Everybody knows the feeling. You go to your car, bike, or another machine with a tire and see that there is not enough air in it. It means you have to use a pump or an air compressor. Using an air compressor is quick and most have a pressure gauge to see how much air has to be added. In recent years a lot of new models have been launched more targeting at inflating tires or other equipment that need to be filled with air like a small rubber boat or a bounce house. Those air compressors are much smaller and portable than regular air compressors.

Tire Air Compressor buying guide
Before purchasing an air compressor for your tires, there are certain features to look for:
- Pressure gauge: This helps you see how much air is already in the tire, and can notify when you have reached the correct pressure.
- Flashlight: To help you see clearly if you have to use it at night.
- Shutoff system: Some models have a shutoff feature, which allows it automatically to stop once the tire is inflated and has reached the designated pressure.
- Portability: What is the weight of the size of the model, and do they have a battery? In general portable models are less powerful, and have a smaller tank than the bigger nonportable models. If this is ok for you will depend on your use case. If you want to use it to power air tools, a small portable machine will not be sufficient.
- Batteries: Battery-powered air compressors can easily be moved and taken to any location. An important aspect is the running time of the air compressor. Most models will be ok for a tire, but inflating a boat or bouncing house can be a problem. In that case, you need to hook it up to the mains.
- 12 Volt or Mains: Can the air compressor be run from a 12 Vols supply? In that case, you can use it much easier outside your house, or on the move. Be careful not to use it too long as your car battery could drain quickly using it. In that case, you could run your engine and use it. If the model can only run from the mains it will be less flexible, but often has more power.
- Accessories: Does the air compressor comes with accessories to inflate other products like a bicycle tire, or an air mattress, or a boat? Most inflatable products use a different plug than your car tire. If you do not have a matching plug is can be really difficult to use it in those situations.
Portable Air Compressors
Portable air compressors are popularly used to inflate tires and often come in handy, especially when it comes to avoiding a roadside emergency or being able to quickly pump up sports equipment, air mattresses, and inflatable toys directly from your car. With so many portable air compressors in the market, it can sometimes be a herculean task to know which is best. Below is a list of the 10 best portable air compressors and their unique features.

The Breezz Air Compressor is powerful and fast. It will inflate a car tire in 4 minutes up to 35PSI. Other features include Long cord reach, LED light, easy to read display, Auto-stop, and Durable ABS plastic and stainless steel body.
CFM Tire Pressure Measurement
CFM means Cubic Feet per Minute and has been termed as the most common way to measure airflow. The CFM is used to find out how much pressure a piece of equipment can provide and the rate and volume by which the equipment tightens the air. As a well-known rule, tire inflation should use an air compressor to produce at least 1-to-2 cubic feet per minute (CFM). Portable compressors powered by an electric cigarette lighter tend to produce far less than 1 CFM and are mostly only suitable for emergency inflation in the absence of other options. Car air compressors that work with a tank which stores the pressurized air is the most efficient. This will aid in the quick inflation of car tires, bicycle tires, and even truck tires.
Note: Most small air compressors targeting tire inflation will not mention the CFM.
Common Terminologies Relating to Air Compressors
Having an understanding of how the air compressor works is easier if the technical terms are known. A few of these standard terms have been defined below:
- PSI: PSI stands for pounds per square inch and is used to measure pressure.
- CFM: CFM means cubic feet per minute, and it measures the volume of air passing over an area per minute.
- SCFM: Stands for Standard Cubic Feet per Minute. It measures the flow of gas under standard pressure and temperature conditions.
- Horsepower: The horsepower is used to measure the performance of an engine as well as how powerful the engine is.
Maintaining an Air Compressor
Like any other mechanical device, it is essential to perform routine maintenance to increase lifetime. If you have a small portable battery-powered air compressor that you use for tire inflation there will not be a lot of maintenance required. Read the owner’s manual what is required for your machine. If your air compressor is battery powered you can extend its lifetime by charging it correctly, and only when needed. Also, check and clean the part plug connects with the tire.
If you use a bigger air compressor that is powered by the mains or a gas engine there will be more maintenance required. Regular inspection will prolong its life pan:
- Manual: Ensure the user manual is read
- Leaks: If your model uses oil check for leaks. and air leaks check
- Nuts: Tighten nuts and bolts
- Hose: Check your hose and adapter. If it does not work ok clean it.
- Shutoff system: Check the air compressor shutoff system
- Pressure: Check the differential pressure in the compressed air filter
- Oil: Determine if there’s a need to change the oil in the compressor.
- Gas Engine: If your air compressor uses a gas engine it needs regular maintence.
- Temperature: Check and ensure the operating temperature is at a safe level
- Condensation: Drain condensation from the air tank. It can contain a lot of water, depending on the humidity level and how often you use it.
Note: These tips do not apply for all small portable air compressors.
Frequently Asked Questions
● What Size of Air Compressor is needed for Airing up Tires?
You will only need around 4 CFM to reliably run a tire inflator and get it to work with a wide range of tires. The recommended PSI for passenger cars is 32 to 35 PSI, and so you can quickly fill up most vehicles with your typical 90 PSI compressor.
● What are the signs to show my tires need air?
Some red flags to look out for to help you know that it is time your tires need air is when the gas mileage becomes poor, and the steering is off.
● How do I repair a 12 Volt air compressor?
If you can repair your 12 Volt air compressors will depend greatly on the problem. It can be something simple as a fuse, but if your motor is damaged it probably will not make a lot of sense to try to find a replacement.
In most cases, it is not difficult to open the air compressor, and due to the 12 Volt power, there is no big danger. use Google to see if somebody had your problem before and has given a fix for it.
● Can I inflate my tires in cold weather?
Yes, you can inflate your tires in cold weather without any problem, but you have to use slightly higher pressure to compensate for the cold. When the tire is getting warmer, or the ambient temperature will rises the tire pressure will increase a little bit.
We hope that this article was helpful, and makes choosing a compressor for your tire more easily.
