FAQs

How accurate is the slime tire pressure gauge? ›

This little tire Gauge works well and appears to be accurate. I tested accuracy by looking at the tire sensors on my car and then the Gauge. They are within . 5 psi which I would deem pretty accurate.

You'll get a more accurate reading if you check the pressure when the tires are cold, before the outside temperature rises and the tires are exposed to direct sunlight.

Most passenger cars' psi requirement will be between 30 to 35 psi, but several vehicles fall outside of that range and every vehicle will have specific requirements. Good tire air pressure ensures that tires wear evenly, provide a smooth ride, and increase fuel efficiency.

Jaco ElitePro Digital Tire Pressure Gauge

Jaco's ElitePro is a staple in the Car and Driver garage, and it's no surprise why: It's accurate, easy to use, and can take a beating in year after year of near-daily use.

Pros and Cons of Pencil/Stick Pressure Gauges

However, they are generally less accurate than Bourdon tube, diaphragm, or digital gauges and can be more difficult to read due to their small size and manual reading method.

To measure the pressure, remove the valve stem cap, place the tire gauge over the stem, and press down. Your gauge may be a “pencil” style, in which case a ruler will slide out to show the reading. Or you may have a digital gauge, which will provide a clear and more accurate reading which will appear on the screen.

So, when filling your tires, the recommended tire pressure is the best compromise between handling, comfort, fuel economy and safety. But it's certainly fine to go over the recommended inflation by a psi or two. And going over is always better than going under.

According to the AAA study, the average percentage difference between displayed and actual tire pressure was between 1.2% and -1.5%, depending on tire location.

1) You can check the air pressure in a tire with the gauge in question and then check the same tire with another gauge. If there is a significant difference in the readings (4 or more psi) between the two gauges one or both gauges may be inaccurate.

Where I can find the correct pressure for my tires? The recommended pressure can either be found in your car's operator manual or on a sticker on the inside of the post of the driver's door (see picture). This is the pressure at which the car handles, brakes, and operates most smoothly and safely.

Is 27 tire pressure too low? ›

To summarize, 32 - 35 is recommended; as a rule of thumb, make 28 a minimum, and if your tire pressure dips below 20, call vehicle support services and get your tire refilled immediately.

Don't trust the gauge on a gas station's air pump to be accurate. 2. Find out what the recommended pressure setting is for your car.

For a mechanical pressure gauge accuracy is defined as a percentage of the full-scale range. While requirements differ from one industry to another, the following are general guidelines: Test gauges and standards: 0.25% through 0.10% full scale accuracies. Critical processes: 0.5% full scale accuracy.

The digital type can look like any of the others, but it gives a digital reading of the pressure and is generally the most accurate. Some digital pressure gauges can also read the temperature. Each tire pressure gauge measures pressures in pounds per square inch (psi), kilopascals (kPa), or bars.

According to the AAA study, the average percentage difference between displayed and actual tire pressure was between 1.2% and -1.5%, depending on tire location.

Can Slime tire sealant be added to a tire to balance it? No. We do not recommend using Slime for this purpose.
