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 depth.
Tread depth should not be allowed to go
below
1/8 in / 3 mm, even though in
Europe, for example, the legally specified
minimum tread depth is only
1/16 in /
1.6 mm.
Tread wear indicators in the tread-groove
base – see arrow – are distributed around
the wheel circumference and are labeled
on the tire sidewall as TWI – Tread Wear
Indicator. At a tread depth of
1/16 in /
1.6 mm, the indicators signal that the
legally permissible wear limit has been
reached.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading can cause over-
heating and damage inside the tires.
The ultimate result can assume the form of
a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate tire
failure or some other vehicle malfunction.
This type of problem can be caused by
contact with curbs, etc. This is also true for
irregularities in the vehicle's handling char-
acteristics, such as a pronounced ten-
dency to pull to the left or right. Should this
occur, respond by immediately reducing
your speed. Proceed carefully to the near-
est BMW center or professional tire center,
or have the vehicle towed there to have it
and its wheels or tires inspected.
Tire damage – up to and including sudden and complete air loss – can pose an
extreme hazard for both vehicle occupants
and other road users.<
Tire replacement
To maintain good handling and vehicle
response, use tires of a single tread config-
uration from a single manufacturer.
BMW advises against using retreaded
tires as this could negatively affect
driving safety. This is due to possible varia-
tions in casing structures and, in some
cases, to their extreme age, factors which
can lead to a decrease in their durability.<
Tire age
The date on which the tire was manufac-
tured is indicated by the code on the side-
wall:
DOT … 3602 indicates that the tire was
manufactured in week 36 of the year 2002.
BMW recommends the replacement of all
tires every 6 years at the latest, even if a tire
usage of 10 years is possible.
Run Flat tires
When replacing tires, always use
Run Flat tires since a spare wheel is
not provided to replace a flat tire.
Run Flat tires are labeled on the sidewall
with a circular symbol containing the letters
RSC. Refer to page 75.<
DOT quality grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.<
Tread wear
The tread wear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course.
For example, a tire graded 150 would wear

Winter tires
Choosing the right tire
BMW recommends Run Flat winter tires –
M+S – for operation under inclement winter
driving conditions. While all-season tires
with the M+S identification mark do indeed
possess better winter traction than summer
tires that have the H, V, W, Y and ZR speed
ratings, they generally do not provide the
same levels of performance as true winter
tires.
In the interests of sure tracking and safe
steering response, mount winter tires
which are made by the same manufacturer
and which have the same tread configura-
tion on all four wheels.
Your BMW is equipped with Run Flat tires.
Please consult your BMW center if you
wish to replace the tires of your BMW or
change from summer to winter tires, or vice
versa.
When replacing tires or changing from
summer to winter tires – or vice versa –
use only Run Flat tires since a spare tire will
not be available in the event of a flat tire.<
Comply with recommended speed
Never exceed the maximum speed for
which the winter tires are rated.
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and acci-
dents.
Have this work performed by skilled pro-
fessionals only. Any BMW center has the
required technical knowledge and the
proper equipment and will be happy to
assist you.<
Tire condition, tire pressure
Once the tire wears to below 3/16 in /
4 mm, winter tires display a perceptible
decrease in their ability to cope with winter
driving conditions, and should be replaced
in the interest of safety.
Comply with the specified tire inflation
pressures – and be sure to have the wheel
and tire assemblies balanced every time
you change the tires.
Storage
Store tires in a cool, dry place, protecting
them against light whenever possible. Pro-
tect the tires from contact with oil, grease
and fuel.
Snow chains*
Only certain types of snow chains have
been tested by BMW, classified as road-
safe and approved. Consult your BMW
center for more information. BMW recom-
mends using only approved fine-link snow
chains.
Their use is only permitted in pairs on the
winter tires on the rear wheels. Comply
with all manufacturer's safety precautions
when mounting the chains.
You cannot mount snow chains on the fol-
lowing tires:
245/40 R 17
255/35 R 18
Do not exceed a speed of 30 mph /
50 km/h when using snow chains.<
Do not initialize the Flat Tire Monitor
after snow chains have been
mounted.
When driving with snow chains, it may be
useful to deactivate the DSC briefly. Refer
to page 51.<
