Why do you need a portable air compressor for trucks?
Tire puncture or flat tires are not something unexpected for the experienced drivers. In this regard, they have a binding rule of ensuring an air compressor within reach before starting the engine. The commonly used tool should be relatively lightweight and compact, providing the possibility to find enough storage space in your vehicle for it. Although such air compressors are small-size units they have to deliver enough power to handle hefty tire inflation easily and quickly.
In case of damage of the truck tire, the only right and efficient rescue option will be usage of a specific heavy-duty air compressor. Otherwise, this procedure will take a vast amount of time and a lot of efforts.
For instance, truck tire inflation with a weak and unsuitable compressor will bring no result at all. Thus, choosing the right portable air compressor for a truck is not an easy thing, as it seems to be. More than that, it will require plenty of various preliminary considerations from your side. So, let’s make the process easier for you!
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 air flow 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 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 under inflation, contributing 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 mostly appreciate if it takes as less 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 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. In 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 for trucks?
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 larger tank. The latter will allow you operating the compressor for extended periods with the more intensive air flow 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
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 operation of air compressors for tire inflation purposes only, as most of the models come with an adapter which can be plug into the cigarette lighter of your vehicle. From 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 adapter additionally. Besides, currently there are many options which are powered by rechargeable batteries.
The perfect air compressor for your truck should be suitable for any of the above-mentioned power supply.
STABILITY
The stability technology will ensure 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 less vibrations, the noise level will be also reduced, which is always an advantage.
LCD SCREEN
Since it is necessary to check the readings when inflating the tire, it’s preferable to choose the air compressor with a large LCD display. The LED lightening should be sufficient enough for a convenient use during night hours or under bad lights.
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 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 for deal with heavier cargos. 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.
