I've been using 65 ft-lbs for my Volvo's with aluminium wheels all my life. Running 15" to 18" wheels, same torque.
They have the same 12 x 1.5 mm thread. Never broken a stud and never had a nut loose. (Maybe Volvo has better quality studs?)
Oh, and we have winter wheels here, so the wheels get changed twice a year.
