are "mounted" would be stronger than the aluminum on the spacers and handle the weight and forces better.

Soft 8s and other aftermarket wheels are all bigger ( center bore)
Have ran wheels like that on various builds for over 40 years with no long term effects

Yar. Wheels are stud centric. As long as the hub fits through the hole in the middle you are fine. Any half decent wheel spacer will be hub centric so specific hub size is nessecary spec. Based solely on my own observation however I'm pretty confident this is accurate

It's just how the part (wheel or spacer) is centered on the axle. By the studs or by the hub
