Notes on inflation pressure

108n
Information for your safety
The factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle.
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 26.
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 –
including the spare tire – regularly
(refer to page 26), 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.<
Check the inflation pressure of
the spare tire
For checking tire pressures, there is a
valve extension (arrow) on the storage
tray of the spare wheel which is acces-
sible from outside.

Tire condition

Tire tread – Tire damage
Inspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread pattern depth.
The tread depth should be at least
0.12 in (3 mm), although the legally
permissible minimum tread pattern
depth is 0.063 in (1.6 mm). Wear indica-
tors 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 aquaplaning 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.
