DRIVING & SAFETY — 2
Understanding the Ination Table:
The tire size is on the left margin of the table.
Determine the Single or Dual ination reading,
denoted with a D or S on the Table. Single is for
the front axle. Dual is for the drive axle. On the
following chart, nd the corresponding psi at the
top columns to see the corresponding maximum
weight capacity for that psi.
Rated load capacities are listed for individual
tires in a Dual or Single position.
NOTE:
Every load range has a maximum rating
as well as a minimum rating. DO NOT
exceed those ratings.
WARNING:
DO NOT exceed tire manufacturer’s
maximum speed rating.
Inspecting & Pressure
Weigh all tire positions seperately and use
the tire charts to determine correct tire ination
pressures. All pressures are rated at a cold psi.
Cold psi is dened as early in the morning
before the day’s ambient temperature, sun’s
radiant heat or the heat generated while driving
have caused the tire pressure to temporarily
increase. Check tire ination 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 ination 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 ination 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-ination can cause:
Hard ride.
Tire bruising or carcass damage.
Rapid tread wear in the center of the tire.
Under-ination 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.
