It's time to do a quick fitness check on your ride. Tires are the legs of your car: When they're in good shape, the whole body can perform well; when they're not, everything is rough and sluggish. Maintaining optimal tire pressure is important not only for safety but also for your car's fuel efficiency — it'll save you money and make your ride a lot smoother. A portable digital tire pressure gauge makes it a lot easier to keep tabs on the integrity and performance of your wheels. We've found a standout Amazon Lightning Deal on a gauge that fits right in your glovebox — just $9, down from $15. Meet the super-slim, No. 1 bestselling AstroAI Digital Tire Pressure Gauge.

$9 at AmazonWhy is this a good deal? ????
Yes, you're getting this handy gizmo for next to nothing. It's an impressive 40% off! But it's also a long-term money-saver that will help you get better gas mileage, meaning this one-time purchase could potentially pay for itself in a few fill-ups. According to the U.S. Department of Energy, the proper tire pressure can improve your gas mileage by up to 3%.
Why do I need this? ????
Tires should maintain a certain PSI (pounds per square inch), which is usually marked on your tires or your car's door jamb. This is not just a throwaway number — the measurement is important for safety, fuel efficiency and much more, so you want a correct reading.
Many people avoid car maintenance because it's confusing, inconvenient and expensive, but shoppers say this little helper hits the mark on all fronts. Simply place the lighted nozzle on your tire valve and the gauge will report the tire's pressure. It even lights up for easy nighttime readings — no more fiddling in the dark with that old-school gauge that makes you guess the exact pressure.

What reviewers say ????
Over 46,000 Amazon shoppers have given this gauge a perfect rating.
Pros ????
"I compared readings to an expensive old-style gauge and measured the same pressure. It’s easy to hold and to place on the tire valve without leaking air, and the LED is handy since I usually measure my tires at night," wrote a fan. "The measurement reading is displayed quickly, and the display and LED light turn off after several seconds of no use."
Sometimes even tire technicians and other auto pros make mistakes. "Saved my tires!" said a grateful reviewer. "I had two new tires put on and didn't know that the guys put 40 pounds of air in my back tires when they should have put 30. The alert kept going off in my car, so I used this digital tire pressure gauge and saw that 10 pounds of air needed to be removed. No more alerts!"
One appreciative reviewer said this gauge "worked better than expected. It is easier to use than the older style manual gauge and provided a very accurate reading. I was hesitant when I first used it because the reading seemed too low, but I went to the tire store to fill the tires and their pump delivered the same number."
Cons ????
The device comes with LR44 batteries that are easy and affordable to replace, but as one reviewer said, "Maybe make a more premium version that charges via USB? Outside of this problem, I think it’s a perfect tire gauge."
Another user disliked that there was no way to release excess air from a tire. The "only missing item is a way to release air when pressure is too high."

"It inflated from completely flat to full in a little over 3 minutes," said one user, who has experience with more than one brand of compressor. "I have DeWalt at work, and I like their portable compressor, but I prefer my Milwaukee tools that I use at home for everything else. So I took the plunge and I am happy."
