looking for knowledge about wheel spacers on a 4x4- good idea? have a set of 16" wheels to go on my 91 Suburban (oobs), American Racing Baja's- #883. anyway, they bolt on but touch the tie rod (guess the BS is barely too much). factory wheels(15") seem to have 1/2 inch clearance in this spot. they don't hit til i tighten lug nuts down, so it's just barely touching. so, i was thinking a 1/2 inch wheel spacer would allow these wheels to work. i guess i would need to put them on all four corners, not just the front (back wheels bolt up fine). any problems with using wheel spacers? don't do any wheeling really, daily driver. are wheel spacers safe? good places to get them?
