a few of those holes/slots look a little oblong- good luck getting them to stay centered on the hub if they aren't hub centric and you don't use centering rings.. you will probably have one wheel that will never stay centered, and you will get a weird and really annoying pulsation that comes and goes at weird frequencies and at different road speeds..
also, the lugs will come loose after you first put them on, then they will stay tight for a while after you tighten them a few times... then one day out of nowhere you will feel a weird vibration and find a wheel ready to fall off and those hogged out lug holes will be just a little more hogged out...
yeah, i've had a few old worn out aluminum unilug wheels in my day...
