Keeping your car's tires properly filled with air ensures that they wear evenly and will maximize your fuel economy. It's one of the most important aspects of automotive maintenance that anyone can handle, no matter their experience level. A portable tire inflator is a tool you'll need to get the job done without the help of a mechanic. These are our favorite tire inflators for doing routine auto maintenance at home.

Pump 'em up

All of these models feature an easy-to-read PSI gauge so that you can know precisely when your tires are at the right level. And many of them are useful for more than just filling up car and bike tires. However, we think the EPAuto 12V DC Portable Air Compressor (opens in new tab) is the best choice for most people. The display and controls are easy to read and use, there's a sturdy carrying handle built into the top, and the powerful light makes dark roads no problem. It's also the only option that comes in four colors.

If you're more experienced with automotive maintenance -- we're talking getting under the hood to connect things -- then the Viair 88P Portable Air Compressor (opens in new tab) is the best option for you. It connects to the car battery and can handle the truck tires with no issue, unlike the other options listed here. It also has a very long air hose, which is great for taller vehicles like SUVs.
