The proper way to tighten lug nuts is to first put the tire onto the studs with the vehicle jacked up. Then put on the lug nuts and tighten them finger tight. Do not put any sort of lubricant or anti-seize on the threads. The torque specification for your vehicle is based on clean dry threads.
How much torque does it take to remove a lug nut?
Car lug nuts are supposed to be torqued to about 100-120 ft lbs, but too often even the pros won’t take out a torque wrench, instead they’ll sow them on with an impact, set a lot higher than 100 ft lbs.
Can you over tighten lug nuts with a torque wrench?
To compensate for any possibility of loose nuts and bolts, technicians often are tempted to over-torque the wheel hardware. The improper use of tools, such as impact guns, can result in the same dangerous outcome or worse, as over-torqued lug nuts can cause permanent damage to them.
