A.3. Finding Your Vehicle’s Recommended Tire Pressure and Load Limits
Tire information placards and vehicle certification labels contain information on tires and
load limits. These labels indicate the vehicle manufacturer’s information including:
· Recommended tire size
· Recommended tire inflation pressure
· Vehicle capacity weight (VCW–the maximum occupant and cargo weight a vehicle is
designed to carry)
· Front and rear gross axle weight ratings (GAWR– the maximum weight the axle
systems are designed to carry).
Both placards and certification labels are permanently attached to the trailer near the left
front.
A.4. Understanding Tire Pressure and Load Limits
Tire inflation pressure is the level of air in the tire that provides it with load-carrying
capacity and affects the overall performance of the vehicle. The tire inflation pressure is
a number that indicates the amount of air pressure– 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 tires are designed to be used on more than one type of vehicle, tire manufac-
turers 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.
A.5. 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.
