Car care
Date code
Tires should be regarded as perishable
goods. As the tires age, the rubber becomes
progressively harder, and the roadholding
ability of the tires diminishes. This is partic-
ularly true on winter tires.
Tires now have a date-code marking for the
year of manufacture. The first two digits
denote the week number and the last two
digits the year. The ”<” symbol points to the
year.
Accordingly, a date code of 0200 signifies
that the tire was manufactured in week 02,
2000.
Wear indicators
The tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only
2/32" (1.6
mm) of tread remains. As soon as
the indicators become visible, new tires
should be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter tires.
Compact spare wheel
The compact spare is light and easy to
handle when changing the wheel. Its use is
only permitted when a standard wheel has
sustained a puncture. The maximum life of
the wheel is only 2000 miles (3,500 km).
Do not exceed 50
mph (80
km/h) with the
compact spare fitted.
The compact spare should be inflated to
60
psi (420
kPa). Carry the punctured tire in
the spare-wheel well under the trunk floor.
Have the standard wheel repaired and refit-
ted as soon as possible
Driving considerations with compact spare
wheel/tire fitted, see page 190.
The spare wheel, the tools and the jack with
its crank are carried under a panel in the
trunk.
