모든 자동차 소유자는 툴킷에 최고의 타이어 공기압 게이지 중 하나를 포함해야 합니다. 타이어에 공기압을 적절하게 유지하면 타이어가 고르게 마모되고 가능한 최고의 연비를 얻을 수 있습니다. 값비싼 타이어를 너무 빨리 교체하지 않아도 되고 타이어를 채울 때마다 비용을 절약할 수 있는 작은 투자입니다.
미국 환경 보호국(US Environmental Protection Agency)에 따르면 평균 타이어 공기압이 1.8 PSI(전면 1.1 PSI, 후면 2.8 PSI) 부족하며 공기압이 너무 낮을 때마다 연비는 0.4%, 평균 0.7% 감소합니다. . 많이 들리지 않습니까? 이는 갤런당 3센트, 10갤런 주유에 30센트, 일반 운전자의 경우 연간 168달러를 지불하는 것과 같습니다. 따라서 얻을 수 있는 최고의 타이어 게이지(및 훌륭한 공기 주입기)에 20달러를 지출하는 것이 훨씬 더 쉬워집니다. 특히 한 번만 구매하면 됩니다.
몇 파운드 낮은 타이어는 눈으로 볼 수 없습니다. 래디얼 타이어는 공기 중 약 5 PSI가 떨어질 때까지 낮아 보이지 않기 때문입니다. 지갑에 움푹 들어간 곳. 그리고 눈치채지 못하셨다면 휘발유뿐만 아니라 타이어 가격도 오르고 타이어 공기압이 낮아 타이어가 더 빨리 닳게 됩니다. 펑크가 나거나 타이어가 펑크날 가능성이 훨씬 더 높습니다.
타이어 공기압 게이지는 연필형, 아날로그(다이얼)형, 디지털형이 있으며 모두 장단점이 있습니다. 고품질 연필 스타일 게이지는 비용이 많이 들지 않고 수십 년 동안 지속되지만 일반적으로 2.0 PSI 증분으로 읽기 어렵고 가장 정확하지 않습니다. 보정된 다이얼 게이지는 이 가격대에서 가장 정확하고(레이스 팀은 수백 달러에 달하는 초정밀 디지털 게이지를 사용함) 일반적으로 가장 비쌉니다. 그들은 종종 호스가 부착되어 있으므로 타이어 밸브에 얼굴을 가까이 대지 않아도 됩니다. 일부는 편리한 디플레이터가 내장되어 있습니다. 디지털 타이어 게이지는 사용하기 쉽고 읽기가 가장 쉽지만 일반적으로 인증된 보정이 있는 게이지는 더 많은 비용을 지불해야 합니다. 저렴한 제품은 몇 가지 다른 공장에서 몇 가지 스타일로 만든 다음 다른 브랜드로 약간의 외관을 변경하여 판매되는 상품입니다. 둘 중 하나를 선택해야 하는 진짜 이유가 있는지 확인하기 위해 더 많은 테스트를 진행할 예정입니다.
아래에서 최고의 타이어 게이지를 선택하고 사용 및 적절한 타이어 공기압에 대한 많은 정보는 목차를 참조하십시오.
두 곳에서 회전하는 긴 편조 호스와 읽기 쉬운 다이얼이 최고의 선택입니다.
7개의 압력 게이지를 테스트하고 편집자의 경험을 바탕으로 편집자의 선택은 Rhino USA 75 PSI 헤비 듀티 타이어 압력 게이지입니다. 16.75인치 편조 호스 및 척 어셈블리, 0.3인치 보호 고무 범퍼가 있는 2.0인치 야광 고대비 다이얼 및 견고한 황동 하드웨어가 특징입니다. ANSI B40.1 표준으로 보정되었지만 범위 전체에서 허용 가능한 오류를 알려주는 등급을 나열하지 않았습니다. 테스트에서 다른 게이지의 1.0 PSI 이내인 것으로 나타났습니다.
이것은 우리가 시도한 가장 다재다능한 게이지로, 척과 다이얼 본체 모두에 스위블 연결이 있습니다. 따라서 밸브 스템의 한쪽 끝을 쉽게 얻을 수 있고 다른 쪽 끝은 읽기에 편리합니다. 많은 다이얼 게이지와 마찬가지로 공기압 릴리프 밸브가 매우 느린 경우 디플레이터 역할을 하는 공기압 릴리프 밸브를 사용하여 타이어에서 제거한 후 판독값을 유지합니다. 그러나 우리 목록에서 가장 큰 타이어 게이지이므로 글러브 박스에 끼우는 것이 훨씬 덜 편리합니다. 얼굴을 긁힘으로부터 보호하기 위한 졸라매는 끈 가방과 원하는 경우 스티커 및 데칼 패키지가 함께 제공됩니다. Rhino USA 헤비 듀티 타이어 공기압 게이지는 92%의 긍정적인 평가와 4,600개 이상의 리뷰를 받았습니다.
우리가 편조 금속 호스를 받는 동안 Rhino USA는 장기적으로 천이 꼬일 가능성이 적기 때문에 우리가 선호하는 편조 천 커버 호스로 전환했습니다.
Rhino USA는 모든 제품에 대해 번거롭지 않은 무제한 평생 보증을 제공합니다. Rhino 웹사이트에는 수신자 부담 고객 서비스 번호와 이메일이 있으며 캘리포니아 Murrieta 사무실에서 고객을 환영합니다. 우리가 익명으로 전화를 걸었을 때, 누군가가 첫 번째 벨을 들고 우리의 모든 질문에 대답했고, 아무 문제가 없는데도 무료로 게이지를 교체해 주겠다고 제안했습니다.
우리가 에어 게이지에 돈을 썼을 때, 그것은 Dill에 있었습니다.
우리는 많은 타이어 게이지가 실제로는 동일한 해양 공장에서 제조된 동일한 제품이며 이름과 색상이 다를 수 있음을 발견했습니다. Dill은 미국에서 자체적으로 만들고 무게가 거의 0.5파운드에 달한다는 사실이 일회용 플라스틱 조각이 아니라는 것을 말해줍니다. 직선 또는 30° 각도로 판독되는 이중 풋 게이지는 불편하게 배치된 밸브에 접근하는 데 매우 유용하며, 우리의 경험상 대부분 밸브입니다. 트럭 타이어 등급이며 플라스틱 게이지에서 2PSI 단위로 20~120PSI를 읽습니다. 그것의 유일한 플라스틱 부분이고 나머지는 단단한 금속입니다. 범위의 하이 엔드가 필요하지 않은 경우 5 PSI까지 읽고 50 PSI까지 읽을 수 있는 더 정확한 연필 게이지가 있습니다. 아래에 있는 항목 중 하나에 대한 우리의 선택을 참조하십시오.
우리는 AutoGuide Garage에 약 6개의 타이어 공기압 게이지를 가지고 있으며 대부분의 일상적인 필요를 위해 Dill에 도달하게 됩니다. 이 금속 덩어리를 잡는 것은 매우 만족스럽고 사용하기가 더 쉬울 수 없습니다. 다이얼 게이지는 연필 스타일보다 더 정확하고 읽기 쉬운 경향이 있기 때문에 최고의 자리를 만들지 못합니다. 우리의 최고의 선택은 다른 테스트에서 많이 사용하는 내장 디플레이터와 함께 제공되지만 귀하에게 적용되지 않는 경우 Dill 공기압 게이지는 평생 동안 필요한 유일한 것일 것입니다.
이 에어 게이지는 83%의 긍정적인 평가를 받았지만 26개의 리뷰만 있기 때문에 일반적으로 권장 사항에 포함될 자격이 없습니다. 그러나 수천 명의 메카닉은 말할 것도 없고 이들에 대한 개인적인 경험에 따르면 실망하지 않을 것입니다.
Dill Air Controls Products는 1909년부터 미국에서 타이어 부품과 게이지를 제작해 왔으며 어떤 이유로든 $10 타이어 공기 게이지에 대한 고객 서비스가 필요한 경우 Dill 웹사이트에 800개의 번호가 있습니다(방문을 원할 경우 운전 경로도 제공됨). ) 노스캐롤라이나 주 옥스퍼드에 있는 본사 뿐만 아니라 팩스 번호 및 웹 양식. 타이어 게이지에 60일 보증이 있습니다.
Astro AI 게이지의 조명은 매우 밝지만 측정값을 얻으려면 여러 번 시도해야 할 수 있습니다.
AstroAI 디지털 타이어 공기압 게이지는 우리가 테스트한 최고의 디지털 게이지입니다. 밝은 조명과 정확한 판독 값은 동 가격대의 다른 게이지보다 우수합니다. 파란색 백라이트 LCD와 무광 마감 그립이 특징입니다. 가장 큰 특징은 밸브 스템을 쉽게 찾을 수 있도록 척 주위를 도는 밝은 LED입니다. 0.5 PSI 증분으로 읽으며 0-150 PSI, 0-10 BAR, 0-10 kgf/cm2 또는 0-1000 KPA에 대한 설정이 있습니다. 모든 기능, 켜기/끄기 전환 및 측정 단위에 단일 버튼을 사용합니다. 전원을 절약하기 위해 30~40초 후에 장치가 자동으로 꺼집니다. 교체할 수 없는 배터리*가 포함되어 있습니다.
이 게이지는 다른 게이지의 정격 0.5 PSI 이내이며 디스플레이를 쉽게 볼 수 있습니다. But it sometimes took several tries to get it to take a reading, and it was easy to hit the power button and lose our measurement. The blue light is very bright, but we’d rather have white for the chuck flashlight, and red (or anything but blue) for the gauge for the sake of preserving our vision at night. This gauge has over 48,000 reviews and a very good 89% positive rating.
AstroAI offers a 30-day guarantee and one-year warranty on their product. They have a toll-free number, local California number, and customer support email on their site, along with easy-to-find user manuals. Customers report that warranty service is easy to use.
* You could pry it open and replace the batteries, but it takes one CR2032 and three LR44 button cell batteries, and there are some plastic tabs it’s easy to break. If you’re not a fan of disposable culture, be prepared to do some gluing or use small screws during reassembly.
Quality construction and simple operation make the TireTek gauge a solid choice.
Of all the gauges we tested, only TireTek lists the grade of ANSI B40.1 calibration, Grade B, which is the highest standard for consumer and commercial gauges. That means it’s rated for 3% accuracy, or ±1.2 PSI, from 15 to 45 PSI. Other gauges might be as accurate, and others in the AutoGuide Garage performed equally well, but without publishing the grading, you have no way of knowing. If it was as convenient to use as our top pick, it would be in the running for the #1 spot on our list.
Like most mechanical dial tire pressure gauges, it holds pressure and it’s reading until you release a valve. This lets you measure on the tire, but without the need to get your face down close to the valve stem. The two-inch face is surrounded by the typical rubber drop guard, and the rest of the construction is steel and plated brass. The face glows in the dark, but you need to shine a bright light on it first, so it won’t work straight out of the glovebox. As 45-degree swiveling 5 mm chuck is more usable than a straight one, but it can be hard to get into some tight wheels. If you don’t have the room for our top pick, this is a good choice for accuracy and dependability, and it has an excellent 92% positive rating from over 5,500 reviews.
TireTek gauges have a 12 month warranty, which you can extend to a lifetime satisfaction warranty by registering your product on the TireTek site. There is a web form and customer service email, but no phone number.
Accutire has a great reputation but some usability issues.
Accutire makes a classic and well known digital tire gauge, used by thousands of people for years. But there have been a number of running changes to the MS-4021B model that make it hard to know what you’re getting. It has a very grippy butyl rubber handle that makes it easy to hold onto in wet or greasy conditions. The gauge reads in PSI only, from 5-150 PSI in 0.5 increments and is said to be accurate within 0.5 PSI. Accutire doesn’t list any standard for this claim, but they’re well known as an accurate gauge.
It uses a fixed, 45° angled head, which would generally be useful for a fixed head design, if it were easier to know if you were actually getting a reading. It turns on automatically when it detects pressure from the valve stem, but we found it seldom measured on the first try. We had to remove it, then press it down again and hold it until it displayed a pressure reading. Then, the dimly lit display would turn off after 10 seconds, and it’s not bright enough to read in direct sunlight. Previous versions have looked different, and some have had an on-off button. We’re not sure if our all-black version, as opposed to the typical black and gold, is a different model, but it has the same MS-4021B model number it’s had since 2014. Nevertheless, it has a good 84% positive rating and over 5,600 reviews.
The three LR44 button cell batteries are replaceable, but you need a JIS #1 (or #1 Phillips) bit for the tiny screw. Many common problems with the gauge can be solved by resetting it by removing and replacing the batteries. Four extra included valve stem caps are a nice touch, but there’s no way to store them.
Accutire is a brand of Measurement, Limited, Inc., of Newport News, Virginia, which make tire pressure gauges for Michelin, among many other products. Accutire more or less has a website, where with a little work you can find an email address, local Virginia phone number, and web form. We were sent directly to voicemail when we called. There is a five-year warranty on the MS-4021B tire pressure gauge, but Accutire requires you return defective gauges at your expense, which is probably not worth it for a product in this price range.
JACO is a top-quality product but falls down the list with a lack of customer service.
JACO produces a high-quality mechanical dial gauge similar to Rhino, and at about the same price. The ElitePro tire pressure gauge is calibrated to ANSI B40.1 standard and promises ±1.5% accuracy without having to rely on batteries. Manufactured with premium heavy duty components, the gauge is surrounded by a rugged, gear-style guard and has a flexible 10 inch rubberized no-leak air hose. There is a built-in bleeder valve to reduce pressure in overinflated tires, while the 360-degree chuck makes it easy to access your valve stems.
The two-inch dial reads up to 100 PSI and glows in the dark, while readings are locked in place until the pressure reset button is pushed. We like the high-contrast, two-inch dial for readability. It has a terrific 93% positive rating from 5,700 reviews.
JACO Superior Products offers a 30 day money back satisfaction guarantee and lifetime warranty on their product ElitePro gauge. When we called them, there was a message saying JACO didn’t have phone support “this week,” but we don’t know how old the message was. We’ll check back later to see if that changes, but for now there is just a web form and email on the site. This keeps the ElitePro out of contention for a top spot on our list, even if functionally it’s very competitive.
It’s fair to call the Milton Pencil Gauge an automotive icon.
If you like cars, this is one of those tools that you should own at least once in your life. Milton has sold untold millions of their classic pencil gauge over the years, and with good reason. This US-made, plated brass single chuck head pencil tire pressure gauge is just about the cheapest way to get the job done reliably.
This old standard measures 5-50 PSI in 1 PSI increments on two faces of the gauge, and 40-350 kPa in 10 kPa increments on the other. Milton Industries doesn’t state how accurate the gauge is, but ±1 PSI is probably a safe bet, which puts it in the middle for accuracy. The head is at a good angle for taking readings, shallower than the 45° on most other gauges. You’ll need to check your measurement two or three times to be sure you got full pressure into the gauge, until you get used to it. The markings are legible but small, and exposure to any solvent, like brake cleaner, will remove them. The Milton S-291 Passenger Tire Gauge has a very good 90% positive rating across almost 4,500 reviews.
We wouldn’t expect most people to feel compelled to make a warranty claim for a tire gauge you can pick up almost anywhere for under $10, but Milton Industries has a 15-day money back satisfaction guarantee, and one-year limited warranty on defects. You can submit the warranty claim through a web form on the Milton site, and there is a toll-free number and other web forms on the Milton site. You can also register your gauge with Milton, if you wish.
This wouldn’t be a “Best” list without a Longacre gauge.
You aren’t going to see a Longacre in most garages, or even tire shops, but if you need the most accurate and legible tire gauge this side of the aerospace industry, there aren’t too many other choices. Where you will find them is in places that build and race cars.
This massive USA-made gauge sports a 4.5 inch face, and is marked in 0.5 PSI increments from 0-60, which makes sense when you consider its lab-quality 0.5% (0.25 PSI) accuracy for the entire range of the gauge, or ASME B40.1 Grade 2A. It has a high grade 17-inch hose and comes with both a straight 45° swivel angle chuck and a swivel ball chuck, not to mention a padded metal carrying case. It also has dual pressure release buttons to make it useful for controlled deflating.
This is complete overkill for any commuter car and you could buy a case of any of the other gauges on our list for less than the Longacre Pro Precision, but it’s vital equipment for places like race shops where every half a PSI matters. You’re also not going to find many reviews for a product like this, although those it has are 100% positive. Their products lower down the product stack are all in the 92-95% positive range, with thousands of reviews.
We’re not sure why a premium product like this only has a one-year warranty, other than they make expect them to have hard use trackside. They do offer a repair service and are very easy to contact, with multiple toll-free and local Indiana phone numbers, emails, and web forms on their site. They answered our call on the first ring, and answered our questions immediately.
Sometimes less pressure is good, as long as it’s the right amount. Photo credit:David Traver Adolphus / AutoGuide
Often overlooked and even sometimes forgotten, your car’s tire pressure is an important factor in making sure your car runs optimally. These days, most modern vehicles come equipped with Tire Pressure Monitoring Systems (TPMS), which takes the guesswork out of wondering whether your car’s tire pressure is low or not. But what if your car doesn’t have TPMS? And if it does, are there still things you should know?
You may be surprised by how great of an effect your car’s tire pressure has on your vehicle’s performance. In fact, if you’ve noticed that your gas mileage has gone down a few MPG, it’s likely attributed to your car’s tires.

Even if your car is equipped with TPMS, you will want to know the recommended tire pressure for your specific vehicle. Typically, there is a sticker found inside the driver’s side door that will list the recommended tire pressure. This figure is normally indicated in PSI, which stands for pounds per square inch of air. In addition, your tire’s maximum air pressure will be labeled on the tire’s sidewall. That figure is the maximum PSI the tire can safely hold. In other words, don’t inflate your tires beyond the number found on the sidewall.
If you are not able to locate a sticker on the inside of your driver’s side door, refer to the owner’s manual to determine the recommended tire pressure for your car.
Keep in mind that the recommended tire pressure values could be different between your front and rear tires. Make sure you’re checking both front and rear values when you’re determining whether your tires are properly inflated.

There’s a reason why vehicles have recommended tire pressures. Proper inflation of your car’s tires not only ensures it’s comfortable to drive and ride in, but it can also affect your fuel economy. More importantly, they ensure your tires are wearing out uniformly, extending the life of your tires.
Overinflating or underinflating your tires could have adverse effects on its performance. Not only do underinflated tires appear flatter, they have increased surface contact with the road. If driven over a long period of time, that contact can result in premature tire wear. Underinflation also has a direct effect on the car’s fuel economy.
Overinflating your tires with too much air can cause increased rigidity and stiffness, resulting in a harsher ride. Contact with the road is typically increased around the center area of the tire when it is overinflated, causing additional wear in the center. If you notice the sides or outer sections of your car’s tires are less worn out than the center, it’s a good chance they’re overinflated.
Checking your car’s tire pressure is a fairly straightforward and simple task. The easiest method is to use a tire pressure gauge that you can purchase online or at any automotive parts store for cheap. It’s normally recommended to check your car’s tire pressure levels when the tires are cold, or after the vehicle has been parked for at least three hours. Since friction causes heat, and heat increases tire pressure, doing a check after driving will likely give you an inaccurate figure. The recommended tire pressures you find in either the decal inside your driver’s side door or in your owner’s manual refers to the tire pressure before you start driving.
Using the tire pressure gauge, remove your valve stem cap and simply place the gauge on the stem with some pressure. A number will appear on the gauge, and it never hurts to check it two or even three times to make sure you have an accurate reading. Once you’ve checked the tire pressure on all four tires, make sure to replace the valve stem cap.
Avoid gauges like this one that don’t hold a reading when you remove them from the valve stem. Photo credit:David Traver Adolphus / AutoGuide.com
If you don’t own a tire gauge, nearly all public air compressors will have an integrated tire gauge. More modern units at gas stations may have digital readouts to show your tire pressure. If your tire is overinflated, you’ll want to let some air out to get it back to the optimal PSI range. Make sure to check it periodically while you’re letting air out, so you don’t end up underinflating your tires.
With tire pressure monitoring (TPMS) required in new vehicles, many people don’t think about tire pressure unless the light illuminates. Or maybe you go with the “eye test,” where you just look and gauge whether your tire is flat or not. But a TMPS light won’t go on until your tires are about 20% low, far below the threshold to cost you gas money and wear out your tires.
Even in modern vehicles, you should check your tires (and oil!) at least once a week. It only takes a couple of minutes and is an easy way to stop problems before they start, and get to know your car better. Every time you drive, you should take 11 seconds to walk around your vehicle, especially if you’re taking a long trip. Then you can whip out your handy gauge if something looks off.
If you keep a tire gauge in your car, why not just do a quick check while you’re gassing up? It’s something productive to do with that time and could go a long way in making sure your tires last as long as they should.
Tire gauges are easy to use, regardless of whether they’re digital, dial, or pencil. Pencil tire gauges are typically compact and are a long thin tube with a chuck on one end to connect to the valve stem of your tire. As soon as you press it on and it gets air pressure from the tire, a plastic rod will extend from the gauge to show your PSI. If you’re using a pencil tire gauge, we recommended checking the tire pressure two or three times to make sure you have an accurate reading. When you’re done, just push the rod back in. It should go in with almost no resistance, which also makes it easy to change by accident before you can look at it. Some pencil tire gauges will also allow you to let air out of your tire by putting the opposite end into the valve stem.
While they do cost a bit more than a conventional tire gauge, digital tire gauges are more reading and are easier to use. Some of them turn on automatically, while others have an on-off or multifunction button. Then, all you have to do is turn on the gauge and place it on the valve stem to get a PSI reading. But since they are digital, they’ll require batteries so always keep a spare set handy. If you’re not using it every day, and it isn’t alternately baking and freezing in your car, you should get at least three to five years out of a set of button batteries. A backlit screen is very handy for use under a dark car or at night, but they can wash out in sunlight.
We like dial gauges for everyday use. You know when you have a reading, because the indicator needle jumps when the gauge is pressurized. They have several advantages. Most of them hold pressure until you release it, so you have plenty of time to look at the number. They also tend to be large and easy to read, with two inch or larger dials. Many are glow in the dark and they don’t need batteries, but they need light first if you want them to glow. Dial gauges can be very accurate and there’s a calibration standard—look for those that say they meet ANSI B40.1, which is the highest standard of accuracy for consumer products.
Wed don’t recommend driving your car for an extended period of time with low tire pressure. If your vehicle is equipped with TPMS and the light is on, you’ll want to address the issue as soon as possible. Low tire pressure not only results in uneven wear on the tire, it increases the risk of getting a flat or even a blowout.
