measured in pounds per square inch (psi)–a tire requires to be properly
inflated. (You will also find this number on the vehicle information placard
expressed in kilopascals (kpa), which is the metric measure used
internationally.)
Manufacturers of passenger vehicles and light trucks determine this number
based on the vehicle's design load limit, that is, the greatest amount of
weight a vehicle can safely carry and the vehicle's tire size. The proper tire
pressure for your vehicle is referred to as the "recommended cold inflation
pressure." (As you will read below, it is difficult to obtain the recommended
tire pressure if your tires are not cold.) Because by design tires can be used
on more than one type of vehicle, tire manufacturers list the "maximum
permissible inflation pressure" on the tire sidewall. This number is the
greatest amount of air pressure that should ever be put in the tire under
normal driving conditions.
1.5.3. CHECKING TIRE PRESSURE
It is important to check your vehicle's tire pressure at least once a month for
the following reasons:
• Most tires may naturally lose air over time.
• 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.
