What to Know Before Buying the Best Tire Inflator?

Before you make a decision, it is wise to have little know-how about a tire inflator. There are a few things you need to take note of. First and foremost, you’ll need the proper tire inflator for your vehicle.

Not all inflator works on a large vehicle, for instance. Likewise, there is no need to invest in a large, heavy-duty inflator if you have a small vehicle. The rule of thumb is to get the right size for the vehicle.

The next important thing is to consider the amount you want to spend. However, this decision is somehow related to the amount of power you’ll get. Then, you can consider investing in an onboard inflator if you often go out.

So you can inflate your tires whenever needed. You’ll also find some inflators that can be installed with your vehicle’s battery or the 12V outlet inside. Last but not least, it is wise to check customer feedback before buying an inflator.

How to Find the Best Tire Inflator?

Choosing a suitable tire inflator is essential. Otherwise, you may end up stranded in the middle of nowhere. The model you bought may need a specific adapter to attach to your tires. Or there may be other specifications you may need.

However, here are some key considerations to keep in mind while looking for a tire inflator. Check out the following factors and make sure you don’t buy the wrong tire inflator for your vehicle.

  • Power Source

A tire inflator certainly needs a power source to fill the tires. Usually, it utilizes electric motors and pumps to do so. There are two ways how a tire inflator can pump up the tires, such as; cordless and corded.

Corded Inflators

Primarily, high capacity corded inflator uses a 12V power plug to your vehicle’s 12V jack. Or else, it can be plugged into your vehicle’s accessory port or cigarette lighter socket. Some can be clipped directly to the vehicle’s battery.

In either case, there shouldn’t be an issue if you are using it to inflate the vehicle’s tires. Corded inflators are easy to use as they don’t require any additional battery to operate.

The tire inflator can inflate as long as the vehicle’s battery has power. However, some models run on both 12V and 110V power. Those inflators require a power outlet.


Cordless Inflator

Cordless inflators, on the other hand, offer more flexibility than corded ones. The best cordless tire inflator doesn’t need an additional power source to fill the tires. You can use these for other applications like inflating bike tires, balls, firm equipment tires, sports equipment, etc.

  • Pressure

The pressure a tire inflator can produce is directly connected to the speed. The higher the pressure, the quicker it can inflate the tire. It is advisable to look for inflators with high pressure of at least 100 PSI.

A tire inflator can have a maximum pressure of 150 PSI which runs even faster. However, manufacturers mostly design tire inflators with 30 to 40 PSI. The best portable air pump for car tires will have this pressure range.

  • Inflation Time

The inflation time refers to the time it will take to inflate the tires. The majority of tire inflators have an average inflation time between 4 to 7 minutes. However, the high-end models can fill it in just 1 minute.

  • Pressure Gauge

A tire inflator comes with a pressure gauge that shows the amount of air the tire has. The best tire inflator with a gauge should be easy to read. However, a tire inflator can have a digital or analog pressure gauge.

Digital gauges are easiest to read, specifically if they include a backlight. Equally, analog gauges with large numerals are popular. But, these can be challenging to read as most analog gauges don’t come with background light.

  • Power Cord

The power cord is one of the negligible factors but essential to consider. Make sure you buy a tire inflator with a power cord that is long enough to reach the tires.

  • Hose Length

Filling a tire with short length inflator is not fun, but also, a long, tangled inflator is annoying. So, it would be best if you had a tire inflator with a suitable hose length for convenience. A tire inflator with a 16-20 inch hose length would be the best choice.

This length is sufficiently long to reach any tires but also manageable. Most corded tire inflator comes with a coiled hose. Those units are convenient as you can stretch them easily. You can consider buying them for large vehicles like SUVs and trucks.

  • Tire Compatibility

This factor is one of the most critical factors to consider. You buy a tire inflator that doesn’t have enough power to inflate the tires. Those inflators are of no use. Hence, it is essential to check the tire inflator’s capability before choosing one.

You’ll find the maximum size of tires a tire inflator can inflate. Thankfully, most manufacturers mention this with the product. However, you need to make sure your tire is equal to or less than the mentioned size.

  • Automatic Shut-off

The best portable air compressor for a car is stout and robust. But, it can overheat if it runs for longer. So, the tire inflator comes with a built-in automatic shut-off feature to protect it from overheating.

This function shut off the inflator automatically. However, the inflator decides this considering three measurements, temperature, pressure, and time. A hazardous temperature is typically around 200oF.

When the device starts reaching this temperature, it’ll blackout until it cools off. Then, you can set the pressure as you want. The inflator will shut off when the tire reaches this pressure.

After it runs for a prescribed amount of time, the cool-down process starts. This cool-down process can take around 15 minutes.

  • Weight and Portability

Tire inflators are popular because they are lightweight and portable than typical air compressors. But, there are also some heavyweight models which are difficult to handle in emergencies. The best tire inflator can be less than a pound. So, you can use those while heading out on a long road trip. It’ll fit nicely in the trunk.  

  • Warranty

As a potential buyer, you may have doubts about the quality of the portable tire inflator. A quality product comes with an extended warranty period. So, you can opt for those models with an extended warranty.

Most tire inflator comes with a 1-year warranty, while some brands like Milwaukee comes with two or more. Some expensive, high-end models come with a lifetime warranty.

Wrapping Up!

Buying the best tire inflator is an excellent decision for emergencies or disasters when on the road. You can keep it in your just-in-case bag of goodies. And, this won’t break the bank. Here we’ve some of the best options available in the market.

Each of them comes with unique features and specifications. You need to understand what is best for your vehicle’s specific requirements. That being said, TEROMAS Tire Inflator is more than enough for many buyers.
