Measuring Your Wheel's Bolt Pattern
A "bolt pattern" is essentially the diameter of the "bolt circle". Basically, the bolt pattern of a wheel is the diameter of the circle that the bolt holes are drilled on.
If you were to draw a circle through all of the lug holes in your wheel, the diameter of that circle, is your bolt pattern.
