I have just purchased a set of 2 inch dropped spindles from western chassis. Before I install I want to determine wheel width and tire size for my 82 malibu wagon. I am currently running 225 60 15 on 8 inch rally wheels. If I go to a seven inch wheel with this tire size will I have a rubbing issue. If so what tires size would I need to run to avoid that on a 7 inch wheel.
