Simple gauges work well. Digital gauges are not necessary. Gauge prices range from a couple of dollars to $20. Tire gauges measure pounds per square inch (standard) or kilo Pascal’s (metric). To reset the pressure gauge, push the stem all the way in so that it is starting at zero.
Look at the writing on the side of your tires. The tire will have a maximum PSI or KPA number. This is the maximum pounds per square inch or kilo Pascal’s that your tires can handle. It is not advisable to fill your tires to this pressure. {“smallUrl”:“https://www. wikihow. com/images/thumb/7/7c/Check-and-Add-Air-to-Car-Tires-Step-2Bullet1. jpg/v4-460px-Check-and-Add-Air-to-Car-Tires-Step-2Bullet1. jpg”,“bigUrl”:"/images/thumb/7/7c/Check-and-Add-Air-to-Car-Tires-Step-2Bullet1. jpg/aid1184174-v4-728px-Check-and-Add-Air-to-Car-Tires-Step-2Bullet1. jpg",“smallWidth”:460,“smallHeight”:307,“bigWidth”:728,“bigHeight”:486,“licensing”:"<div class="mw-parser-output">

Allow the car to sit for 30 minutes to three hours before checking air in car tires for the most accurate reading. {“smallUrl”:“https://www. wikihow. com/images/thumb/c/c6/Check-and-Add-Air-to-Car-Tires-Step-3Bullet1. jpg/v4-460px-Check-and-Add-Air-to-Car-Tires-Step-3Bullet1. jpg”,“bigUrl”:"/images/thumb/c/c6/Check-and-Add-Air-to-Car-Tires-Step-3Bullet1. jpg/aid1184174-v4-728px-Check-and-Add-Air-to-Car-Tires-Step-3Bullet1. jpg",“smallWidth”:460,“smallHeight”:307,“bigWidth”:728,“bigHeight”:486,“licensing”:"<div class="mw-parser-output">

Some air may escape when you begin applying pressure. However, the air should stop leaking out once the pressure is increased and the gauge is evenly on the valve.
Standard gauges will blow out a stick. The notch on the stick where it stopped when blown out is the reading. Digital gauges will give a digital number as the reading.
The nozzle is on correctly when air stops leaking from the outside of the tire and is going inside of the tire.
Do not go over 5 PSI or KPA than is recommended for your tires. If the pressure is still too low, add another small burst of air and recheck the pressure. Continue the process until the PSI is met. If you put too much air in the tire, press against the pin in the valve stem with the gauge and let a small amount of air release from the tire. Recheck the tire pressure.
