Understanding Tire Pressure and Load Limits
Tire inflation pressure is the level of the 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. (This number is also expressed in kilopascals (kPa)
which is a metric measuring system used internationally).
Vehicle manufacturers determine this number based on the
vehicles' design load limit which 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'. Tire pressure should
always be measured when the tire is 'cold' to get an accurate
measurement. A cold tire is one that hasn't been driven
on for at least 3 (three) hours. As you drive, your tires get
warmer causing the air pressure within the tire to increase.
Therefore, you can not get an accurate measurement of tire
pressure unless the tire is cold.
Checking Tire Pressure
Because tires are designed to be used on more than one type
of vehicle, tire manufacturers list the 'maximum permissible
inflation pressure' on the sidewall. The number is the greatest
amount of air pressure that should ever be put in the tire
under normal driving conditions.
It is important to check your vehicle's tire pressure at least
once a month for the following reasons:
• Most tires naturally lose air pressure over time.
• Tires can lose air suddenly if you drive over a pothole or
strike the curb when parking.
• With radial tires it is usually not possible to determine
under inflation by visual inspection. For your convenience,
purchase a tire pressure gauge to keep in your vehicle.
Tire Safety Tips
Preventing Tire Damage
• Slow down if you have to go over a pothole or other object
in the road.
• Do not run over foreign objects in the roadway, and try not
to strike the curb when parking.

Identification and Safety

Tire Safety Checklist
• Check tire pressure regularly (at least once a month),
including the spare.
• Inspect tires for uneven wear patterns on the tread, cracks,
foreign objects, or other signs of wear or trauma.
• Remove bits of glass and any other foreign objects wedged
in the tread.
• Make sure your tire valves have valve caps.
• Check tire pressure before going on a long trip.
• Do not overload your vehicle. Check the tire information
placard for the maximum recommended load for the
vehicle.
• If you are towing a trailer, remember that some of the
weight of the loaded trailer is transferred to the towing
vehicle.

MAINTENANCE TIP:
When a trailer is being stored for a prolonged
period of time, follow the tips listed below to
help prolong the life of your tires.
• Take the weight off the tires by putting the
trailer on blocks.
• Reduce the air pressure in each tire.
• Protect your tires from the elements by
keeping them covered.
When taking the trailer out of storage, inspect
the tires thoroughly and be sure there are no
cracks in the grooves and no wire showing.
Cracks in the sidewall could indicate interior
damage or separations in the tire.
