the bolt pattern means 6 lugs that are 5.5" apart, centre to centre.
the hub ring is the size of the hole in the middle of the wheel.78mm/3.07"
the off set means from dead centre. 22mm/0.87" towards the out side of the wheel, is where it is mounted.
the 22mm oem hex means it uses a 22mm socket.
and the 14mmx1.5 is just the thread type of the bolt.
i hope this helps explain everything.
