You can save 4% on your annual gas costs if you keep your tires at the recommended Pounds per Square Inch (PSI). That could save your family from $100 to $200 dollars annually. To determine and maintain the proper tire pressure requires very little effort. The steps are listed below.
Correct tire pressure varies from vehicle to vehicle and wheel to wheel. In fact, the recommended pressure for personal vehicles ranges from 20 to over 50 psi.
The proper tire inflation amount is usually found on a tire information sticker mounted somewhere on your car. This informational sticker is found in standard places on your car. The informational sticker can be found on the inside of the trunk, gas tank door or glove compartment. Sometimes it can be located on a car visor or on a post inside a car door or on the side of the door itself. The owner’s manual will also list the tire pressure information or possibly indicate where the informational sticker is located.
A common misconception is that the pressure listed on the tire sidewall is the manufacturer’s recommended tire pressure. It is not. It is actually the maximum tire pressure that the tire can safely be inflated to. This is also usually the pressure that is required to carry the maximum load the tire is rated for.
Once you know the correct tire pressure, you need to measure the tire pressure on all tires to ensure they are inflated correctly. The correct way to determine tire pressure:
To measure and maintain proper tire pressure:
First and foremost you need a tire pressure gauge. This may seem obvious but many people think they can tell if a tire is low by sight. I would not recommend that. You don’t need an expensive gauge. One with a dial is easier to use than the kind with the pop up.
Check the tire air pressure informational sticker or the car operating manual to determine the manufacturer suggested pressure for your tires. Once you have that information you can proceed with the actual measurement.
Tire air pressure should only gauged when the tires are cold. A tire that has been at rest at least 3 hours or a tire that has not been driven for more than 1 mile is considered a cold tire.
Remove the top or cap from the valve on the tire and insert the gauge onto the valve. Make sure you press the gauge snugly on the valve. You should not hear air coming from the tire if you have the pressure gauge properly affixed onto the valve. If you hear air escaping pull the gauge off of the valve and reseat it. Once it is seated properly you can note the reading on the gauge.
Add air to achieve recommended air pressure. If you overfill the tire, release air by pushing on the metal stem in the center of the valve, then re-measure the pressure.
Repeat the above procedure for each of the tires.
The standard recommendation that tire experts suggest is to check your tire pressure at least once per month. The tire pressure will change from day to day as air permeates from the tire over time. Heat and driving conditions can accelerate the rate that air pressure is lost. If you are able to check the pressure once each month you can be sure that the tires on your car will remain at the proper pressure all the time.
This is one of the easiest ways to save $100 to $200 dollars of gas costs. Just follow this advice and you will have more money in your pocket.
