Tires in Cold Pressure

Most people don't understand cold pressure doesn't necessarily mean the weather must be cold. It means your tires should be cold when they are checked before you drive.  When you drive, your tires heat up significantly when you drive and the increased temperature causes the pressure to increase.  It is a law of nature that if air is confined to a small area of space such as a tire and the temperature increases, the pressure will also rise.  If the temperature decreases, so will the pressure.  Knowing this, we understand you cannot accurately check the tire pressure of your tires once you have driven a few miles. 

Because tires tend to lose small amounts of air over a period of time, the pressure should be checked once every month.  If your tires only lose a pound or two between checks, this is normal.  Air can sometimes escape through the tiny pores in the rubber much in the same way that a rubber balloon loses air after a few days.  An older tire may be more susceptible  to bigger leaks because the rubber gets dry and can even develop small cracks.  If you check your tires two or three months in a row and you haven't lost any air, you wont need to check the pressure each month. 

When you add air to your tire, make sure you do not over fill it.  Many gas stations have compressed air or your can go to a Downing repair shop or tire shop to have your tires pressure checked and filled for you.  A week after you fill you tires, you will want to check the pressure again to make sure you didn't over fill or lose pressure.  Most tire gauges have a small nipple that is used to push in the valve to let excess air escape if you get too much pressure. If you purchased new tires from a tire dealer, they should be happy to add air for you at no charge. This will help assure them that you will get the most from your tires and purchased from them.
