Tires are sort of like the feet of your car ... when they're in good form, the whole body can perform well. But when they're in bad shape, everything is rough and sluggish. Maintaining optimal tire pressure on your car is not only extremely important for safety but also increases fuel efficiency, saves money and smooths your ride. A portable digital tire pressure gauge makes this easier than ever to keep tabs on, but how to pick the right one? We've found a standout Cyber Monday deal on a gauge that's just $10 (was $16). Meet the superslim handheld AstroAI Digital Tire Pressure Gauge.
Tires should maintain a certain PSI (pressure per square inch), which is usually marked on the side of the tire or on the side of the door. This is not just a throwaway number — the measurement is important for safety, fuel efficiency and much more, so you want a correct reading.
But let's face it: Most people don't do car maintenance if it's a pain, confusing or too expensive. Shoppers say this little helper hits the mark on all fronts. Simply place the lighted nozzle on the valve and the gauge reports your tire's pressure. It even lights up for easy nighttime readings; batteries included. No more fiddling with that old-school gauge that makes you guess the exact pressure (Is it lined up with 57 or 58? Or is it closer to 56?)
What reviewers say
More than 44,000 Amazon shoppers have given this gauge a perfect five-star rating. Read on to hear what all the fuss is about.
"Great tool to keep in your glove compartment," wrote another fan. "Even if your tires 'look' like their pressure is OK, this tool will give you an accurate reading! With gas prices rising, well-inflated tires are important to save gas."
Sometimes, even tire technicians and other auto pros make mistakes. "Saved my tires!" said a grateful reviewer of the gauge. "I had two new tires put on and I didn't know that the guys put 40 pounds of air in my back tires when they should have 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!"
"Easy to read, day or night," reported another happy shopper. "Pretty neat little gauge. It has metric to SAE readings for air for your tires or other things you need to fill up. Has a great little blue light or background so you can read it during the day or night for those hard times when you're trying to put air in your tire at the gas station and you can't read it with the plan gauge."
One appreciative reviewer deemed this gauge to be "as accurate as my $90 Motion Pro 08-0684 digital gauge; they actually read exactly the same at [a fraction of] the cost. This proves tire pressure gauges don't have to cost a fortune to be accurate... Digital is definitively better than analog bourdon tube mechanisms. Incorrect tire pressure translates to premature tire wear, degrades ride quality, can increase fuel cost and cause long-term suspension damage. To me, anything beyond a 1.5 lbs reading error is a big deal and unacceptable. I recommend this gauge."
This slim, portable gadget is great for checking motorcycle and bicycle tires on the fly. A pleased cyclist wrote: "I use this for my bicycle as it is more accurate for weighing, easy to connect, lightweight and lights up for easy reading."

Aside from their fab price (over 40% off!), we love the real-time power readout on the front of the case of these earbuds, making it so much easier than pulling out your phone and swiping to find out how much charge is left.

They also have multiple sound modes to pick from. Nearly 8,000 five-star fans can't be wrong, right?
