Hub Centric vs Lug Centric

Are my OEM ENVY Wheels (20x8 ET24) on my 2013 R/T Classic Hub centric mount or lug centric mount. You know, I've rotated these wheels twice a year for 5 years, and just did it a couple weeks ago, but I cannot recall if they center over the hub or not.

The reason I'm asking is the aftermarket wheels I'm looking at come with a slightly larger hub bore (74.1mm vs. my stock wheel is 71.5mm). I realize that if necessary, the new wheels will come with a hub ring to make up the difference, however, the lugs patterns is also 5x114.3 while my OEM wheels are 5x115. I'm hip to the insignificance in the bolt pattern (alone) but am I asking for trouble by having both the center bore and bolt pattern being slightly off? If hub centric, the ring should center it and the bolt pattern issue becomes a non-issue. But if it's centered by the lugs, will the different bolt pattern make my wheels not necessarily centered?

IIRC, our stock wheels are hub centric.

That's what I expect, but I'll be damned if I can recollect it myself (Getting old sucks). And with the little chrome center cap on my wheels, It's some thing I can't see when I slide them on.

Yes they're hub centric.

All OEM wheels been hub-centric a long time for safety, maybe gotta go back to left handed lug nuts to find a lug-centric wheel.

Thanks, man. It's something I assumed, but also something I just haven't given much thought to.

You can run that 114.3 bolt pattern without issue.I run that pattern and a lot of people I know also run it with drag radials.The difference equates to the thickness of six sheets of paper so it is a sheet of paper thickness at each stud/lugnut off.

Keep in mind that 5x114.3mm, which is also 5x4.5", is not the same as 5x115. You would need a hub centric wheel adapter and you would have to find someone like US Wheel Adapters to custom build them. I suggest looking for wheels with a 5x115 bolt pattern.

.7 / 25.4 = .02755 inch. More than I'd like personally.

That .7 is the overall difference. We are talking about the diameter of a circle drawn through the center of the bolt holes that is .7 mm different. If you buy pencil lead for a mechanical pencil a common lead size is .7mm. The radius of the circle, or the amount the distance that each stud is off is .35mm. The smallest pencil lead I have seen is .5mm so your talking less than the thickness of the smallest pencil lead available. Or since I'm old school and think in inches here is another comparison. 1/64 of an inch = 0.0156" = 0.3969 mm. We are talking less than 1/64th of an inch, I seriously doubt that tolerances of mass produced wheels are that tight.

People have been running 114.3 wheels on 115 bolt patterns for years, and lugs haven't snapped and wheels haven't flown off. If they had, aftermarket wheel makers would not guarantee fit for 114.3 wheels on cars with 115 lugs or the lawyers would have sued them out of business.
