Recently, my wife and I decided to replace the aging tire inflator for our SUV. Sure enough, the older model P.I. Auto Store Premium 12V DC Tire inflator had served us quite well. I loved how fast it pumped air and the simple design that made it easy even for my teenage daughter to use it (yeah… you know how teen girls can be a bit hands-off when it comes to car matters….).
My wife, on the other hand, loves the convenience of not having to use lots of effort or soil her hands while doing it. Sadly, we had to let go of the unit because it had seen it all. Adding air pressure in the SUV, ATV, RV, motorbike, a bike, and the raft was not an easy fit.

How We Picked The Best?
To tell you the truth, modern tire inflators have really improved. They are more energy-efficient, work faster, deliver decent pressure, and are also more affordable. When comparing the available models, we mainly looked at the following:
- Pressure: The right product delivers good pressure and most will handle even large truck tires. Furthermore, the units work fast and you should be done inflating the wheel in a short time. Besides inflation, they also allow a user to reduce the pressure.
- Portability: We wanted a product that is easy to carry around and also store in the car. The units generally weighed between 1- 6 pounds and we steered clear of heavy-duty types, which although more powerful, are a little heavy and bulky. Another thing we looked at was the design. Good types were slim and can easily be placed in the palm of the hands and also come with handles.
- Pressure Gauge: It is important to make sure that the dial was easy to read and clear. A clear glass lens is better than a translucent plastic while bigger digits are easier to read than smaller ones. You’ll also find products with a backlit screen or led lights for use in the dark.
What’s More?
- Accuracy: Imagine inflating a tire only to confirm later that it was more or less by a few PSIs? To avoid such errors, we only go for renowned brands and also talk to people who have or currently own the units. Product reviews and expert analysis also come in handy. We noted that dials that go too high, for instance, above 250psi, were not as legible as those that don’t go above 200psi. This was because the former had the numbers a bit squeezed in the dial.
- Noise Level: My current inflator is powerful and delivers good pressure, fast. However, it is fairly loud and can be a bit of a nuisance. Closer investigations reveal that it had a decibel rating of about 90dB. This time around I was looking for units producing less than 85 decibels.
- Continuous Run Time: You are warned against running an inflator for more than 15 minutes nonstop since it may overheat and get damaged. The correct way is not to run it for nor more than 10 minutes, then allow it to cool down for about 30 minutes and then proceed. This can be a big challenge if you are inflating a big tire. During our search, we aimed for the ones with a long run time.
Other things we paid attention to include the design, weight, hose length, cord length, connections, and plugs, build quality, and price.
Importance of Having The Right Portable Tire Inflators
Many years ago, I never gave tire pressure the seriousness it deserves. I would go for weeks without checking the pressure and would only do so if I had a flat. I have also seen some people trust their eyes or kick the tires to ascertain if the pressure is enough (I have never understood how kicking a tire can tell you if the air pressure is okay…). The following are some dangers of driving on poorly inflated tares:
- Poor Handling: Unevenly inflated tires affect the handling and performance of the car. The car will tend to pull towards the side with the low-pressure tire. Over-inflated tires reduce the contact with the road surface and this affects the traction and increases the stopping distance.
- Noisy Drive: One of the signs that you have a flat or punctured tire is noise. You will also notice an unusual increase in noise if your tires are underinflated. This is because there is less bounciness and it doesn’t absorb the road vibrations and shocks as it’s supposed to. The affected wheel will also be more susceptible to the roughness of the road and impact.
- Poor Traction: According to tirebuyer, poorly inflated tires will provide bad grip on different surfaces. For instance, overinflated ones won’t maintain good contact on asphalt/tarmac or muddy/sandy terrains while underinflated ones will perform poorly on loose gravel or grasslands. A good portable inflator allows you to vary the pressure deepening on the terrain/surface. For instance, you will lower the pressure when driving on mud so as to increase the surface area and increase pressure on harder searches.
What’s More?
- Poor Gas Mileage: Underinflated tires will lead to an increase in the fuel mileage. This is because the low-pressure increases drag and make the engine work harder. It’s crucial to stick to the car manufacturer’s recommendations when it comes to pressure or the tire manufacture instructions in case you upgrade the wheels.
- Premature Wear: You can always tell that you are inflating your tires the wrong way by their appearance. Assuming it’s mechanically sound and the shock absorption system is okay, underinflating the tires makes the edges wear out much faster while overinflating it makes the center age much faster. It’s not strange for people to replace a tire that is barely a few months old just because it has worn out badly.
- Tire Blowout: Did you know that most blowouts aren’t caused by a manufacturing fault or sharp objection the road but by badly inflating the tires? The reading you get when the tire is cold will be lower than when it’s hot, or the car has been driven for a while. When it gets too hot or after driving for long distances, the reading can rise by up to 3Psi. In such a situation, a portable tire inflator will help you to reduce the pressure to prevent a blowout.
In Summary
You shouldn’t take your tire air pressure for granted. You also should not use crude methods such as trusting your eyes or kicking each wheel. With the right portable tire inflators, you will be able to inflate or deflate the tire effortlessly. This not only improves the drive quality, control, and safety but also extends the life of the tires. In the above review, I have taken you through the best portable tire inflators on the market. Additionally, I have taught you how to pick good portable tire inflators as well as the dangers of driving with wrongly inflated tires. Isn’t it time for you to acquire quality and reliable portable tire inflators for your car?
