Overview
Tire replacement Tire rotation
Tire age
The date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 2501 indicates that the tire was
manufactured in week 25 of 2001.
BMW recommends the replacement
of all tires when the tires are no more
than 6 years old, even if a tire usage of
10 years is possible.
Spare tires over 6 years old should be
used only in case of emergency. A tire
of this age should be replaced by a new
tire immediately, and should not be
fitted together with new tires.
Between the axles
Tread wear at the front and rear axle is
different and will vary according to indi-
vidual driving conditions. In the interest
of safety and optimal vehicle response,
we advise against rotating tires from
front to rear and vice versa.
If rotating the tires between the axles is
under consideration for economic
reasons, the costs for remounting the
wheels must be calculated against any
savings which might result from the
anticipated extension in tire life. Rota-
tion should always be carried out at
short intervals, with a maximum of
3,000 miles (5,000 km). Consult your
BMW center for more information.
Should you decide to rotate the tires,
it is essential to comply with the
following:
Rotate wheels on the same side of the
vehicle only, otherwise braking effi-
ciency and road grip could be adversely
affected.
Following rotation, correct the tire infla-
tion pressure.
If tires with different sizes are
mounted on the front and rear
axles (refer to the information beginning
on page
116 ), the wheels may not be
rotated from one axle to the other.
