TIRE CONDITION TIRE REPLACEMENTTire tread/tire damageInspect your tires frequently for tread wear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.
The tread depth should not fall below1/8 in / 3 mm.
Below
1/8 in / 3 mm tread pattern depth,
there is an increased risk of hydroplaning,
even at relatively moderate speeds and
with only small amounts of water on the
road.
Wear indicators in the tread-groove base,
see arrow, are spread around the circum-
ference of the tire and are marked on the
side wall of the tire with TWI – Tread Wear
Indicator. The indicators in the tread indi-
cate at 1/16 in / 1.6 mm tread depth that
the legally permitted wear limit has been
reached.
Never continue to drive with a flat,
pressureless tire, except with Run Flat
tires. A pressureless, flat tire greatly
impairs steering and braking response, and
can lead to complete loss of control over
the vehicle. Avoid overloading the vehicle
so that the permitted load on the tires is
not exceeded. Overloading can lead to
overheating and increases the rate at
which damage develops inside the tires.
The ultimate result can assume the form of
a sudden air loss.
Unusual vibrations while driving, caused
for example by driving over a curb or simi-
lar, can indicate wheel or tire damage or
other damage to the vehicle. This is also
true for irregularities in the vehicle's han-
dling characteristics, such as a pronounced
tendency to pull to the left or right. Should
this occur, respond by immediately reduc-
ing your speed. Proceed carefully to the
nearest MINI Dealer or professional tire
center, or have the vehicle towed there to
have its wheels and/or tires inspected or
controlled. Tire damage – up to and includ-
ing blowouts – can endanger the lives of
both the vehicle occupants and other road
users.<
To maintain good handling and vehicle
response, use only tires of a single tread
configuration from a single manufacturer.
The manufacturer of your MINI tests and
approves wheel and tire combinations.
Do not use retreaded tires, since driv-
ing safety may be impaired. This is
due to the possible variations in casing
structures and, in some cases, to their
extreme age, which can lead to a decrease
in their durability. Traction AA A B C
Temperature A B C
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.<

TIRE REPLACEMENT Tread wearThe 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
one and one-half – 1 γ – 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.TractionThe traction grades, from highest to lowest,
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.<
TemperatureThe 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 a sudden flat tire. 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 fai-
lure.<
Uniform Tire Quality Grading Quality 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 ATire age The date on which the tire was manufac-
tured is indicated by the code on the side-
wall:
DOT ... 1202 indicates that the tire was
manufactured in Week 12 of the year 2002.
The manufacturer of your MINI recom-
mends replacing all tires – including the
space-saver tire, regardless of actual wear –
after 6 years at the latest.Run Flat tires
For replacement, use only Run Flat
tires, as in the event of a flat tire
there is no space-saver spare tire.
You will recognize Run Flat tires by a circu-
lar symbol containing the letters RSC on
the side of the tire, see pages 85, 116.<

WHEEL AND TIRE COMBINATIONS WINTER TIRESThe right choiceThe factory-approved normal and Run Flat
tires are matched to your vehicle and have
been selected to provide optimum safety
and driving comfort if used properly.
The manufacturer of your MINI rec-
ommends never mounting wheels
and tires that have not been specifically
approved by the manufacturer 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, ulti-
mately leading to serious accidents. The
manufacturer of your MINI cannot evaluate
non-approved wheels and tires to deter-
mine if they are suited for use, and there-
fore cannot ensure the operating safety of
the vehicle if they are fitted.<
The manufacturer of your MINI has tested
certain tire brands in each size, categorized
them as safe for use on the road, and
approved them. Contact your MINI Dealer
for more details.
The correct wheel and tire combina-
tion affects various systems that
would otherwise be impaired, e.g. ABS,
ASC+T and DSC. For this reason, use only
tires of the same manufacture and tread
configuration. In the event of a flat tire, for
example, remount the approved wheel and
tire combination as soon as possible.<
StorageStore tires in a cool, dry place, protecting
them against light whenever possible.
Protect the tires against contact with oil,
grease and fuel.
Choosing the right tireThe manufacturer of your MINI recom-
mends winter tires – M+S radial tires – for
driving in adverse winter road conditions.
While so-called all-season tires with M+S
designation provide better winter traction
than summer tires with the load ratings S,
T, H, V, W, they do not achieve the perfor-
mance of winter tires.
In the interest of safe tracking and steering
response, install winter tires made by the
same manufacturer having the same tread
configuration on all four wheels.
Before purchasing winter tires, check
whether your MINI is fitted with Run Flat
tires. You will recognize Run Flat tires by a
circular symbol containing the letters RSC
on the side of the tire, see page 116. In this
case, use only Run Flat tires, as in the event
of a flat tire there is no space-saver spare
tire.
Any MINI Dealer will be glad to advise you
on the selection of the right winter tires for
the relevant operating conditions.

WINTER TIRES SNOW CHAINS
*
Observing speeds
Never exceed the maximum speed
for which the tires are rated.
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and accidents.
Have this work performed by skilled profes-
sionals only. Your MINI Dealer will be glad
to assist you with both their expertise and
the proper equipment for your vehicle.<
Tire condition, tire inflation pressure
Below a tread depth of
3/16 in /
4 mm, winter tires display a percepti-
ble 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.
Only certain types of snow chains have
been tested by the manufacturer of your
MINI, classified as road-safe and approved.
Contact your MINI Dealer for more details.
The manufacturer of your MINI recom-
mends that you use these fine-link snow
chains only. Their use is only permitted in
pairs on the front wheels on winter tires of
the following type:
175/65 R 15.
When fitting, comply with the manufac-
turer's instructions. With chains, do not
exceed a speed of 30 mph / 50 km/h.
After fitting the snow chains, do not
activate the Flat Tire Monitor.
When driving with snow chains, it can be
helpful to switch off the ASC+T or DSC for a
brief period, see pages 62, 63.<

WASHER FLUID ENGINE OILHeadlamp* and windshield washer
systemsThe capacity of the headlamp washer sys-
tem is approx. 2.6 quarts / 2.5 liters, that of
the windshield washer system approx.
2.1 quarts / 2.0 liters.
Fill with water and – if required – with anti-
freeze, according to manufacturer's recom-
mendations.
We recommend that you mix the
washer fluid before adding it to the
reservoir.<
Antifreeze agent for the washer sys-
tems is flammable. Always keep it
well away from sparks and open flames,
and store it in tightly closed containers well
out of the reach of children. Always observe
the instructions for use provided on the
container.<
The illustration shows as an example the
dipstick of the MINI COOPER.Measuring the oil level 1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating temperature
3. Pull the dipstick out after approx.
5 minutes and wipe it off with a lint-free
cloth, paper towel, or similar material
4. Carefully push the dipstick all the way
into the guide tube and pull it out again.
The oil level must be between the two
marks on the dipstick.
As with fuel economy, oil consumption is
directly influenced by your driving style and
vehicle operating conditions.
