2012 Trip
Understanding the Load Inflation Table:
The tire size is listed in the left margin of
the table. Inflation pressure and weight rating
will vary depending if the wheel position has
a single tire indicated by S or a dual wheel
position (drive axle) indicated by a D. Locate
the corresponding psi at the top columns to
obtain the correct inflation pressure for a given
wheel position. All tires on any axle must be
inflated to the heaviest wheel position on that
axle due to weight transfer that occurs when
cornering.
NOTE:
Every load range has a maximum
rating as well as a minimum rating. Do
not exceed those ratings.
NOTE:
If weight of a wheel position is under
the minimum weight rating. the tire(s)
must be inflated to the minimum
weight rating as listed in the table.
WARNING:
Do not exceed the tire manufacturer’s
maximum speed rating.
Inspecting & Pressure
Inflation pressure is rated at a cold psi. Cold
psi is defined as early in the morning before
the day’s ambient temperature, sun’s radiant
heat or the heat generated while driving have
caused the inflation pressure to temporarily
increase. Check tire inflation pressure every
morning before driving. Use a quality truck
tire gauge with an angle airhead to ensure
access to the dual wheel positions of the drive
axle.
Ensure the valve cap is replaced on the stem
after the inflation pressure is checked. Use
valve stem caps with a positive seal to prevent
air escaping from the valve stem. If there are
extension hoses on the valve stem, make sure
they are good quality reinforced stainless steel
braid. Attach hoses securely to the outer wheel.
The valve stem cap guarantees the valve core
will remain free of dirt and foreign material.
Material lodged between the valve core and
internal stem can cause slow leaks resulting in
tire failure.
Optimum tire performance is achieved at
proper inflation pressure for the load carried.
Do not mix tires of different tread patterns,
size or construction on the same axle. The
difference in traction could cause rear end gear
bind and mechanical damage to the drive train.
CAUTION:
Never let air out of a hot tire.
Over-inflation can cause:
Hard ride.
Tire bruising or carcass damage.
Rapid tread wear in the center of the
tire.
Under-inflation can cause:
Tire squeal on turns.
Separations.
Rapid and uneven wear on the edges of
the tread.
Circumferential breaks.
Tire container may bruise or rupture.
Higher risk of road hazard.
Tire cord breakage.
Loss of casing durability.
Excessive tire temperature.
High fuel consumption.
Reduced handling quality.

WARNING:
A slow leak may go unnoticed on one
of the dual tires. This can cause the
good tire to fail by exceeding the load
limit. Tires with damaged sidewalls
can burst upon inflation. A flat or
nearly flat tire can also generate
enough heat from friction to ignite.
Unequal tire pressures on same axle can
cause:
Uneven braking.
Swerve upon acceleration.
Steering lead.
Torque steer.
Reduced handling quality.
WARNING:
For safety purposes, clear the area of
people and pets during tire inflation.
Inflate tires using a remote inflation
device.
