I'd recommend a swipe of anti-sieze on them...
The hub-centric aluminum wheels on my Pathfinder required significant persuasion to come off the steel hubs on the rear.
As in, 5-lb hammer with 36" handle.
After cleaning up both surfaces and applying anti-sieze, it's much easier now.
anti-seize is ALWAYS required on dis-similar metals and stainless fasteners.
a tip for removing stuck alloy wheels. if on the front, loosen all the nuts, then snug 'em up, back off two threads. crank the steering wheel back and forth violently until you hear a pop or a loud crack. the wheel will be now loose, and without damage. if on the rear, loosen the nuts as before, then drive in a tight circle [at a slow speed] and slam on the brakes. repeat until you hear a pop or crack. the wheel will be loose now.
sure "beats" wailing on the tire or rim with a sledge hammer !
make sure to thoroughly clean the hub register and wheel center, then apply anti-seize before installation.
