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 correct tire pressure for your vehicle is listed on the information placard. This placard is normally located on the edge of one of the doors, the inside post of one of vehicle's doors or inside the glove compartment, trunk, or fuel door. Your owner's manual should include the correct tire pressure or direct you to the placard's location on your vehicle. 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: 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: Determine the proper pressure for your tires by checking the pressure label or the owner's manual. Now you are ready to measure. Step 3: Only measure pressure when the tires are cold. Tires are cold if they have not been driven for more than 1 mile or have been at rest at least 3 hours. Step 4: Complete tire inflation pressure check: Remove the cap from the valve on one tire, press the pressure gauge onto the valve and take a pressure reading. Make sure you press the pressure gauge completely onto the valve. You should not hear any air escaping from the tire as you are taking the reading. If air is escaping, remove the gauge from the valve and try reseating it again. 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!
