The proper way is to remove the tire and wheel assembly from the vehicle, remove the valve core from the valve stem, position the bead breaking fixture 90°, 180°, and 270° from the valve stem, insert the tire iron pry bar, and then use a wire brush or coarse steel wool to remove any rubber, light rust, or corrosion from the wheel bead seats.
