Factors to Consider Before Buying the Best Wireless Impact Wrench for Changing Tires

1. Torque

Before buying the best wireless impact wrench for changing tires, you need to understand that torque is vital; that is the tool’s twisting force. Some manufacturers usually state the torque in inch-pounds of force, while others use foot-pounds. However, don’t automatically conclude that you need the highest amount of torque from your impact wrench; too much torque, and you will find your nuts snap in half.

Generally, you will find impact wrenches with torque as low as 1,200 inch-pounds (100 foot-pounds) and as high as 12,000 inch-pounds (1,000 foot-pounds) and everything in between. If you aren’t working in professional auto shops, a wrench driver towards the lower end of that range is more than enough, while a wrench driver in the mid-range is ideal for most automotive work.

2. Speed & RPM (Revolution Per Minute)

The rate at which an impact wrench spins is measured in revolutions per minute (RPM). Electric, air, and cordless impact drivers are also measured in impacts per minute or IPM. This number usually shows how many times the hammer actually strikes the anvil over a minute. The higher IPM or RPM, the more power you can expect to receive.
