How to check your tire air pressure: a step by step guide. To check the tire air pressure, make sure to start when your tires are cool. Take off your valve stem cap and place the pressure checker firmly over the stem until the sound of air stops coming out of it, then read it off your tool to compare it to the optimal pressure that is posted inside of the driver's side door jam.
Here’s What You’ll NeedChecking your tire pressure won’t take you more than a couple of minutes and there’s really just one thing that you will need, though there’s a second thing that is handy if you’re going to adjust your tire pressure:Tire pressure gauge - A dial or digital model works great, although any style will get the job done.
Air compressor - Only if you’re going to fill them, which you should be able to find at any gas station. Here are four steps for checking the air pressure of your tires. Step 1: Begin with the tires cold. Driving and braking heat your tires, which can inflate the air inside and skew your measurement higher.
When checking your tire pressure, use what is called “cold inflation” pressure (the number published by the tire manufacturers on the sticker on your driver’s side door jam).
Step 2: locate the recommended tire pressure. Open the driver’s side door, then locate the sticker affixed to the driver’s side door jam, just where the door closes in the frame, and press on the plastic to release it if necessary. Step 3: use a pressure gauge.
Pull off the valve stem cap by hand, and push the head of the tire pressure gauge down onto the top of the valve stem. Press in and continue to do this until the hiss stops, indicating the cap is creating a good seal. Step 4: adjust the tire pressure.
If the measured pressure is less than what’s on the door jamb sticker, it’s too low.
Add a little more air from a compressor at short intervals (no more than 5 seconds) and check with the gauge until you hit the optimum level. If it’s too high, press the button on your tire pressure tool until you lose a little air pressure.
Your tires can lose between one and two pounds per square inch (PSI) a month.
And, you will also lose an additional PSI for every 10 degrees that the ambient temperature drops, and the tire loses an additional PSI for every one-and-one half miles per hour you are going with each pass.
Driving a car or truck that is under-inflated also makes your fuel economy significantly worse, not just for the ride to work or school, but for the ride to the grocery store as well as on your longer trips.

What Are the Types of Tire Pressure Gauges?
Here are the main types of tire pressure gauges and how they differ: Gauge type What it does Best for Digital A digital pressure reading comes with an easy to view LCD display, usually a fairly precise number Accuracy/ease of reading in dark/low light Conditions/availability of a batteries for the device Analog/Dial You get a face on a clock, with a needle that rises with the tire pressure Easy to read and a very tough/durability device that can take more than it gives but are more bulky than the others Stick/Pencil This gauge is also fairly rudimentary in its use, and it basically works by pushing out a measruing stick or other indicating device, often through a metal tube Hard to read unless you are using it directly under a light, but the device is small, and portable for when on the go How often should you check your tire pressure?Your tires can lose between one and two pounds per square inch (PSI) a month.
And, you will also lose an additional PSI for every 10 degrees that the ambient temperature drops, and the tire loses an additional PSI for every one-and-one half miles per hour you are going with each pass.
So, how often is adequate?
Experts generally recommend checking at least once per month as well as any time that you are planning to take your vehicle out of state or drive it more than a few hundred miles for a long road trip.What happens if my tire pressure is too low?
When the pressure in your tires is less than optimal, you get reduced tire life. The tread life of a low-pressure tire wears down unevenly, putting much more stress on the outside edges of the tire, but also more stress in the middle section too.Driving a car or truck that is under-inflated also makes your fuel economy significantly worse, not just for the ride to work or school, but for the ride to the grocery store as well as on your longer trips.
Why is my TPMS dashboard light on?
It comes on whenever one of your vehicle's tires has decreased to 25% of the manufacturer’s recommended optimum pressure. In some vehicles, it only turns on at that level; for others, you get 26 PSI. Regardless, once it illuminates, you should either check your tire’s pressure at a nearby service station or get a reliable tire pressure gauge.Similar threads
