Need some help determining wheels and tires
 

I've dug through about 8 pages of threads here, and I'm not finding what info I need.

I'm going for a specific look for my 98 Blazer 4 door.

I want to have a flush fitment, maybe 1" of poke on all four corners without the use of spacers.

I would like to stick to 15's and have a taller sidewall, what backspacing/offset wheels and width should I be looking for to achieve this look? As well, what tire spec would be best?

I'll also be dropping the suspensions slightly so that there is maybe 1/2" between the bottom of the wheel arch and the top of the tire.

2wd or 4x4? as that makes a BIG difference (different track width and offset by about 2" between 2wd and 4x4)
