Ride Comfort and Vehicle Stability
Proper tyre inflation contributes to a comfortable and safe ride.
Overinflating produces a jarring and uncomfortable ride. Both
underinflation and over inflation affect the stability of the vehicle;
induce
the
perception
feeling
of
hard
steering
or
over
responsiveness in the steering. Unequal tyre pressures can cause
erratic and unpredictable steering response or may cause the
vehicle to drift left or right and uncomfortable ride.
Improper inflation pressures can cause uneven wear patterns to
develop across the tyre tread. These abnormal wear patterns will
reduce tread life resulting in a need for earlier tyre replacement.
Underinflation also increases tyre rolling resistance and results in
higher fuel consumption.
The proper cold tyre inflation pressure is listed in the tyre Label
(Vehicle Placard), located on the front passenger side inner B-
pillar.
12.4.1 Inspection and Adjustment Procedure
The tyre pressure should be checked and adjusted, as well as
inspected for signs of tyre wear or visible damage, at least once a
month. Use a good quality pressure gauge to check tyre pressure.
Do not make a visual judgement when determining proper inflation.
Radial tyres may look properly inflated even when they are
underinflated. At the same time, each tyre should be inspected for
signs of tyre wear or visible damage.
Inflation pressures specified on the placard are always cold tyre
inflation pressures.It is better to check the tyre pressure in morning
when the vehicle is not driven for more than 1 to 2 Km. Cold tyre
inflation pressure is defined as the tyre pressure after the vehicle
has not been driven for at least three hours, or driven less than 1
km after a three-hour period. Check tyre pressures more often if
subject to a wide range of outdoor temperatures, as tyre pressures
vary with temperature changes. tyre pressures change by
approximately 1 psi (7 kPa) per 7° C of air temperature change.
Keep this in mind when checking tyre pressure inside a garage,
especially in the winter.
When it was new, the spare tyre in your vehicle was fully inflated.
However, a spare tyre can lose pressure over time. In order to
avoid getting stranded, check the spare tyre air pressure
frequently.
12.4.2 Inflating Your tyres
Safe operation of your vehicle requires that your tyres are properly
inflated. Remember that a tyre can lose up to half of its air
pressure without appearing flat.
