Proper tire inflation, toe-in adjustment, loads, and road speeds are
important factors governing tire mileage, steering ease and
maneuverability.
Tire Loading
WARNING: Loading tires beyond their rated capacity decreases
tire life requiring more frequent replacement of tires. Overloading
creates an unsafe condition that may result in sudden air loss from a
tire failure resulting in an accident that could cause property damage,
personal injury or death.
Note: Your GAW/GVW rating is correct at the time of your vehicle
production, and reflects the exact rating of the tires specified. When
replacing tires, make sure that the replacement tire load rating (listed in
pounds and kilograms on the tire sidewall) is the same or higher than
the tire that you are replacing. Failure to do so adversely affects
maximum load carrying capacity. Tires with the same size specification
do not always have the same load specification.
Note: The tire installed as original equipment may not be the same as
the tire specified on the DOT label, but has enough load capacity to
carry the GAW/GVW specified.
Note: Tires with the same size specification do not always have the same
load specification.
Matching Tires
Dual Tires: Dual tires should be matched using tires of equivalent size.
Do not mount tires that differ more than one-quarter inch (6
millimeters) in diameter or three-quarters inch (19 millimeters) in
circumference on the same dual wheel assembly.
Mixing: Never mix bias and radial tires on this vehicle. Never mix
different tire sizes or constructions on the same axle.
Rotation:
Rotation is always advisable:
• If there is irregular wear on the front (steering) axle tires, move to
rear position.
• In a dual assembly, reverse the position of the tires if one tire wears
much faster than its mate does.
• On the drive axle, if heel and toe wear or alternate lug wear occurs,
rotating the tires from one end of the axle to the other end of the
axle may help even out this wear.
