Tire Replacement; Interaxle Tire Changes - BMW 318i Owner's Manual

Tire replacement

112
To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer.
a
Do not use retreaded tires, as oth-
erwise driving safety may be impaired.
This is due to the possible variations in
casing structures and, in some cases, to
their extreme age, which can lead to a
decrease in their durability.c

Interaxle tire changes

Tread wear patterns differ at the front
and rear wheels according to the indi-
vidual operating conditions. In the inter-
est of safety and optimal vehicle
response, we advise against rotating
tires from front to rear and vice versa.
When considering the potential eco-
nomic benefits of interaxle tire rotation,
you must decide whether the expense
of having the tires rotated is likely to be
amortized during the anticipated exten-
sion in tire life. We recommend that you
discuss the matter with your BMW
Retailer.
Should you decide in favor of rotating
the tires, it is essential to observe the
following:
Leave the tires on the same side of the
vehicle (include spare in rotation pat-
tern as desired).
Braking response and traction may be
adversely affected.
Rotation should always be carried out
at short intervals, max. 3000 miles
(approx. 5000 km).
Following rotation always correct the
tire inflation pressure.
Always replace tires after 10 years,
regardless of use or tread wear.
Spare tires over 6 years old should be
used only in case of emergency. Such a
tire should be replaced by a new tire
immediately, and should not be fitted
together with new tires.
The date on which the tire was manu-
factured is indicated by the code on
the sidewall: DOT ... 327 indicates that
the tire was manufactured in Week 32
of 1997.
