I just checked the manufactures web site and I can't find if it says they are hub centric or not. Not sure if it makes a difference but they are factory replica wheels.
I don't actually have the factory lug nuts because when we purchased the car it already had aftermarket wheels.
I'm wondering if I didn't have them torqued enough, I say that because after thinking about it I had to use every once of force I had to get them loose. And I broke a socket adapter clean off my impact driver while trying to loosen them on the first one.
Overtorquing the lug nuts is not a good idea either.
Tighten them to factory specs, if they won't hold try a set of oem or gorilla lug nuts.
It's worrisome that they were that tight when you took them off ... I hope the previous owner didn't damage the bolts by overtorquing them which has led to the current issue.
