I've searched the forum and google already, so...

I just mounted my tires tonight, and plan to mount them on the car tomorrow (both about 30 mins away from me), but i'm not really sure what kind of lugnuts should I use?!?
I picked up some acorn shaped lugs tonight on the way home, kinda like these ->http://www.gorilla-auto.com/products...image=4920.jpg

Close ended, 12X1.5 thread pitch. Are these going to work?
I just need to use them until I can get a set of locking lugs.
Thanks.
