Full-sized Broncos & F150s (and a few F100s) through the 1996 model year all have the same 5x5.5" bolt pattern and can be used on the Sportage. There may be other vehicles (Dodge trucks?) that have similar bolt patterns. I know that Chevy/GMC use a 6-lug rim, so they will not work on the KIA.

Try a search for "tire size" in this forum for all kinds of info on what fits, how much and where rubbing occurs. I believe that a 235/75R15 will fit a non-lifted Sportage with minimal rubbing under compression and possibly full-lock turns. This size will also fit on the stock rims. Not sure if the 2WD Sportages have different clearances (I doubt it), but you may want to go to the local tire shop and ask if they'll test fit some to be sure.

IMO, the Eibach lift and 235 tires are perfect. Only rubbing I have is a slight contact with the left rear shock. Not enough to scuff the tire, but the paint is worn off the shock.
