The correct application of the torque Steel rims is crucial for driving safety. Incorrect torque can cause serious problems Security flaws which not only increases the risk of an accident but can also lead to expensive repairs. Correctly applied torque ensures sufficient Preload force of the wheel nuts, which prevents the screws and thus the wheels from coming loose while driving. A torque too low leads to a inadequate Preload force, which poses the risk of wheels coming loose. A too high torque On the other hand, the required preload force is exceeded and the screws are set excessive pressure which can cause the screws to tear off and damage the threads of the wheel suspension.
Torque for Steel rims
The ideal torque for the Wheel bolts for steel rims can usually be found in the Vehicle manual. It is usually between 80 and 160 Newton meters (Nm), but varies depending on the vehicle manufacturer and model. To apply the correct torque you need one torque wrench , or Pneumatic screwdriver with torque limitation. Both tools help to precisely adjust the torque and prevent the screws from being overtightened. Application of Torque: When tightening the wheel nuts with a torque wrench, it is important that the Thread grease-free are. Lubrication of the threads can lead to incorrect preload as the reduced friction causes the torque wrench to achieve the specified torque reached earlier, than it should actually be the case. This can also lead to the screws breaking off.
Torque table for steel rims
The required torque depends on the Size of steel rims and the Number of wheel nuts. Unfortunately, there is no generally applicable torque table for steel rims, as the requirements vary depending on the manufacturer and model. As already mentioned, you can find the exact information in Vehicle manual, in various forums or in the Rim assembly instructions, if you do not use the manufacturer's original rims.

Conclusion
- Compliance with the correct torque when assembling Steel rims is crucial for the safety of the vehicle. Too high or too low a torque can lead to safety risks and expensive damage. Always use a torque wrench and refer to the vehicle's manual or wheel manufacturer's documentation for specific information to ensure the vehicle's wheels are securely and correctly mounted.
