If your tires are low when you’re on the go, you have two options. You can stop at a strange gas station and hope the stationary tire pump works. Or, there’s a more convenient alternative: whip out your portable tire pump - opens in new window or tab. at any safe location and quickly get the tire pressure back up.

Why Is a Portable Tire Pump Important?

A portable tire pump is an air compressor you can take on the go. It’s essential to any roadside emergency kit. If you drive on underinflated or overinflated tires, you risk your safety and cause unnecessary tire wear.

This problem leads you to replace the tires more frequently, which means more money out of your pocket. It also can reduce fuel economy, which also hits you where it hurts.

Even if your car tires don’t have a puncture, air can be lost over time. When the weather changes, air pressure changes dramatically.

If you notice the air pressure is down when you’re out, pull out the portable air compressor and pump them back up. This prevents you from having to find a local gas station with a pump, or waiting for roadside assistance.

How to Choose a Portable Air Compressor

Portable tire pumps might look the same, but they have essential differences. Here are some ways to tell them apart when thinking about buying one.

Thermal Overload Protection: If we can stress one safety feature more than anything else, it would be thermal overload protection. You won’t find this feature on cheap, unreliable air inflators. Inexpensive models can overheat and burn out very quickly. The thermal overload protection ensures it doesn’t overheat and keeps you safer during operation. It’s worth the extra cost.

Construction: It’s essential to evaluate how the tire pump is made. Cheap inflators are made of plastic and have smaller, inadequate motors. These pumps regularly break and can crack with the slightest impact.

A high-quality tire pump will last for many uses. You can count on it when you need it to work. Some models use alligator clamps instead of standard socket plugs for the power supply. With models using alligator clips, you can expect a higher current to drive more power, so you don’t spend as much time on the side of the road. The alligator clips require you to open your hood to clip onto your car’s battery, where the 12v socket plug easily pops into your cigarette lighter socket.

Convenience: Cheaper models can be clunky and hard to use. The air may pump out slowly or need to take breaks to keep from overheating. Inflating tires with a cheaper unit could take you twice as long.

Instead, choose an inflator that moves a lot of air quickly and comes in an easy-to-carry package that’s easy to store in your car.

You may know how to put air in the tires but need to learn about using a portable tire pump. It’s not much different from what you do at the gas station. Here are a few tips.

Check the tire pressure. It’s best to do this when the tires are cold because warm tires lead to an inaccurate psi reading.
Connect your inflator. Depending on the power source, you may need to install the battery, connect the device to the socket plug, or use a 120-volt outlet.
Attach the air hose to the valve stem.
Set the desired pressure on the inflator. Not all models have this feature, so use your judgment and check the pressure frequently.
Disconnect the inflator. Once the target psi has been reached, turn off the inflator and disconnect it from the valve.
Be careful not to let too much air out.

Recheck the pressure. It should match what’s on the vehicle placard in the driver’s side door or your owner’s manual. Add or release air as needed.
