The Slime Digital Tire Gauge is a useful tool that helps to determine whether the tire pressure of your vehicle is in the right setting. Regular monitoring of the pressure of your tires is important for several reasons; for one, correct tire pressure helps prevent accidents, because when the tire is under-inflated, it does not perform as it should, making it very difficult to control the vehicle. When the air pressure in a tire is low, it also does not respond correctly when the brakes are applied.
Tires function well when the tire pressure is in the correct setting, and that also helps the vehicle to perform well on fuel usage, too. Therefore, it is very important that you check the pressure of your tires once a month and also before setting off on a long road trip. You can easily get that done when you have your own tire gauge, therefore, purchasing a suitable tire gauge is just a small investment that will ensure a safe drive, and also help extend the life of your tires.
It is important to remember that the pressure in tires drops even if the car has not been used regularly, and even when they have been removed from the vehicle. As well, tires lose pressure during cold weather.
While purchasing a tire gauge for your vehicle is a good practice, it is also good to do some research on your own to determine which Slime digital tire gauge best suits your needs.

As Taylor Swift sang, “The devil’s in the details.” You might not think a simple thing like tire pressure is crucial to your vehicle’s operation, but it is. The only way to truly track that pressure is with the best tire pressure gauge.
Maintaining the correct air pressure across all tires enables even distribution of weight. Doing this gives you the most stability and ensures uniform tire degradation. With one or more tires unevenly worn, underinflated, or overinflated, there can be a significant decrease in performance when attempting to corner, stop, or evade an accident. The importance of a tire pressure gauge speaks for itself.
To help you choose the best tire pressure gauge, we performed several hands-on tests (which we’ll go over later in the article). We tested accuracy, environmental conditions, and durability. Keep reading to find out what we discovered.

Types of Tire Pressure GaugesShoppers will find three standard types of pressure gauges: stick/pencil, analog/dial, and digital. The latter two can also attach to pneumatic hoses for inflating tires without detaching the gauge. But since they require you to have a pneumatic/compressor system at your disposal, they aren’t included in this article.
Stick/Pencil GaugeThe stick/pencil-type gauge is a traditional, old-school device that has been around for decades. It’s an analog tool made of a metal outer shell attached to a chuck and an inner measuring rod made of plastic or metal.
When applying pressure through the chuck valve, the inner rod extends according to the pounds per square inch (psi). Whatever length the rod extends to before it meets the outer shell will indicate the tire’s pressure. It’s basic and straightforward, which is why it has endured so long.
Analog/Dial GaugeA dial or analog gauge has a clocklike face with a needle that points to the correct psi. Some are small and compact, and others have features like dual-scale dials or extension hoses. When attaching the gauge valve to the tire, the needle should rise quickly to the correct pressure and stay there until you hit the reset button (bleeder valve), which releases the captured air.
In general, these types of gauges are easier to read than stick versions. They are simple to use and reasonably compact but tend to be a little pricer than stick gauges.
Digital GaugeLike a digital watch or calculator, a digital gauge has an LCD that relays the pressure reading. Digital gauges are usually the most accurate of all versions and can read pressure to ⅒ of a psi. The displays feature LED backlights, which come in handy for low-light situations.
The downside to digital models is that they tend to be a little more expensive and depend on batteries to operate. If you’re not someone who regularly checks the batteries in your electronic devices, this could be a problem. Low batteries also can cause faulty readings.
What to Consider When Choosing the Best Tire Pressure GaugeThere are several factors to keep in mind when choosing the best tire pressure gauge, including storage since it’s important to keep the gauge somewhere easily accessible. Price is another consideration. But the most vital considerations should focus on suitability, so make certain the pressure gauge has the right features for your specific needs and vehicle type. Someone commuting to work in a busy city daily has different needs than a retired driver who enjoys using his heavy pickup for off-road excursions.
Size and WeightIt’s generally better to keep your gauge somewhere other than your glove box since extreme temperatures—particularly the cold—can affect its function. However, if you plan to keep one there, a compact, light gauge is an ideal choice. Gauges can vary dramatically in size and weight, with some small models weighing just a couple of ounces and other models with additional bells and whistles weighing half a pound or more.
Vehicle TypeDepending on vehicle size and weight class, the valve on the tire might differ from vehicle to vehicle. Of the three major tire valve types, the most common are tubeless rubber snap-ins. These are for use on standard-size cars, minivans, and light-duty trailers. High-pressure tubeless snap-ins are for use on medium- to heavy-duty trucks. The third valve type is a high-pressure metal clamp-in valve used in vehicles that might exceed 130-mph speeds with tire pressure as high as 200 psi. Gauges that clamp onto the valve directly are recommended for this type of valve.
Check valve location on the tires and determine how difficult it is to reach the valve. You could need an extension hose if the valve is in an awkward space. Keep in mind that an extension hose requires two hands to operate.
Measurement RangesMeasurement ranges among gauges can vary. Some stick versions only have a range of up to 50 psi, which is not enough to check the higher pressure spare that comes with most vehicles (typically 60 psi) but is sufficient for the installed tires. Digital gauges often have much wider ranges of 1 to 150 psi and can frequently give metric measurements as well, such as kPa, 1 kgf/cm2, and bars (see note below). These units all measure the same thing and simply depend on where you drive and where the vehicle and tires were manufactured.
Note: One psi equals 6.895 kilopascals (kPa), while1 kgf/cm² (kilogram-force per square centimeter) equals 98.0665 kPa, and 1 bar equals 100 kPa.
With standard-size vehicles like sedans, minivans, and light-duty trucks, a gauge that can read up to 60 psi will likely be sufficient. Having a broad-range gauge is good, but depending on how small the measurement etchings are, as with stick gauges, you might struggle to get an accurate reading.
Accuracy GradeMost gauges have an accuracy of plus or minus 1 psi and are sufficient for most car drivers today. Only digital gauges can display greater accuracy to plus or minus 0.1 or 0.2 psi.
It’s important to check your new gauge for consistency and accuracy when you first unbox it. To do so, simply check the pressure on your tire 10 times in a row. If the reading varies significantly from test to test, instead of showing a constant reading all 10 times, return it and choose a different model.
Built-In Air Compressor/InflatorWhen purchasing a gauge, a nice feature to have included is a built-in compressor/inflator. On average, while more expensive than a simple pressure gauge, it can be a big time-saver if you need to pump up an underinflated tire. Make sure you choose a compressor that reaches the required psi for your tires.
Since a compressor/inflator is much bigger and bulkier than a basic gauge, storage is a factor to keep in mind. Additional factors to consider include a power source for the unit and whether it will plug into the car’s 12-volt jack or features a cordless battery. Cordless versions are optimal if you have other tools that use the same batteries and consistently keep charged packs.
UsabilityQuick, reliable readings are essential, so don’t overlook an easy-to-read display, especially in low-light conditions. Digital options include LED, light-up, or backlit displays that will work in the dark. Many analog dials also feature glow-in-the-dark displays that work almost as well as their digital counterpart, without the need for batteries.
Dropping a gauge too often can result in damage. Ergonomic grips can help reduce damage from dropping by enabling a firm hold, even while wearing winter gloves or with sweaty palms in the hot sun. Consider storing your tire pressure gauge in a protective case to help guard the device for the long haul.
Additional FeaturesThe ability to determine whether your tires are properly inflated is a basic requirement for all gauges. However, many manufacturers also offer a few emergency tools to sweeten the deal. These can include 360-degree swivel chucks, lifetime warranties, different types of pressure measurements (psi and kPa, for example), and even auto-shutoff for some digital models.
Many gauges also feature built-in bleeder valves to let off excess pressure in case of overinflated tires, eliminating the need to detach the unit while you deflate it. Some devices are feature-rich, with built-in emergency tools, including flashlights, seat-belt cutters, safety hammers, and lights.
Our Top PicksThat’s a lot of information on the best tire inflators, and there might be a bit of pressure building when it comes to shopping. After extensive testing, we compiled the following list of products as a reference. Be sure to keep the top considerations in mind when comparing these products.

Rhino USA builds this analog gauge from solid, high-grade metals, and it doesn’t require batteries. The rubber, ergonomic grip gives adequate protection from damage and makes the gauge easier to handle during inclement weather, while its glow-in-the-dark dial allows users to see pressure readings even in low-light scenarios. Round it off with a 360-degree swivel chuck and a “no-leak” braided air hose, and there are plenty of valuable features in an analog package.
During testing, we really enjoyed the hose and swiveling chuck, as it was clear that this gauge would be easy to use in any situation. We also liked that this gauge locks the pressure reading in place until the user can check it. The solid brass construction was truly durable, and the braided hose was plenty flexible for our needs. If there is any complaint, it’s that you have to use two hands to take advantage of the hose. But since the pressure locks in place, it’s not a deal-breaker.

The best tire pressure gauge should be straightforward and easy to use, and the Vondior Tire Pressure Gauge fits the bill. This heavy-duty, single-function tool features a glow-in-the-dark analog dial that helps the user see in low-light situations without having to rely on battery power. The protective rubber casing is ergonomic for comfort and conveniently offers some protection against drops. And at just 5 inches long, it fits easily in the palm of your hand.
Additional features include a bleeder valve for reducing overinflation and a swivel chuck for 360-degree connections to reach valves in various positions. For the price, it’s a solid deal that should work for most drivers’ needs.
At first, this was our favorite gauge in the bunch. It had a mechanical, trustworthy feel that we really enjoyed. The analog gauge was easy to use, and we liked that it held the pressure reading until released with the bleeder valve. And the swiveling chuck was super convenient. But after a series of drops, the glass on the dial broke and this gauge consistently read 10 psi lower than the others, so take measures to avoid dropping it.

The Milton S-921 Single Chuck Tire Pressure Gauge offers simplicity in a sleek and useful tool. The compact design has been around for decades. Although it doesn’t have any fancy features, the gauge works well in cold weather and is nearly foolproof to use. This stick-type gauge costs less than other tire gauge types, and it provides measurements in psi and kPa. The display doesn’t glow in the dark, but this stick gauge is so easy to use that it takes little time to get a reading. It also takes up little space in your car, measuring only 8.1 by 1.2 by 1.1 inches.
For the price, it’s hard to beat a reliable stick gauge like this one. We found that it was consistent and accurate, and unlike some other stick gauges that retract the stick after releasing the pressure, this one doesn’t. This allowed us to check the reading without bending over or kneeling. The only issue we found is that you’ll want to keep the stick as clean as possible, as gunk or dirt can affect the reading.

With its lightweight, compact barbell design, the Makita DMP180ZX 18V LXT Lithium-Ion Inflator is handy to cart around. The pressure gauge display is backlit and conveniently shuts off as soon as it reaches the preset desired pressure. A built-in LED light on the front of the inflator illuminates the work area. Furthermore, those who own other Makita tools can use the 18V batteries they already own for the inflator without purchasing a separate one. After measuring pressure, users can add air to a tire quickly with this portable inflator.
Testing this compressor against the other models on the list almost felt unfair, as it’s capable of so much more. It has a built-in worklight, it can obviously inflate a tire (and it has a programmable max pressure), and it comes with accessories like a sports ball needle and inflatable toy nozzle. It’s very easy to use, and the gauge is reasonably accurate within 0.5 psi. But, there are downsides: The digital gauge requires a charged battery no matter what, and it’s much too large for a glove box.

For its usability, affordability, and durability, the Rhino USA Heavy Duty Tire Pressure Gauge reigned supreme. But for those who might need a few more features, the Makita DMP180ZX Inflator has what it takes to not only check the pressure but also boost it when necessary.
How We Tested the Best Tire Pressure GaugesIn order to provide some honest feedback about these tire pressure gauges, we tested each one several times. The tests included some environmental conditions and some shock testing, which most passed quite easily. And since the old off-roader we used doesn’t have built-in tire pressure monitoring, it was the perfect test subject.
First, we tested each gauge at room temperature. We brought each gauge to a spare tire and checked the readings 10 times. Obviously, after checking 10 times, the pressure would drop, but we wanted to check for consistency. Then, we put all of the gauges in the refrigerator for an hour to simulate how they might work in cold temperatures. Finally, we left them out in the hot afternoon sun and repeated the test, simulating how they might work if left in a hot car.
The toughest test was the waist-high drop. We held each of these tire pressure gauges (except for the Makita) at waist height and dropped them five times. After dropping them five times, we took readings from the tire. Almost all did well, except for the Vondior, which we describe above.
Tips for Using a Tire Pressure GaugeStart with finding out your vehicle’s optimal psi by checking the driver’s side door for a sticker that lists the information. Don’t go by the recommendation on the tire if you can avoid it. Next, remove the caps from the valve stems on your tires, and press the gauge nozzle tightly to the tire valve’s tip. Some air escaping the tire is normal, but it shouldn’t be excessive. There should only be a brief second or two of hissing. Read the gauge according to your individual tool’s operating instructions, then switch it off or reset it when finished. Inflate the tire or release some air according to what you find. After inflation, replace the caps on the tire valves.
When considering a new device or wondering if you’ve got the best tire pressure gauge for your vehicle, look over the answers to these commonly asked questions below.
Q. Are tire pressure gauges accurate?Most analog gauges are accurate to plus or minus 1 psi, and digital ones are plus or minus 0.01 psi. Check a new gauge for consistency.
Q. How do I use a tire pressure gauge?Reset the gauge to zero. Press the nozzle/chuck firmly against the tire valve and hold for a second or two, and you should see the reading right away.
Q. How often should I check my tire pressure?On average, your tires lose about 1 psi per month. As a rule, it’s a good idea to check the pressure at least once a month, especially during the fall and winter months. And remember to check your spare.
Q. How do I know if my tires are properly inflated?Check the inside of your driver’s door for a sticker that should recommend the optimal pressure for each of the tires.
Maintaining the recommended tire pressure ensures ride comfort, agility and good traction. With a strong change in pressure, the effect of aquaplaning is observed, roughnesses in the road are felt, disk deformation and uneven wear of rubber often occur. A pressure gauge is a convenient and easy way to measure tire pressure yourself.

An automobile pressure gauge is a device that indicates the density of air inside a tire. The obtained physical measurements are displayed in bars or kgf/cm². The simplest mechanical type pressure gauge consists of a Bourdon tube, a body, a hose, an arrow and a fitting.
The principle of operation is that when air is injected, the Bourdon tube sets the pointer in motion. Being connected to the valve, air pressure acts on the brass tube, which tends to unbend, the other end acts on the rod, moving the arrow. The received data is displayed on an analog or digital display. nine0009
Automotive pressure gauges can be:
switch;
rack;
electronic.
Whatever the pressure gauge, they all have the same operating principle.
To measure from the valve, unscrew the cap and attach the pressure gauge. The result is displayed as numbers with tenths (on electronic models) or fixed with an arrow. In electronic pressure gauges, you need to press the "start" button. nine0009
Pressure is displayed in bar or atmosphere (1 bar = 0.98 atm.). Gauges made in the USA may also read in pounds per square inch (psi) - 1 psi = 0.068 bar.
Measurements with a pressure gauge must be carried out with the tires completely cold. If the vehicle has been driven, at least three hours must elapse after stopping. This recommendation is due to the fact that the pressure in the heated wheel will not be 15% higher than the actual value. In the cold season - 10% lower. nine0009
Checks should be regular, for new tires - 2 times a month or after each refueling, for worn tires - before each ride. Measurements are taken on an unloaded vehicle at the temperature at which it will be operated.

Pressure gauges are indispensable devices that measure the pressure of the working medium in pipelines, boilers, pumps, other equipment and apparatus. These devices are characterized by a simple principle of taking readings. To figure out how to measure pressure with a pressure gauge, no special training is required. Almost anyone who has been instructed can cope with this. However, there are certain points that need to be considered. nine0009
Today there are a large number of varieties of manometers. They have different designs and are suitable for different purposes. To measure the pressure of the working medium in pipelines and various equipment, the following types of instruments are most often used:
spring - the pressure is balanced by the force that occurs when the spring is deformed. The devices are simple in design, thanks to this, if necessary, it is not difficult to disassemble the pressure gauge for repairs; nine0009
membrane - the main functional element is the membrane, which is deformed under the pressure of the working medium, due to which a balancing force of elasticity arises;
piston - a piston with a load of a certain size is used to balance the pressure;
electrocontact - these devices are used in automatic control and alarm systems.
Measuring pressure is very simple if you understand the general principle of operation that is characteristic of all mechanical pressure gauges. The device has a balancing element (spring, piston, membrane, etc.), which perceives the load from the pressure of the working medium and deforms or moves under its influence. The counterbalancing element is placed inside the device body and has a mechanical connection with the pointer. Thus, the movement of the meter needle depends on the magnitude of the acting pressure. This value is displayed by an arrow on the scale of the device. nine0009
To get readings, just look at the pressure gauge. The arrow on it indicates on the scale the amount of pressure that is acting in the system at the moment. When the measured value changes, the pointer simultaneously moves along the scale by the corresponding value. This makes the measurement as convenient and affordable as possible for almost any person.
However, just looking at the device is not enough. In order to use the pressure gauge correctly, it is also necessary to have an idea of the measurement values that are indicated on the scale. nine0067 The most commonly used values are:
technical atmosphere. The value of the atmospheric pressure acting at the level of the World Ocean. One atmosphere corresponds to 1 kg/cm2;
the value of the water column. Corresponds to the hydrostatic pressure of a column of normal density water 1 mm high at 4 °C acting on a flat base. This unit is often used in hydraulic calculations; nine0009
bar is a technical value that roughly corresponds to 1 atmosphere and 10 m of water column. Often used in the characteristics of pumps, fittings, boilers, and other equipment;
pascal. SI unit of measure equal to 1 N/m2. A value of 0.1 MPa corresponds approximately to 1 atmosphere or 1 bar.
When measuring, you must also take into account the accuracy class of the device, which is indicated in its passport and on the scale (conventionally denoted by the letters KL or CL).
