Checking
Tire Pressure
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. |
