Tire age
Tire ageThe tire's date of manufacture is included
in the tire coding:
DOT...3506 means that the tire was manu-
factured in the 35th week of the year 2006.
The manufacturer of your MINI recom-
mends replacing all tires after 6 years at
the latest, even if a tire service life of
10 years is possible.Uniform Tire Quality GradingQuality grades can be found where applica-
ble on the tire sidewall between tread
shoulder and maximum section width.
For example:
Treadwear 200 Traction AA
Temperature A
DOT quality gradesTread 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. 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
one and one-half, 1γ, times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly
from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.

OVERVIEW REPAIRSOPERATIONCONTROLS DATA INDEX
TIRE CODING TIRE CONDITION Traction The traction grades, from highest to low-
est, are AA, A, B, and C.
Those grades represent the tire‘s ability to
stop on wet pavement as measured under
controlled conditions on specified govern-
ment test surfaces of asphalt and concrete.
A tire marked C may have poor traction per-
formance.
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not include
acceleration, cornering, hydroplaning, or
peak traction characteristics. 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 represent
higher levels of performance on the labora-
tory 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 loading,
either separately or in combination, can
cause heat buildup and possible tire fail-
ure. lar symbol containing the letters RSC on
the side of the tire, refer to page111.M+SWinter and all-season tires.
These have better winter performance
properties than summer tires.
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.Tire treadTread 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.
Below 1/8 in/3 mm tread depth, there is a
very high danger of hydroplaning at higher
speeds, even with only small amounts of
water on the road.
At tread depths below approx. 1/6 in/
4 mm, the ability of winter tires to cope
with winter driving conditions decreases
perceptibly. For safety reasons, new tires
should be mounted.

110
TIRE CONDITIONWear indicators in the tread-groove base
are spread around the circumference of the
tire and are marked on the sidewall of the
tire with TWI, Tread Wear Indicator. When
tire tread is worn down to the level of the
wear indicators, the remaining tread depth
is 1/16 in/1.6 mm.
Wheel/tire damage
Due to low-profile tires, please note
that wheels, tires and suspension
parts are more susceptible to road hazards
and consequential damage.
Unusual vibrations during driving may indi-
cate tire damage or other damage to the
vehicle. This may be caused, for example,
by driving over a curb. This is also true for
abnormalities in the vehicle's handling
characteristics, such as a pronounced ten-
dency to pull to the left or right.
In such situations, reduce your speed
immediately. Drive carefully to the nearest
MINI Dealer or tire dealer, or have the vehi-
cle towed there, if necessary.
Tire damage can endanger the lives of both
the vehicle occupants and other road
users.<

RUN-FLAT TIRES
*
You will recognize Run-Flat Tires by a circu-
lar symbol containing the letters RSC on
the side of the tire.
Run-Flat Tires consist of conditionally self-
supporting tires and special rims. The tire
reinforcement ensures that driving
remains possible to a restricted degree in
the event of a pressure drop or even a flat
tire.
For information on continuing to drive with
a flat tire, refer to Flat tire warning,
page75.
Tire change set
In case of a flat tire, the tire change
set is not needed, since your vehicle
has Run-Flat Tires.
When changing a tire, always observe the
safety measures and the procedure for
changing tires starting on page133.<
Your vehicle is additionally equipped with a
tire change set.
In the MINI COOPER and MINI COOPER Con-
vertible this is located in the luggage com-
partment under the floor mat.
In the MINI COOPER S and MINI COOPER S
Convertible, the tire change set is located in
a separate bag which is attached to the
lashing eyelets on the luggage compart-
ment floor by means of tie-down straps.
Have new wheels and tires mounted
only by your MINI Dealer or a special-
ized tire shop that has specially trained per-
sonnel working in accordance with the
specifications of the MINI manufacturer.
Work that is improperly carried out could
result in consequential damage and pose
safety hazards.<
Retreaded tires
The manufacturer of your MINI rec-
ommends that you avoid using
retreaded tires, as this could impair driving
safety. This is due to possible variations in
casing structures and, in some cases, to
their extreme age, factors which can lead
to limited durability.<

112
NEW WHEELS AND TIRESThe correct wheels and tires
The manufacturer of your MINI rec-
ommends mounting only wheels and
tires that it has specifically approved for
use on your particular model. Although
other wheels and tires may theoretically
have the same dimensions, variations in
factors such as manufacturing tolerances
can result in contact between tire and
bodywork, ultimately leading to serious
accidents. The manufacturer of your MINI
cannot evaluate non-approved wheels and
tires to determine if they are suited for use,
and therefore cannot ensure the operating
safety of the vehicle if they are mounted.<
Your MINI Dealer will be glad to inform you
about the correct wheel and tire combina-
tion for your vehicle.
The correct wheel and tire combination is
also important for various systems that
would otherwise be impaired, e.g. ABS or
DSC.
To maintain good handling and vehicle
response, use only tires of a single brand
and tread configuration. In the event of tire
damage, remount the previous wheel and
tire combination as soon as possible.
Run-Flat TiresFor your own safety, use Run-Flat Tires
when mounting new tires or replacing
summer tires with winter tires or vice
versa. Keep in mind that no spare wheel is
available in the event of a flat. Your MINI
Dealer will be glad to advise you.
For safety reasons, the manufacturer
of your MINI recommends having
Run-Flat Tires replaced, not repaired, if they
are damaged.<
Tire designationFor each tire size, the manufacturer of your
MINI recommends certain tire brands. You
can recognize these by the clearly visible
designation on the tire's sidewall.
When used properly these tires meet the
highest standards regarding safety and
handling characteristics.

Special characteristics of winter tires
The manufacturer of your MINI recom-
mends winter tires for driving in adverse
winter road conditions. While all-season
tires with the M+S designation provide bet-
ter winter traction than summer tires, they
generally do not achieve the full perfor-
mance of winter tires.
Observe speed ratings:
Never exceed the maximum speed
for which the winter tires are rated. them against light whenever possible. Pro-
tect the tires against contact with oil,
grease and fuel. Do not exceed the tire
inflation pressure specified on the tire side-
wall.
Only certain types of snow chains have
been tested by the manufacturer of your
MINI, classified as road-safe and recom-
mended. Contact your MINI Dealer for
more details. Their use is only permitted in
pairs on the front wheels on winter tires of
the following types:
>175/65 R 15 M+S
>175/60 R 16 M+S.
When fitting, comply with the manufac-
turer's instructions. With chains, do not
exceed a speed of 30 mph / 50 km/h.
Do not initialize the Flat Tire Monitor
after attaching snow chains to the
tires.
When driving with snow chains, it can be
helpful to switch off the ASC or DSC for a
brief period, refer to page72.<

Safety measures in the event of a
flat:
Park the vehicle as far away from flowing
traffic as possible, and switch on the haz-
ard warning flashers.
Turn the steering wheel to the straight-
ahead wheel position and engage the
steering lock. Engage the parking brake and
shift into 1st or reverse gear – selector lever
in P.
All passengers should be outside the vehi-
cle and well away from your immediate
working area – behind a guardrail, for
instance.
If a portable hazard warning lamp is avail-
able, set it up on the roadside at an appro-
priate distance from the rear of the vehicle.
Comply with all safety guidelines and regu-
lations.<
In the event of a flat tire, different proce-
dures should be followed depending on the
equipment included in your vehicle:
>Vehicles with Run-Flat Tires, refer to
page111
>Vehicles with a space-saver spare tire,
refer to the following section
>Vehicles with MINI Mobility System,
refer to page137.
To change a space-saver spare tire, proceed
as follows:

CHANGING TIRES
9. Pull out the space-saver spare tire
towards the rear underneath the vehi-
cle
10. Position the space-saver spare tire with
the valve facing upwards
11. Unscrew the valve extension from the
valve of the space-saver spare tire
12. Unscrew the dust cap from the exten-
sion and place it on the valve of the
space-saver spare tire.
Due to its different dimensions, the
damaged wheel cannot be placed in
the recess for the space-saver spare tire.<
Driving with the space-saver spare tireDrive cautiously. Do not exceed a speed of
50 mph / 80 km/h.
You must expect changes in vehicle han-
dling such as lower track stability during
braking, longer braking distances and
changes in self-steering properties when
close to the handling limit. These effects
are more pronounced when driving with
winter tires.
Only one space-saver spare tire may
be mounted at one time. Reinstall a
wheel and tire of the original size as soon
as possible.<
Check the tire inflation pressure at
the earliest opportunity and correct it
if necessary. Replace the defective tire as
soon as possible and have the new wheel/
tire assembly balanced.<
Additional safety measures in the
event of a tire change:
Change tires only on a flat, solid and non-
slippery surface.
The vehicle or the jack could slip sideways
on soft or slippery support surfaces, such as
snow, ice, flagstones, etc..
Do not use a wooden block or similar object
as a support base for the jack, as this would
prevent it from extending to its full support
height and reduce its load-carrying capac-
ity.
Do not lie under the vehicle or start the
engine when the vehicle is supported by
the jack – risk of fatal injury.<
Preparing for a tire change
Observe the safety precautions
regarding flat tires on page133.<
1. For vehicles with a space-saver spare
tire:
Place the folding chock behind the front
wheel on the other side of the vehicle;
on downward inclines, place it in front of
this wheel. If the wheel is changed on a
surface with a more severe slope, take
additional precautions to secure the
vehicle from rolling
2. Loosen the lug bolts by a half turn.
