The torque specs are dependent on the lug nut size.

If the lug nut is 7/16 inch the torque should be between 55 and 65 ft-lbs. For 1/2 inch it is 75-85 ft lbs. For 9/16 inch lug nuts the torque is 95-115 ft lbs and for 12 mm the torque should be between 70-80 ft-lbs. Finally, for 14 mm lug nuts the torque is 85-95 ft-lbs.

These specs are all based on a steel wheel and for wheels between 8 and 14 inches diameter.
