Portable tire inflator
Set all four tires to spec in the driveway instead of fighting the gas-station machine.
01
Where to buy
02
Why you need it
- Correct pressure is the easiest fuel-economy and tire-life win there is, and it changes with every cold snap.
- A 12 V or cordless inflator with auto shut-off hits the number on the door sticker and stops.
- Keeps a slow leak drivable until you can plug it.
03
What to look for
- Auto shut-off at a preset pressure.
- 12 V plug-in units are cheap and never run out; cordless units are convenient if you already own the battery platform.
- Flow rate: a small inflator takes minutes per tire on a truck. Look for 30 L/min or more.
- A screw-on chuck seals better than a lever chuck on short valve stems.
