This boggles my mind. I've never seen a car without wheel studs on the hubs. The only reason to do it with holes instead is to make you go to the dealership. Lame.Most older cars had threaded lugs sticking out from the hub so all you had to do was lift the tire and throw it on the lugs and they would hold it there so all you had to do was put on the nuts.
My Jeep and I assume many cars now don't use that simple system, There are no threaded lugs sticking out so you have to hold up the tire, There are only holes in the hub so you have lay on the street so you can line up the holes while you are holding the tire because there is nothing to hold the tire up so you can line it up to start the lug .
However that does make me think you should be able to convert them back to normal by screwing studs through the back of the holes like usual.
