Temperature swings, leaky valve stems, coming home from a track day. They're all situations where you might find yourself needing a portable tire inflator. Gas stations with air pumps are getting harder to find, and those that are still around are charging $2 or more just to let you put water-filled air into your tires in an emergency. Forget about hunting for a pump, a portable tire inflator lets you air up when you need it and where you need it. We've asked you our readers along with our team of experts to help find the best portable tire inflators for your Hyundai.

Milwaukee M12 Compact Inflator

The M12 comes recommended by multiple users including @hochiinn because of its speed and durability. It needs a cordless rechargeable battery, but it can top off a car tire in under a minute. It also has automatic shut-off technology to stop pumping when your desired pressure is met. A 26-inch hose makes connections easy even if your valve stem is at the top of the wheel's rotation and the pump can deliver more than 120 psi for use on bicycle tires and other inflatables.


Slime Tire Inflator

The Slime Smart Spare emergency roadside puncture repair kit is more than just a 12V portable tire inflator. It also comes with a can of Slime's emergency flat tire repair liquid. A can of this emergency flat repair can get you up and running in an emergency, working to fill small tire punctures from the inside. Not a permanent fix, this can get you off of the roadside and to a tire store for a new tire without waiting for a tow. The inflator is recommended by @The_K_Man and works with or without the flat tire sealant and can inflate a completely flat car tire in about eight minutes.


Ryobi One+ 18V Inflator

Ryobi's line of portable inflators come recommended by @dankap50 and others. The big perk of these is that they use the same 18V battery used by Ryobi's massive line of cordless tools. So if you already own some Ryobi One+ tools, you can use the same battery and save some cash. On the other hand, you need to make sure that you have a battery with the inflator in your Hyundai whenever you're out for a drive. Ryobi offers inflators with digital gauges and pre-set automatic inflation stopping or you can get lower-cost options that are much more simple. Either way, they're a great way to pump up your jam.


Viair 00088 88P Portable Air Compressor

Viair's compressors come highly recommended, and @SpinMap said it was their choice. This is a high-draw compressor so you have to hook it to your battery with the included alligator clamps instead of using a 12V socket in the cabin. For that bit of extra effort, you get a pump that can draw much more current. The extra current lets it work faster to fill up your low tires. It also comes with an LED light to help you see what you're doing in the dark and a brass twist-on tire chuck that will stay securely in place while you fill your tire. It's not cheap, but this is a solid portable pump that should last for years.

This is a new spin on the classic tire inflator. A tiny air pump that uses a powerful lithium-ion battery to make sure it works. This inflator weighs just over a pound, making it easy to transport. It can pump up a car tire in just a couple of minutes, with a digital gauge to show how much pressure you have. Ideal for cyclists, it's small enough to toss in a bike bag when you're making the switch from road to trail. With no long cables, it is easier to move around your car as you inflate all four tires. An LED light helps make sure you can see what you're doing (and be seen) even at night.


Portable Tire Inflator Tips

Portable tire inflators are great to have, but you need to make sure you actually have it with you. So if you've taken the inflator out to fill up something around the house, make sure it goes back in your vehicle. Re-wrap the cords, too, because they are delicate and can get broken if the inflator is bouncing around your trunk.

Keep that cordless inflator's battery charged. It's not much help if you have a low tire and a low battery at the same time. If you're not a person who is good at keeping batteries charged, consider an inflator with a cord. That way you won't need to worry about it. But if you are using a corded pump to fill more than one tire you should run your engine. You don't want to end up with a full tire and a dead car.
