I want to change my 1200 from having bolts that hold the wheels on to studs. Can I just get the appropriate size bolt (7/16-20x1.5) run them in from the back them get automotive lug nuts to use ? I did notice that all the factory bolts are is grade5,I don't see why I would need grd8. What have other people done? Changing tires without having studs is a giant pain in the butt!
