your wheels inherently have backspacing. you need to figure that out to make sure the wheels are appropriate for the tires.
but assuming that's not the issue, it sounds like something is bent/broken/missing. either the rear track bar itself is broken (or missing), or the bracket has ripped off the axle. if the bracket has ripped off the axle, it usually takes the upper control arm mount with it. if the rear track bar has been removed, then some moron has ruined your tires due to ignorance of basic geometry.
crawl under there, take some pictures and post them up, so we can help. or just crawl under there and figure out what the problem is yourself and fix it.
