Best Portable 12V Air Compressor/Tire Inflator in Canada in 2022 | Comparison of the trusted brands

What is the best portable air compressor/tire inflator? A portable air compressor will save you from any troubles with your truck tire both in on-road and off-road situations. However, to be on the really safe side, you have to select a reliable and handy tool. The air compressor for trucks should be strong enough to refill the larger tires up to the required pressure levels within a short and uninterrupted runtime. For better convenience, most of the models are offered with backlit LCD displays. Besides, it should have an auto-shutoff function, and a pressure gauge to enhance the safety and accuracy of use. Viair 400P-RV air compressor includes all the above-mentioned features and even more. It is good for small ATVs, trucks, SUVs, and sedans with up to 35" Tires.

Aside from reliability, it has an impressive performance. It can refill tires up to 35 inches, with a max working pressure of 150 PSI and an airflow of 2.3 CFM. These ratings contribute to the stability and quickness of the inflating process. The Viair 400 model has a duty cycle of 33% at 100PSI, that is, 20 minutes of a continuous operation before it has to be cool down.

For comparison, the VIAIR 450P-RV model is a slower filling compressor, due to the lower CFM, but it can be run continuously at 100psi for up to an hour before needing to cool down.

It also features a tire inflation gun, a pressure gauge, an auto-shutoff, an air hose, multiple useful accessories, and a carry bag. Indeed, everything that you might need is right in the box; it means no extra costs to bear!

How does it work? | The Essentials

As soon as you have activated your air compressor, it starts to suck the atmospheric air. Then the latter is exposed to compression by means of an integrated pump with further storage in a tank. As the airflow is coming from the compressor to drive air tools or inflate tires, the pressure level in the tank is gradually decreasing, and the motor is automatically reactivated by a pressure sensor and an on/off switch. The motor starts the pump each time until the pressure reaches a preset level in the tank.

PSI and CFM generated by the portable air compressor are important factors influencing the result of inflation. The pressure required for the tires of your vehicle is usually specified by the manufacturer. Every new vehicle will have a pressure rating label located on the driver’s side door jamb. Otherwise, the correct tire pressure may be found in the user manual or from a local dealer’s service center.

Knowing the value you can avoid over-or underinflation, which contributes to the safe and long-lasting life service of the tires.

CFM or cubic feet per minute is the most important measurement unit for a portable air compressor for truck tires. It shows how much air a compressor can deliver in a particular period of time. When filling a large cross-country truck tire, you would most appreciate it if it takes as little time as possible. As truck tires are larger than those of the cars, they need bigger air volume to be blown into.

PSI or pounds per square inch is a less important metric for a portable air compressor because most truck tires rarely need more than 50-55 PSI. Every light duty pump can reach these volumes. Just bear in mind, it’s better to inflate quickly your tires to the right pressure than to generate an extra high pressure for a long period of time.

Portable air compressors for car and truck tires, how do they differ?

Overall, these tools have the same concept of operation and do not differ from each other considerably. However, the only difference is in the power ratings. For car tire inflation, a small compressor with as little as 1 CFM really does its job even when inflating flat tires.

Filling the truck tires requires higher PSI and CFM depending on the model of vehicle, type of cargo it is designed to transport, and weight.

In fact, truck tires may be inflated with relatively big and heavy-duty air compressors. On average, the best portable air compressor should be able to deliver at least 1 – 2 CFM to inflate the large truck tires.

What to look for when buying a portable air compressor?

Below I have summarized the main features to bear in mind when searching for the best air compressor for truck tire inflation.

• PERFORMANCE. The features and specifications of a unit you are going to buy are highly important for considerations. Choose the one with more CFM and PSI and other parameters which directly affect the efficiency of large tire inflation of different heavy-duty vehicles starting from RVs to off-highway trucks. If you are looking for a commercially oriented compressor, you would better select an option with a larger tank. The latter will allow you to operate the compressor for extended periods with the more intensive airflow which is critical for truck tire inflation.
• DUTY CYCLE. It refers to the amount of time taken to cool down the air compressor entirely after each use. For instance, if your air compressor has a 100% duty cycle, it means that the unit can be operated continuously without any breaks.

• PRESSURE GAUGE. A tire pressure gauge is designed for checking the tire pressure, so you can easily inflate or deflate tires to the optimal pressure level as soon as it is needed.
• POWER SUPPLY. This is of less importance for the operation of air compressors for tire inflation purposes only, as most of the models come with an adapter that can be plug into the cigarette lighter of your vehicle. On the other side, it could be very useful to have both DC and AC adapters enclosed, as the air compressors for truck tires can be used for household purposes as well. Otherwise, you can buy such an adapter additionally. Besides, currently, there are many options that are powered by rechargeable batteries. The perfect air compressor for your truck should be suitable for any of the above-mentioned power supplies.
• STABILITY. The stability technology will ensure the desired durability of your portable air compressor. It is possible due to the ability to absorb vibrations and stay in one place while you are inflating your truck tires. Besides as it will contribute to fewer vibrations, the noise level will be also reduced, which is always an advantage.

• COST. Right of the bat, the size and type of compressor you choose to buy is pegged on how deep you are willing to dig into your wallet.

You should realize that the more powerful and versatile an air compressor, the more expensive it may be. This simple cause-and-effect is pretty clear. However, you shouldn’t stick to this point. Instead, you should buy the one that is capable to handle your needs. Rely on trusted manufacturers, reviews, your own experience, and this Buyer’s Guide, and you will definitely succeed in making the right choice!

How to define the right pressure for truck tires?

Trucks are usually classified differently than passenger cars due to the fact that they are designed for heavy-duty work. They are divided into two categories: light and heavy.

Light trucks like SUVs, pickups, and RVs usually carry passengers like regular cars. The difference is that they have an off-road capability since their tires are designed for rough terrain.

Heavy trucks like fire trucks, buses, dump trucks, agricultural vehicles, tankers, etc., are designed to deal with heavier cargo. Their tires are also of the off-road type.

Thus the average tire pressure in a truck tire varies from model to model. It depends on the traveling speed of a vehicle, the type of cargo, and the environment in which it will travel. According to the Society of Automotive Engineers, the average pressure in a truck tire can range from 30 to 100 PSI.
