MAINTENANCE
TYRES
Tyres
Check for inflation and condition of
your car tyres periodically.
Inflation :
Check the pressure in the tyres when
they are cold.
You should have your own tyre
pressure gauge and use it at all
times. This makes it easier for you to
tell if pressure loss is caused by a
tyre problem and not by variation
between gauges.
Keeping the tyres properly inflated
gives you the best combination of
comfort, handling, tyre life and better
fuel efficiency.
Over inflation of tyres makes the car
ride bumpy and harsh. Tyres are
more prone to uneven wear and
damage from road hazards.

1. Underinflation : Excessive
Side Tread Wear
2. Correct Tyre Pressure :
Uniform Tyre Wear
3. Overinflation : Excessive
Centre Tread Wear
Under inflated tyres reduce your
comfort in car handling and are prone
to failures due to high temperature.
They also cause uneven wear and
more fuel consumption.
CAUTION
Every time you check inflation
pressure, you should also
examine tyres for damage, foreign
objects and wear.

Cuts, splits or cracks in the side
of the tyre. Replace the tyre if
you notice this on the fabric or

NOTICE
Lower air pressure (Front - 26 &
Rear - 28 psi) is recommended
if you prefer riding comfort
