Air Compressor Size to Fill Car Tires

what size air compressor do i need to fill car tiresProper maintenance of a tire is significantly essential for ensuring the safety of a car. The process of taking care of your car tire is quick and affordable: maintaining the correct tire pressure.

The National Highway Traffic Administration stated that most tire failures happen because of driving on under-inflated tires. Also, many other problems arise because of not having sufficient air in the tire.

On the other hand, an over-inflated tire will give you a bumpy ride, and car tires will soon be damaged.

So, it is significantly essential to fill up the tire with the right pressure. At this point, an air compressor is the best option. But the question is, what size air compressor do I need to fill car tires?

Well, in this article, we will look for the answer to this question.

What is an Air Compressor?

Air compressors have a small, motorized pump that gathers air from its surroundings and pumps it to a tank. The tank consists of a pressure switch that is responsible for monitoring the pressure build-up in the tank. When the compressor reaches its targeted pressure, the switch turns the compressor off.

Later, this preserved air can be used for different purposes.

Significant Specifications

Air compressors are available in many different shapes and sizes. These range from small, 12V air compressors that are part of emergency jumpstart packs and provide air in the car’s tire. On the other side, large and rotary pumps are used in the industrial site.

Learning about two significant specifications is essential. Because with the help of these two specifications, you will know the ideal size for routine automotive maintenance.

PSI: PSI stands for Pound per square inch. It is a unit of force that is necessary to take action. 90 PSI is the minimum requirement of maximum tools.

SCFM: The full form of SCFM is Standard Cubic Feet per Minute. SCFM is the volume of flowing air.

Now we have learned the definition and two significant specifications of an air compressor. Now the answer to the question “what size air compressor do I need to work on cars” is pretty straightforward – check the specifications of the tool and purchase an air compressor that matches it.

32 – 35 PSI is the recommended air pressure of a passenger car, and this range is made according to the car’s manufacturer. In fact, without any hassle, the maximum air compressor can efficiently deliver this air pressure. Since a conventional car compressor comes with 90 PSI air pressure, you can pick a regular air compressor without any tension to fill car tires.

Car tires contain valves in them, and CFM is not a vital factor, so bicycle pumps can also be used in them. However, around 4 CFM air compressors can reliably run a tire inflator.

How to Find Tire PSI?

Learning the tire PSI is not a challenging task. Either flip through the owner’s manual or look at the sticker pasted on the driver’s side door.

As I already stated, proper PSI is significant to ensure the tire’s longevity and safety.

When the tire is in cool condition, you will get an accurate PSI reading of a tire. Because of the outside temperature, tire pressure may change, so it is advisable to check the tire PSI at least once a month. Thus, maximum safety will be ensured. It would be best to take your car to a professional mechanic for further assessment of the vehicle.
