My '98 XLT 4x4 came with the stock steel 16" wheels and when I did the 3" lift they looked small to me. So I found a nice set of 17" Ford OEM slotted alloys for $200 which came on the 'OffRoad Package' trucks and they look a lot better.
Mounted a set of 255/75s instead of the more common 265/70s, they might look good on your 2WD. in my experience taller skinnier tires work better in mud. I had to order them but it was worth it.
