Proper lug nut torque is essential for your Toyota's safety and performance. Incorrect tightening can lead to loose wheels or damage. Refer to your owner's manual for the exact torque specification for your specific model, but generally, most Toyota cars require 76 ft-lbs of torque, while trucks and SUVs like the Land Cruiser and Tundra require 98 ft-lbs. Always use a torque wrench for accurate tightening and recheck the torque after 50-100 miles of driving.
