Best Gas Mileage - How to Keep Your Tires Optimized to Save Gas and Money

To maintain the proper air pressure in your tires takes very little effort. By doing that simple chore, you can save 4% on your annual gas costs. It is estimated that a 4% savings equates to between $100 and $200 per year. Just follow the advice listed here and start saving.

The manufacturer recommended air pressure for the tires on your car can vary greatly from model to model. It can range anywhere from 20 pounds to 50 pounds per square inch. So how do you find the correct pressure for your tires?

The information that tells you the proper tire pressure for your car is listed on a information label. This label is located in a few standard places on your car. The label can be found on the interior of the glove compartment, trunk, or gas tank door or on the side of one of the car doors or on the post inside one of the car doors. If you cannot easily find the label, the owner's manual should include the correct information or tell you where the pressure label is located.

Many drivers have the mistaken idea that the numbers on the tire sidewall indicate the correct pressure. This couldn't be farther from the truth. The information on air pressure listed on the tire is the maximum tire pressure that can safely be used in that grade tire. It also indicates the highest pressure that should be used in order to load the maximum weight in the vehicle.

When you find the information listing the correct tire pressure, you need to physically measure air pressure in all four tires to guarantee they are inflated properly. There are a few steps involved in doing this correctly.

How to measure and correct tire pressure:

Step 1:

Make sure you have a tire pressure gauge. There are many kinds. You do not need an expensive one. A gauge with a dial is easier to read than the pop up kind.

Step 2:

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.

Step 3:

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.

Step 4:

Press the pressure gauge onto the valve after removing the valve cap. Be sure the gauge is lined up with the valve properly and press hard so that the pressure gauge seals tightly on the valve. If you hear the whoosh of air escaping disengage the pressure meter from the valve and reseat it.You should not hear any air movement if you have the gauge properly seated. When it is seated correctly you can take the reading on the gauge.

Step 5:

If you find the pressure is low, add air to the tire until you get to the correct air pressure. If you find the tire is over inflated or you put too much air in the tire, you can lower the pressure by pushing on the metal stem at the center of the valve which will allow air to escape from the tire. Measure the air pressure again to make sure you have the correct level and adjust the air in or out again if needed. Repeat measuring and adding or purging air until the desired pressure is reached.

Step 6:

Follow this same procedure for the other three 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.

Follow this advice and you will have more money in your pocket every time you fill up. At the end of the year you will have saved $100 to $200 dollars. It's that easy!
