All good stuff but don't forget the other important factors...
Firstly:
The list shows all the 4 x 100mm stud pattern but doesn't show the offset. Offset is important if you don't want disk callipers grinding against rims or tyres scrubbing on panels.
Secondly:
The centre of the wheel has a large round hole in it. This hole is where the wheel hub bearing housing snugly fits into. It is important that the wheel matches this hole size. The centre hole is what lines the wheel up. The wheel studs only hold it tightly to the hub. They don't centre the wheel! Chances are great to have a wheel suddenly tear off if you push it too far at high speed. Hitting a big bump or pothole can shear the wheel studs if they are centreing the wheel alone. You might be able to use a wheel with a larger centre hole if you have a spiggot made to locate the wheel. Check first as it may not be legal in some states. _________________ I try to tackle one day at a time, but often several days attack me at once.

Ok I plucked this info from a web page... it gives a good description of offset and how it is measured.
Wheel Offset, Rear Spacing and Wheel Measurement
Rear spacing (or backspacing) is the distance between the wheel's inboard edge and its mounting pad. It can be measured by using a ruler and a straightedge set across the backside rim of the wheel.
Offset is the distance from the wheel center to its mounting surface. To find offset, plug the rear wheel spacing and width into this formula:
Offset = Rear Spacing — Total Wheel Width
2
If you have a "positive" offset, the mounting pad is in front (or outboard) of the rim centerline. This situation most commonly occurs on front-wheel-drive applications. To picture this more accurately, think of the convex design of many wheels found on front-drivers; the center of the wheel sticks out further than the edges of the wheel. If there's a "negative" offset, the mounting pad is behind (or inboard of) the rim centerline. This is typical for most standard rear-wheel-drive vehicles and "reversed" rims. Sometimes, this style is referred to as a "deep-dish" wheel.
For example, an 8-inch wide, 3-inch-rear spacing wheel would have a 1-inch negative offset. Conversely, if the same 8-inch wheel had a 5-inch rear spacing, it would then have a 1-inch positive offset. Finally, if the same wheel had a 4-inch rear spacing (which is exactly half its width) then the wheel would have what's known as a "zero offset." _________________ I try to tackle one day at a time, but often several days attack me at once.
