This portion of the User’s Manual contains tire
safety information as required by 49 CFR 575.6.
Section 2.1 contains “Trailer Tire Information”
Section 2.2 contains “Steps for Determining Correct
Load Limit - Trailer”.
Section 2.3 contains “Steps for Determining Correct
Load Limit – Tow Vehicle”.
Section 2.4 contains a Glossary of Tire
Terminology, including “cold inflation pressure”,
“maximum inflation pressure”, “recommended

NFORMATION
Trailer tires may be worn out even though they still
have plenty of tread left. This is because trailer
tires have to carry a lot of weight all the time, even
when not in use. It is actually better for the tire to
be rolling down the road than to be idle. During
use, the tire releases lubricants that are beneficial to
tire life. Using the trailer tires often also helps
prevent flat spots from developing.
The main cause of tire failure is improper inflation.
Check the cold tire inflation pressures at least once
a week for proper inflation levels. “Cold” means
that the tires are at the same temperature as the
surrounding air, such as when the vehicle has been
parked overnight. Wheel and tire manufacturers
recommend adjusting the air pressure to the trailer
manufacturer’s recommended cold inflation
pressure, in pounds per square inch (PSI) stated on
the vehicle’s Federal Certification Label or Tire
Placard when the trailer is loaded to its gross
vehicle weight rating (GVWR). If the tires are
inflated to less than the recommended inflation
level or the GVWR of the trailer is exceeded, the
load carrying capacity of the tire could be
dramatically affected. If the tires are inflated more
than the recommended inflation level, handling
characteristics of the tow vehicle/trailer
combination could be affected. Refer to the
owner’s manual or talk to your dealer or vehicle
manufacturer if you have any questions regarding
proper inflation practices.
Tires can lose air over a period of time. In fact, tires
can lose 1 to 3 PSI per month. This is because
molecules of air, under pressure, weave their way
from the inside of the tire, through the rubber, to the
outside. A drop in tire pressure could cause the tire
to become overloaded, leading to excessive heat
build up. If a trailer tire is under-inflated, even for
a short period of time, the tire could suffer internal
damage.
