Can anyone explain wheels/sizes to me?

I don't entirely understand.
For example, if I were to buy this (I'm not) how would I know if they fit or not?

The first thing to check is the bolt pattern, 5x108mm(5x4.25") is the SHO bolt pattern. The problem with that is that there are very few cars that use this bolt pattern. Volvos are the most common, along with T-birds and Ferraris.
#2 is offset, which depends on the width and diameter of the wheel.

Both bolt pattern and offset can be changed, but its not always the best/easiest/cost effective thing to do.

Those RX7 wheels wouldn't fit without drilling a new bolt pattern, and possibly changing the offset.

Searching for wheels on ebay... searching by bolt pattern will find the wheels that will have the best shot at fitting.

You also may or may not want to consider center bore diameter. For example, a wheel for a Volvo has a larger center hole than one for a Taurus. Used on a Taurus, a Volvo wheel will not be "hub-centric", but I have not had an issues to date with my particular wheels on my car.

tire rack has some decent wheels on it (click on link from the forum homepage, as it gets a percentage of purchases). you can check the classifieds, as some show up there on occassion. or, as said, try ebay, but remember bolt pattern and offset. searching for taurus and tbird wheels on ebay will probably get you a bunch of selection.
