Tires - General
Information
Tire Pressure
Proper tire inflation pressure is
essential for safety and best
performance of your vehicle. The tire
pressure monitoring system “TPMS”
setup on the vehicle (see “Tire
Pressure Monitoring System” in this
section) may alert the driver about
insufficient tire pressure even though
the driver is responsible for checking
regularly the tire pressure.
Radial tires fitted on the vehicle may
look properly inflated even when they
actually are under inflated. Do not
make a visual judgment when
determining proper inflation.
Three primary driving aspects are
affected by improper tire pressure:
Safety
WARNING!
• Improperly inflated tires are
dangerous and can cause collisions.
• Under-inflation increases tire flexing
and can result in tire overheating
and failure.
• Over-inflation reduces a tire's ability
to cushion shock. Objects on the
road and chuckholes can cause
damage that result in tire failure.
• Over-inflated or under-inflated tires
can affect vehicle handling and can
fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause
steering problems. You could lose
control of your vehicle.
• Unequal tire pressures from one side
of the vehicle to the other can cause
the vehicle to drift to the right or
left.
• Always drive with each tire inflated
to the recommended cold tire
inflation pressure.
Economy
Improper inflation pressures may
cause uneven wear patterns to
develop across the tire tread. These
abnormal wear patterns will reduce
tread life resulting in a need for
earlier tire replacement. Under-
inflation also increases tire rolling
resistance resulting in higher fuel
consumption.
Ride comfort and vehicle stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Pressure Checkup
The proper cold tire inflation pressure
is indicated on the table “Tire Inflation
Pressure” in section 8.
Inflation pressure specified on the
label always refers to “cold tire
inflation pressure”. Cold tire inflation
pressure is defined as the tire pressure
after the vehicle has not been driven
for at least three hours, or driven less
than 1.6 km (1 mi) after a three hour
period.
Check tire pressures more often in
case of significant outside
temperature changes, as tire pressure
varies according to temperature
changes.
The pressure should be checked and if
necessary adjusted; tire wear and
overall conditions should also be
checked monthly. Tire pressures
change by approximately 0.07 bar per
7°C of air temperature change. Keep
this in mind when checking tire
pressure inside a garage, especially in
winter.
Example: If garage temperature =
20°C and the outside temperature =
0°C then the cold tire inflation
pressure should be increased by 0.21
