Wheel upgrade question (newbie-ish)

This is a rather newbie question, but do I need to modify the suspension system if I upgrade wheels say from 16" to 17" or 18":. What if I wanted to go higher than 18", say 22" spinners? Just kidding about the spinners. Thanks in advance.

If you dont care about performance (and with 22" I dont think you do then you don't need to modify the suspension
But generally, the heavier the wheel you are wearing, you will need a suspension setup with more rebound to compensate for the increased unsprung mass
