So, let’s find every possible way! 

What is an Impact Wrench?

An impact wrench is a mechanical power tool that is used opposite of a socket wrench. It provides high torque impact to remove lug nuts from cars or trucks without allowing too much pressure. 

Moreover, it is powered (pneumatically or electronically) through a motor. The motor powers faster the torque process on tires hard lug nuts or bolts and finishes the job within a few seconds.

You will hear a perfect click sound when they match perfectly. If you are done, it will be time to place the vehicle to remove the lug nuts.

Test the Machine and Correct the Speed

Run the impact wrench for testing the machine direction. If you see it is rotating in the wrong direction, press the knob to reverse the impact socket’s direction positions. Remember, Anti-clockwise rotation loosen the lug/nut/bolts and clockwise for tightening them. 

Depending on RPM (Resolutions per Minute), you can adequately measure the impact wrench’s speed. Therefore, high torque impact can achieve a lower RPM and for low impact high RPM need to deliver. So, depending on job requirements, you can set your right RPM. 

Time to Finish Work

Now you’re done with all the basic things, and it’s time to change tires by loosening the nuts. Apply brakes that ensure the vehicle stands still. Now line up your impact wrench and socket into the tires nuts or bolts.

If you give pressure on the lug nuts, it may damage the tires and wheels. Because too much torque is difficult to control at work. So, better to use them precisely to avoid these sudden incidents. 

Undoubtedly, the impact wrench is the most useful power tool to loosen the stubborn lug nut or bolt. We try to give you the right idea on How to use an impact wrench to change tires. We hope next time it will be easier for you to deal with changing tires.
