What does 5 x 4.5 bolt pattern mean?

"The bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns can be 4, 5, 6, or 8 lug holes. A bolt circle of 4x100 would indicate a 4 lug pattern on a circle with a diameter of 100mm." 5 x 4.50 converts to 5 x 114.3 (mm). http://www.tirerack.com/wheels/tech/techpage.jsp?techid=92
