4.5\" Backspacing for 1975 Blazer I am close to purchasing wheels for my 1975 blazer and am interested in Rock Crawlers. I'm not sure what Backspacing is, but I was told I need 4.5" backspacing for my rig. Does anyone have Rock Crawlers with 4.5" backspacing installed on a Blazer and do you have pictures? Second question - is 8" width a good choice for Rock Crawlers on a blazer? I plan on installing 33" tires. Any help would be appreciated.
