Temperature
The temperature grades are A, the highest,
B and C, representing the tire's resistance
to the generation of heat and its ability to
dissipate heat when tested under con-
trolled conditions on a specified indoor lab-
oratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
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 repre-
sent 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, underinflation, or excessive load-
ing, either separately or in combination,
can cause heat buildup and possible tire
failure.<
RSC: run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire, refer to page192.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
Tire condition
Inspect your tires frequently for treadwear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.
Tire tread
The tread depth should not drop below
εin/3 mm, although, for example, Euro-
pean legislation only specifies a minimum
tread depth of κ/ΦΚin/1.6 mm. At tread
depths below εin/3 mm, there is an
increased risk of high-speed hydroplaning, even when only small amounts of water are
present on the road surface.
As winter tires display a noticeable loss in
their ability to cope with cold-weather driv-
ing conditions once the tread wears to
below κ/Κin/4 mm, to ensure continued
safety you should always have such tires
replaced.
Wear indicators at the tread-groove base,
refer to arrow, are distributed over the tire's
circumference and are marked on the side
of the tire with TWI – Tread Wear Indicator.
These indicators signal at a tread depth of
κ/ΦΚin/1.6 mm that the legally permitted
wear limit has been reached.
Wheel/tire damage
Due to low-profile tires, please note
that wheels, tires and suspension
parts are more susceptible to road hazard
and consequential damages.
Unusual vibrations encountered during
normal vehicle operation can indicate tire
failure or some other vehicle defect. This
can, for example, be caused by driving over
curbs. These kinds of problems may also
be signaled by other changes in vehicle
response, such as a strong tendency to pull
to the left or right.
In these cases reduce speed immediately.
Drive carefully to the next BMW center or
tire dealer, or have the vehicle towed to one
of these locations if necessary.
Tire damage, extending to sudden and
complete loss of pressure in extreme
cases, can pose a potentially lethal safety
hazard for the vehicle's occupants and
other road users alike.<

remounted on the vehicle as soon as pos-
sible.
Recommended tire sizes and brands
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. You can find out about
these at specialized dealers or at your
BMW center. Observe any country-specific
regulations, e.g. on making a correspond-
ing entry in the vehicle documents.
The factory-mounted tires have been spe-
cially selected to provide optimized perfor-
mance when installed on your vehicle; if
properly cared for, they will provide a com-
bination of safety and excellent ride com-
fort.
Run-flat tires
If your BMW is equipped with run-flat tires,
refer to Run-flat tires, only use these tires,
as in the event of a breakdown there is no
spare tire available.
Special characteristics of winter
tires
BMW recommends winter tires for use in
cold winter driving conditions. Although so-
called all-season M+S tires provide better
winter traction than summer tires, they
generally fail to provide the same levels of
cold-weather performance as winter tires.
Run-flat tires
When mounting new tires or switching from
summer to winter tires, or vice versa, use
run-flat tires, as in the event of a break-
down there is no spare wheel available.
Your BMW center will be glad to advise
you.
Observing speed ratings
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
professionals only. The technicians at your
BMW center will be glad to assist you with the required professional knowledge and
specialized equipment.<
Storage
Always store wheels and tires in a cool, dry
pl ace w it h as l itt le exp osu r e t o li gh t a s po s-
sible. Always protect tires against all con-
tact with oil, grease and fuels.
Do not exceed the maximum tire inflation
pressure indicated on the side wall of the
tire.
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves
them. Consult your BMW center for more
information. BMW recommends only using
these approved, narrow-link snow chains.
Use on summer or winter tires is only per-
missible in pairs on the rear wheels.
Observe the manufacturer's instructions
when installing snow chains.
Do not exceed a vehicle speed of 30 mph/
50 km/h with the chains mounted.
After mounting snow chains, do not
activate the Flat Tire Monitor.
When you are driving with snow chains, it
can be beneficial to switch off DSC briefly,
refer to page94.<
