•
Wheel alignment should be done according to the above shown specification at
an unladen condition maintaining the tyre pressure in all tyres as per the tyre
pressure specification chart
•
Wheel alignment is recommended every 10,000 kms, however it can be done
whenever there is an abnormality observed on steering feel or uneven tyre wear
12.4.4 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.
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 being stranded, check the spare
tyre air pressure frequently.
12.4.5 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.
At least once a month or before long trips, inspect each tyre and check the tyre
pressure with a tyre gauge (including spare tyre). Inflate all tyres to the
recommended inflation pressure.
Under-inflation is the most common cause of tyre failures and may result in
severe tyre cracking, tread separation or “blowout”, with unexpected loss of
vehicle control and increased risk of injury. Under-inflation increases sidewall
flexing and rolling resistance, resulting in heat buildup and internal damage to
the tyre. It also may result in unnecessary tyre stress, irregular wear, loss of
vehicle control and accidents.
Always inflate your tyres to the recommended pressure even if it is less than the
maximum inflation pressure information found on the tyre. The recommended tyre
inflation pressure is found on the tyre Label which is located on the front passenger
side inner B-pillar. Failure to follow the tyre pressure recommendations can cause
uneven tread wear patterns and adversely affect the way your vehicle handles.
To check the pressure in your tyre (s);
1.
Make sure the tyres are cool, meaning they are not hot from driving. If you are
checking tyre pressure when the tyre is hot, (i.e. driven more than a km, never
‘bleed’ or reduce air pressure. The tyres are hot from driving and it is normal
for pressures to increase above recommended cold pressures. A hot tyre at
or below recommended cold inflation pressure could be significantly under-
inflated
