I am looking for some inexpensive black steel wheels. 15x8, 6 on 5-5, 3.5 to 3.75 backspacing. Where have you guys/gals found em?

Summitracing.com

thanks, I had forgotten about Summit.

definitely summit, i think they're around $40 for the black steelies.

if you have a offroading magazine look in there. If you dont go to the grocerie store and start reading them lol. I just picked up an issue of Petersens off the stack in my closet and www.desertrat.com seems to have some wheels for as cheap as $44 bucks a piece. The phone number there is 1-800-528-3402

If you want super cheap, just go to your local junkyard get a set and paint 'em up. I got a set of the wagon wheels or whatever they call them for about ~25 and that's including the paint.
They're gonna get torn to chit anyway
