The appropriate torque for lug bolts varies depending on the vehicle and can range from 50 foot-pounds to 350 foot-pounds. The correct torque specifications for a vehicle can be found in the owner's manual, at a vehicle's dealership or in a repair manual for that specific model and year.
Torque specifications for lug bolts vary by the size of the bolt, the size of the wheel and the wheel material. For example, a vehicle with aluminum wheels would require lower torque than the same vehicle with steel wheels. These specifications are normally for clean and dry parts; lubrication and rust affect torque.
