2006 BMW M3 CONVERTIBLE winter tires

Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and does
not include acceleration, cornering,
hydroplaning, or peak traction charac-
teristics. highest, B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, under-inflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure. better winter driving properties than
summer tires.
Tire conditionWheel/tire damageInspect your tires frequently for signs of
damage, foreign objects and tread
wear, and check tread depth.
Due to low-profile tires, please
note that wheels, tires and sus-
pension parts are more susceptible to
road hazard and consequential dam-
ages.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect.
This type of problem can be caused by
contact with curbs, etc. This is also true
for irregularities in the vehicle's han-
dling characteristics, such as a pro-
nounced tendency to pull to the left or
right.
Should this occur, respond by immedi-
ately reducing your speed. Proceed
carefully to the nearest BMW center or
professional tire center, or have the
vehicle towed there. Tire damage, up to
and including blowouts, can endanger
the lives of both the vehicle occupants
and other road users.<

Tire treadTread depth should not be allowed to
go below 1/8 in/3 mm, even though
European legislation, for example,
requires a mimimum tread depth of only
1/16 in/1.6 mm. Below 1/8 in/3 mm
tread depth, there is a great risk of
hydroplaning, even at relatively moder-
ate speeds and with only small amounts
of water on the road.
At tread depths below approx.
3/16 in/4 mm, tire performance under
winter driving conditions deteriorates
noticeably. Worn tires should therefore
be replaced for safety considerations.
Tread wear indicators in the tread-
groove base, see arrow, are distributed
around the wheel circumference and
are labeled on the tire sidewall with
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.
New wheels and tires
Have new wheels and tires
mounted only by a BMW center or
specialized tire shop that works
according to BMW requirements with
appropriately trained personnel. Work
that is improperly carried out could
result in consequential damage and
pose safety hazards.<
Ask your BMW center for details con-
cerning the correct wheel and tire com-
bination. Have the wheels balanced
each time a wheel or tire has been
replaced.
The correct wheel and tire combination
also affects different systems such as
ABS or DSC. The function of these sys-
tems is impaired if improper wheel and
tire combinations are used.
BMW advises against using
retreaded tires, as driving safety
could otherwise be impaired. The rea-
son for this are the possibly different
tire casing structures involved, some of
which may be greatly aged, factors
which can lead to a decrease in durabil-
ity.<

The correct wheels and tires
BMW recommends using only
wheels and tires that have been
tested and approved by BMW for the
particular vehicle model, as otherwise
body contact and serious accidents can
result despite the use of the same nom-
inal size, e.g. due to manufacturing tol-
erances. If non-approved wheels and
tires are used, BMW cannot evaluate
their suitability, and therefore cannot be
held liable for driving safety.<
To maintain good handling characteris-
tics, only use a full set of tires of the
same brand and tread configuration.
After a flat tire, have the previous wheel
and tire combination restored as soon
as possible.
Recommended tire sizes and
brandsFor each tire size, certain tire brands
have been tested, classified as road-
safe and approved by BMW. You can
find out about these from a professional
tire center, preferably your BMW cen-
ter. Observe any country-specific regu-
lations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-approved radial belt tires
are matched to your vehicle and pro-
vide optimum safety and driving com-
fort when used properly.Special characteristics of winter
tiresBMW recommends the use of winter
tires for operation under winter road
conditions. While all-season tires with
M+S designation provide better winter
traction than summer tires, they gener-
ally do not achieve the full performance
of winter tires.Observing speed ratings
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW center
will be glad to assist you with the
required professional knowledge and
specialized equipment.<
StorageAlways store tires in a cool, dry place.
Store them away from light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel. Do not
exceed the maximum tire inflation pres-
sures specified on the tire sidewall.

Snow chains*Only certain snow chains have been
tested by BMW and determined and
approved as roadworthy. Consult your
BMW center for more information.
BMW recommends using only these
approved fine-link snow chains. Use
them in pairs on winter tires, but only on
both rear wheels.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph /
50 km/h with snow chains.
After mounting or removing snow
chains, always reinitialize the sequential
M gearbox with Drivelogic, refer to
page 87.
It is not possible to mount snow
chains on tires with 18- and 19-
inch wheels.
Deactivate the Flat Tire Monitor when
using snow chains. Malfunction warn-
ings and undetected losses in pressure
are a possibility when driving with snow
chains.
When driving with snow chains, it may
be useful to deactivate DSC, refer to
page 86.<
