What size impact wrench is needed to remove truck tires?
2 Answers
Removing truck tires requires an impact wrench with 65-120 kg of torque, but based on personal experience, those below 90 kg are not durable. The torque of pneumatic impact wrenches used for repairing passenger cars generally ranges between 50 to 70 kg. Introduction to impact wrenches: An impact wrench is a pneumatic tool, named for its loud noise during operation resembling cannon fire, also known as a pneumatic wrench. Its power source comes from compressed air output by an air compressor. When compressed air enters the cylinder of the impact wrench, it drives the internal impeller to rotate, generating rotational force. The impeller then drives the connected striking mechanism to perform a hammer-like motion, tightening or loosening screws with each strike. Structural classification: There are many structural types. Some observed include single hammer with pin, double hammer with pin, triple hammer with pin, quadruple hammer with pin, double ring structure, and single hammer without pin structure.
I've been working on heavy-duty vehicle repairs for over a decade. When removing truck or construction vehicle tires, the pneumatic impact wrench needs to pack enough punch. A model with around 1000 Nm of torque is most reliable, and common 1-inch drive tools will do the job. Don't cut corners with smaller ones—wrenches under 500 Nm of torque won't budge the nuts and will just waste time or even damage the tool. Make sure your air supply pressure doesn't drop below 6 bar. In cold winter weather, nuts tighten up even more, so it's best to crank the pressure a bit higher. Regular maintenance is also crucial—keep the impact wrench lubricated to prevent internal rust. Always wear anti-slip gloves and safety goggles, and ensure the vehicle is securely supported without any wobbling. For beginners, investing in a professional-grade impact wrench from the start ensures durability and safety. With more experience, you'll come to realize that tools are the lifeblood of vehicle repair—using them right makes the job smooth and efficient.
