Where to Find the


When the tire pressure monitoring system (commonly known as TPMS) light comes on, it’s most likely time to add some air to your tires. You can find the correct tire pressure (or PSI) in your car’s manual or in your doorjamb. It’s important to check your manufacturer’s recommendations before adding air as under or over-inflated tires can cause unnecessary wear and tear on your tires or poor fuel economy.

How to Check your Tire PSI

Commonly known as Tire Pressure, PSI stands for “per square inch”, and is the standard method for measuring a tire’s air pressure level. PSI is measured by the notches on a standard tire pressure gauge or with a number reading on digital gauges. By placing the gauge on the uncapped valve stem, you should get an instantaneous reading.


Check Your Doorjamb

An easy spot to refer to is on your driver’s side doorjamb. Here you will find the tire and loading information.

The easiest way to find your tire pressure is to read the doorjamb sticker on your driver's side.


Check Your Manual

You may have to flip through the pages, but the tire pressure table should be located in the tires and/or wheels section.

You can also find your vehicle's optimal tire pressure in your owner's manual.
