The Buick Reatta lug nuts should be torqued to 100 ft-lbs using a calibrated torque wrench (if available). They should be torqued evenly in a crisscross tightening sequence, gradually increasing the torque until full torque is reached. A light coat of oil on the threads is desirable to insure proper torque.

Always start the lug nut on the lug bolt by hand for a few turns to prevent cross threading.
