The most neglected part of any vehicle seems to be the tires. Below is a compilation of great information on why you need a good tire pressure gauge and how to use it!  

How often do you check your tire pressure? Don’t wait until it’s too late! Check your tire pressure regularly. Proper tire inflation is important for several reasons including safety and fuel efficiency.

Tires with decreased pressure wear unevenly because more of the tire comes in contact with the road. If a tire is under-inflated by as little as 6 PSI the life of the tire can be decreased by as much as 25%. This increased contact also causes more friction with the road which leads to increased fuel consumption. Source…

Checking Your Tire Pressure

Here’s how to check the pressure in your tires with the least amount of muss and fuss.

  1. Buy a digital tire gauge and keep it in the car. (This will only set you back about $10.) Consider buying a small notebook that you can use to record your tire pressure and, later, your increased fuel economy.
  2. Find the tire pressure level required for your car. This information is usually on a yellow sticker in the doorjamb on the driver side (and it is also contained in the owner’s manual). It might call for different pressure levels for the back tires and the front tires.
  3. Check the pressure when the tires are cold. Tires heat up as they drive. They take about a half hour to cool down. Or you can just check the tires first thing in the morning.
  4. Unscrew the valve cap and set it to the side or in a pocket where you won’t lose it.
  5. Press the tire gauge onto the valve stem. There might be a slight hiss as you press down on the valve stem and again as you release it. You only need to do this for a second or two, long enough to get an accurate reading.
  6. Read the tire pressure on the digital gauge. You might consider writing down the pressure of the tires as you go around the car. You can refer to this when you fill up the tires.


Now you can compare the tire pressure readings you got with the specified amount called for by the manufacturer (on the doorjamb or in the manual). If the level of pressure in your tires is below the specified amount, you need to fill the tires with air.

For example, the sticker on the doorjamb may say that the recommended level is 32 psi (pounds per square inch). When you check your tire you find it is 29 psi. You need to bring your tire pressure up to spec. It’s estimated that for every 3 psi below spec, you burn 1 percent more fuel (and add 10 percent more tire wear). It’s not uncommon to be 10 psi below spec, which would waste 3 percent more fuel and increase tire wear by 45 percent.


Some of the best found information on the internet and this shows the importance of buying a good tire pressure gauge.  Many people used to avoid the task of checking tires as it was a cumbersome and awkward task.  Not any more with the latest generation of gauges.
