Mobile Tire Changing Pros: Should you use cordless or air impact wrenches?

January 30, 2018

Impact Wrenches Tools

Getting the job done quickly is a main concern for tire changing specialists, especially when they are on the road. Therefore when changing tires, one of the most important things to consider is which type of tool to use to get the job done fast.

Over the last few years the tire shop business has evolved quite a bit. More and more tires are changed outside of traditional tire shops, and we saw the arrival of new players offering roadside assistance and tire changing services at convenient places for customers, like their homes. In turn, these new services created specific needs in the market for new tools and equipment for operators.

Pneumatic tools have historically been the preferred choice in the tire changing industry due to their design and performance. However, cordless electric tools have now become more popular, especially in applications requiring a high level of mobility. So how do you know which type of tool to use? Check out the benefits of each below.

The benefits of electric cordless impact wrenches:

Often seen as the best solution for mobile tire changing specialists, electric cordless tools offer a lot of benefits favored by operators. Since tool manufacturers have developed high performance cordless electric impact wrenches to be able to work anywhere and at any time, the freedom of movement they allow has been well received by operators. Mobility is without a doubt the main benefit of this technology, and is even more valued by mobile technicians who are not able to park close to the job, or are working in difficult conditions. These situations require high running tool time which is now possible thanks to the new Lithium-ion batteries (up to 6 Ah / 9 Ah).


Even if cordless impact wrenches are a little bit heavier than similar air tools, they provide great comfort and ergonomics to operators. Newer tools are even coming out with helpful functionalities, such as overtightening prevention and no-impact screwing options.


It’s important to remember that cordless tools are powerful, and their technology is still (and will always be) dependent on the battery charge level. Dear cordless tools users: don’t forget to check your tool battery level!


The benefits of pneumatic impact wrenches

On the other side, many impact wrenches users, including mobile “tire changers”, are still using pneumatic tools. One of the main advantages of using a pneumatic tool, besides its lower cost compared to cordless, is its power-to-weight ratio with an average weight of 4.4 lbs - 2kg (for an average high performance and durable composite impact wrench). At the end of a working day, this makes a real difference!

It is also important to consider the tool’s conditions of use. In some situations when bad weather conditions (extreme cold, rain…) could damage a cordless tool, pneumatic impact wrenches will last longer, as they are extremely resistant to those types of environments.

Pneumatic tools are also appreciated for their great compactness (enabling different application usage with the same tool) and their lower vibration transmission while in use.

“Whatever you choose, don’t forget that a torque wrench is necessary to properly tighten any wheels.”

For tire changing applications, the best choice between cordless electric and pneumatic impact wrenches will differ depending on if you are looking at a workshop or a mobile job. Even if both options are suitable, pneumatic versions are typically preferred by operators who like lightweight tools, whereas cordless impacts are the tool of choice for mechanics who are looking for higher freedom of movement.

Pneumatic and cordless impact wrenches are your best partners for everyday tire changing, and depending on your specific needs, both versions can be complementary.

Getting the best torque control from your wrench

15 October, 2018

Pneumatic impact wrenches were originally meant for loosening stubborn nuts and bolts. However, nowadays mechanics use impact wrenches for tightening bolts too, for example on wheels, so they can do their jobs faster, with more efficiency, and increased safety. Here’s some insight on torque regulation and how to make sure the tools is performing as expected.

What can I do to limit vibrations for the operator? What solution exist on the market to reduce grinder’s vibrations?

Limiting vibrations – it’s all in the balance

17 September, 2018

Power tools are a key to productivity in the oil & gas or the metal working industry. Maintenance and production tasks must be carried out efficiently, however intensive use of vibrating power tools, such as grinders, can expose operators to Hand Arm Vibration Syndrome (HAVS). How can we reduce risks, improve productivity and reduce abrasive costs at the same time?

Tools calibration: why is it important?

20 August, 2018

Calibration process is a vital step in ensuring tools are working as they should be, giving correct readings, providing a safe working environment for end-users, and ensuring that companies are upholding their legal obligations. However, calibration is often confused with accuracy and precision. Here we explore what exactly is meant by calibration and why it’s so important.
