How to Check Tire Pressure Without Gauge



Correct tire pressure is essential to the proper and efficient operation of your vehicle, just like wheel alignment and other routine maintenance. Not only does this optimize fuel economy, but it ensures you are kept safe.There are a variety of ways to check tire pressure, and using a tire pressure gauge is probably the easiest. Most modern cars also come with a tire pressure monitoring system (TPMS) as standard that measures pressure in real-time as you drive. Since it effectively works as an automatic tire pressure gauge, it’s easy to be lazy, but you should know how to check pressure yourself, because you never know when a sensor might stop working if it stops getting power from the battery due to an electrical problem.Of course, before you start fussing with gauges and other tools, you’ll need to know the correct PSI value for your specific setup. PSI is the measurement for tire pressure, denoting pounds per square inch. The correct figure for your vehicle can be found in the owner’s manual, but if you know how to find the PSI on a tire on the sidewall or on the label in the door jamb, you can check to see whether your tires are correctly inflated.
