says it adds 4″ per side but confused mostly because that picture showing the measurement of front and back where measure line stops mid wheel where the hub would be and says 72″. so is it 72″ from hub to hub meaning with stock rear wheels offset 6+2 the total width is 76″ or do they meany 72″ from outside wheel lip to outside wheel lip (stocks) and the picture is just wrong? This is important to me as my trailer is only 74″ wide.
