The lib steel wheels are probably the most common Jeep 16" wheel in the 5x4.5 pattern, and arguably the ugliest. You could probably score a set of those for less than the cost of even used spacers- if you aren't in a hurry, you could probably even get alloys that cheap. I saw a set of the Icons, painted black, selling for $80 on another forum. I paid 200 for my set, but I was sick of steel wheels.
Is the Jeep lifted? 245/75s on 16x7 wheels is a lot of tire compared to the stock setup. It's a little snug at 2" even, but aside from rubbing the LCA at full lock, isn't bad. No flare-related violence or strange noises otherwise.
