Tyres - tread wear indicators
A tread wear indicator shows the status of the
tyre's tread.
Tread wear indicators.
Tread wear indicators are narrow treadless
bands across the width of the tread. On the
side of the tyre are the letters TWI (Tread
Wear Indicator). When the tyre's tread depth
is down to 1.6 mm, the tread depth will be
level in height with the tread wear indicators.
Change to new tyres as soon as possible.
Remember that tyres with little tread depth
provide very poor grip in rain and snow.

Tyres - air pressure
Tyres can have different air pressures which
are measured in bar.
Check the air pressure in the tyres
The tyre pressures must be checked every
month.

NOTE
•
Check the tyre pressure when the
tyres are cold. "Cold tyres" means that
the tyres are at the same temperature
as the outdoor temperature. The tyres
will heat up and the tyre pressures will
increase after driving for a few kilome-
tres.
•
Tyre pressures which are too low will
increase fuel consumption, reduce tyre
service life and impair the car's han-
dling. Driving with tyre pressures
which are too low may lead to the
tyres overheating and sustaining dam-
age. Tyre pressures affect ride com-
fort, road noise and steering.
•
Tyre pressure decreases over time,
this is a natural phenomenon. Tyre
pressure also varies depending on
ambient temperature.
