New wheels?

im thinking about turning my 2002 ford explorer XLT into a show car, but still use it as a daily driver. i was wondering if i get 20" or 22" wheels, would i have to cut into the wheel wells for clearence? or would i be okay?
Im also thinking about lowering it about 2-2.5" and am wondering about the clearence as well.
thanks everyone!
