Accutire Digital Tire Pressure Gauge (5-150 psi) psi/bar/kPa/kg-cm2 (Black)

Great product. Easy to use, easy to read. Finally, a tire pressure gauge that I can like.

Tire pressure gauges are about as unsexy a product as you can think of, but this one comes across as a top-notch example of industrial design. Its appearance is just as attractive when it’s in your hand as it is in its Amazon page photos. And in the best form-follows-function Bauhaus tradition, it invites you to hold it in a way that makes testing your tire pressures a simple, one-touch operation. Unlike some mechanical gauges I’ve had in the past, it’s easy to get a reliable reading with this digital gauge on the first try. Simply remove your tire’s valve cover, push the gauge's start button, then firmly press the sensor straight ahead onto the valve. (Don’t come at it from an angle.) In a fraction of a second it will get a reading and not let additional air escape. That reading will be to the nearest tenth of a pound. I believe its accuracy is to two tenths, and that’s plenty accurate enough. Going digital is such a nice change from mechanical sensors, which from my experience anyway would start the valve hissing with escaped air when trying to get a solid fit, and then hiss some more when removing the sensor. And mechanical gauges, even the fancy brass one I used to own, are notoriously unreliable. This little beauty is featherweight and doesn’t get dirty when you check your tire pressures, so it can live in your glove compartment. If you forget to turn it off, it will turn itself off after 15 seconds. The battery should last a year. And for the quality you get, the price is a bargain. If over time my experience with this product causes me to re-evaluate it, I’ll update this review. But so far so good! And one more tip: Go to Big O or another tire specialist and pay the $10 or so they charge to fill your tires to their recommended pressures (see the sticker inside the driver's door) using nitrogen gas. Unlike regular air, which tends to “bleed” from the tire over time, the nitrogen will stay put. Racing teams have known this for years and always use nitrogen. And now it’s available to you and me. My nitrogen filled tires have gone a year without losing more than a pound of pressure!

Surprisingly easy to use and accurate. Certainly far superior to a mechanical gauge.

No complaints here, seems to be good quality! Material is a bit cheap but for the price it's too new expected, but already it works well

Easy to use and very accurate.

I have had other Accutire tire pressure gauges that worked well, and this one does, too. Would purchase again in needed.

I was pleasantly suprised that gauge was accurate on the pressure reading. I read some of the negative reviews and that was an idsue with some folks but I went ahead and ordered it anyway. The display can be seen clearly, plus is nice and bright. The gauge is compact enough to fit in the center console of my truck.

I bought both the Accutire model MS-4350B and the Accutire model MS-4021B and I put my thoughts for each below. MS-4021B The MS-4021B has a nice looking, easy-to-read, red-LED digital display (not LCD as in the Product Description) and can measure tire pressure from 5 to 150 psi. The gauge is very straight forward and is easy to use. I find the grip of the gauge a bit awkward and it is the reason for the four-star rating. The statement in the Product Description “What's more, the included lithium battery will never need to be recharged or replaced.” is not accurate. The back of the package card indicates the gauge uses three replaceable LR44 batteries and provides instructions on how to replace them (and as one reviewer mentioned there is also a CR2032 battery under the LED display that is not supposed to be replaced by the consumer). That means once the CR2032 battery is depleted, the gauge is trash. MS-4350B The MS-430B gauge has a blue-backlit LCD digital display and can measure tire pressure from 5 to 99 psi (less than the 150 psi the MS-4021B can measure). This gauge uses 2 replaceable CR2032 batteries. (I don’t know if there is one under the display like in the MS-4021B.) The grip design is very nice with a place for me to place my thumb and press the gauge into the tire valve stem. I would not measure the air pressure as depicted in one of the product pictures (where the man is holding the gauge underhanded, against the tire’s valve stem). I put my thumb on the three horizontal lines above the flashlight button (round button in the center). The gauge can be set to remember the recommended tire pressure but I don’t find that feature useful. I can remember the tire pressure for both front and back tires is supposed to be 33 psi and if I can’t it’s in the door jamb. The MS-4350B has these features the MS-4021B does not have: Ability to set recommended tire pressure for front and back tires. A beep sound when tire pressure has been read. One LED flashlight Tire Pressure Readings When measuring the tire air pressure, I had no trouble with getting good seal with both gauges. The readings were very close, with only one-half pound difference. The MS-4350B read 33.5 psi and the MS-4021B read 33 psi. Both displays are easy to read, one is red LED and the other is backlit LCD. LED displays tend to be more power hungry than LCD displays. Final Thoughts I’m not sure how significant a one-half pound difference is; I like both gauges. I can recommend both but I prefer the MS-4350B. The MS-4350B has the grip and feel I like and it uses replaceable CR2032 batteries. I like the idea of the one-LED flashlight but I’m not sure how useful that will be…but I still like that it’s there. Both are made in China. Just a comment about the packaging: The MS-4350B is packaged in a sealed plastic and I had to use a box cutter to open it effectively eliminating the possibility of using it to store the gauge and instruction pamphlet when not in use. I really don’t like this type of packaging.

El general facil de usar solo es preionar un boton y el chequeo. Llevo unos meses con el la pila sigue igual funcionando y se ve de buen calidad a precio accesible.

This gauge is durable, easy to use, and easy to keep handy in a glovebox or door pocket. Reads accurately when tested against a calibrated air gauge. Still running on the original battery after 3+ years of monthly use.

This fortunately reads psi. It reads the same as another gauge I have and agrees with the car's TPMS so all three must be correct. I have an old version of this gauge from probably 20 years ago and it still works on the original battery. It's very easy to use and is highly recommended.

Accurate as expected

Excelente producto. Se ve claro, es preciso. Solamente a veces la valvulares negra como que si se afloja y se debe de apretar antes de medir. Para que la medición sea correcta se debe de medir en frio. Entonces carga las llantas a 6 psi más de lo que indica el manual. De ahí ya lo dejas la noche y en la mañana antes de partir lo dejas. Manejar con las llantas bajas causa el mayor desgaste y que exploten en carretera.
