Information for your safety
The factory-approved radial tires are
matched to the car and have been se-
lected to provide optimum safety and
driving comfort on your car.
In a very real sense, both tire life and
your own safety are riding on correct
tire specifications and inflation pres-
sures. Refer to page
29 .
Incorrect inflation pressure is a frequent
cause of tire damage. It also signifi-
cantly influences the roadholding ability
of your BMW.
Check the tire pressures – includ-
ing the spare tire
*
– regularly (at
least every two weeks and before you
begin an extended journey). If this is not
done, incorrect tire pressures may
cause tire damage and accidents.

the spare tire

For checking tire pressures on the
Z3 roadster and Z3 coupe, there is a
valve extension (arrow) on the storage
tray of the spare wheel which is acces-
sible from outside.

Tire tread – Tire damage
Inspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread.
The tread depth should be at least
0.12 in (3 mm), although the legally
permissible minimum tread depth is
0.063 in (1.6 mm). Wear indicators
appear in the tread at 0.063 in (1.6 mm)
to indicate that the legally permissible
wear limit has been reached. There is a
significantly increased risk of aquaplan-
ing at higher speeds when the tread
depth is below 0.12 in (3 mm), even if
there is only a small amount of water on
the road surface.
