Tires can lose air suddenly if you drive over a pothole or other object or if you strike the curb
when parking
•
With radial tires, it is usually not possible to determine under-inflation by visual inspection
For convenience, purchase a tire pressure gauge to keep in your vehicle. Gauges can be purchased at tire
dealerships, auto supply stores, and other retail outlets.
The recommended tire inflation pressure that vehicle manufacturers provide reflects the proper psi when
a tire is cold. The term cold does not relate to the outside temperature. Rather, a cold tire is one that has
not been driven on for at least three hours. When you drive, your tires get warmer, causing the air pressure
within them to increase. Therefore, to get an accurate tire pressure reading, you must measure tire
pressure when the tires are cold or compensate for the extra pressure in warm tires.
Steps for Maintaining Proper Tire Pressure
•
Step 1: Locate the recommended tire pressure on the vehicle’s tire information placard,
certification label, or in the owner’s manual
•
Step 2: Record the tire pressure of all tires
•
Step 3: If the tire pressure is too high in any of the tires, slowly release air by gently pressing on
the tire valve stem with the edge of your tire gauge until you get to the correct pressure
•
Step 4: If the tire pressure is too low, note the difference between the measured tire pressure and
correct tire pressure. These “missing” pounds of pressure are what you will need to add
•
Step 5: At a service station, add the missing pounds of air pressure to each tire that is under-
inflated
•
Step 6: Check all the tires to make sure they have the same air pressure (except in cases in which
the front and rear tires are supposed to have different amounts of pressure)
If you have been driving your vehicle and think that a tire is under-inflated, fill it to the recommended
cold inflation pressure indicated on your vehicle’s tire information placard of certification label. While
your tire may still be slightly under-inflated due to the extra pounds of pressure in the warm tire, it is safer
to drive with air pressure that is slightly lower than the vehicle manufacturer’s recommended cold inflation
pressure than to drive with a significantly under-inflated tire. Since this is a temporary fix, don’t forge tot
recheck and adjust the tire’s pressure when you can obtain a cold reading.
Tire Size
To maintain tire safety, purchase new tires that are the same size as the vehicle’s original tires or another
size recommended by the manufacturer. Look at the tire information placard, the owner’s manual, or the
