Different styles of "Budd" disc wheels

Wow, this forum is really educational.  All these years I wondered why those truck wheels had holes. For brake drum cooling maybe? No, those are hand holes.   Now it all make sense. Thanks Tommy!

Your actually quite right Peter! We tend to generalize a lot on terminology, they are ventilation holes, but we like to take short cuts and call them hand holes because it is quicker. The air valve stems are centered in the ventilation holes and you must put your hand thru the ventilation hole to air up the inner dual.
