Tire coding
Knowledge of the labeling on the side of the
tire makes it easier to identify and choose the
right tires.
Tire size
Speed code letter
Q = up to 100 mph or 160 km/h
T = up to 118 mph or 190 km/h
H = up to 131 mph or 210 km/h
V = up to 150 mph or 240 km/h
W = up to 167 mph or 270 km/h
Y = up to 186 mph or 300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of the
US Department of Transportation.
DOT code:
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
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 rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment 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, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.
Traction
The 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 government test sur-
faces 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 trac-
tion tests, and does not include acceleration,
cornering, hydroplaning, or peak traction char-
acteristics.<
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 controlled conditions
on a specified indoor laboratory test wheel. Sus-
tained 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 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 loading, either sep-
arately 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, page114.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Designation for specially reinforced tires.
Tire condition
Inspect your tires regularly for tread wear, signs
of damage and for foreign objects lodged in the
tread. Check the tread depth.
Tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm. At tread depths below 0.12 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
Winter tires
When winter tires wear down past a tread depth
of 0.16 in/4 mm, they become perceptibly less
suitable for winter conditions. In the interest of
safety, new tires should be installed.
Minimum tread depth
Wear indicators in the base of the tread groove
are distributed around the tire's circumference;
the letters TWI, for Tread Wear Indicator, on the
tire's sidewalls identify tires that incorporate
these wear indicators. When tire tread is worn
down to the level of the wear indicators, the
remaining tread depth is 0.063 in/1.6 mm.
Tire damage
Due to low-profile tires, please note that wheels,
tires and suspensions parts are more susceptible
to road hazards and consequential damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immediately
and have wheels and tires thoroughly
checked. To do so, drive carefully to the nearest
MINI Dealer or tire shop that works according to
MINI repair procedures with correspondingly
trained personnel. If necessary, have the vehicle
towed there.
Otherwise tire damage can be extremely dan-
gerous for vehicle occupants and other road
users.<
Tire age
The manufacturing date of tires is contained in
the tire coding:
DOT ... 0309 means that the tire was manufac-
tured in week 3 of 2009.
For various reasons, such as the development of
brittleness, the manufacturer of your MINI rec-

Wheels and tires
114
ommends tire replacement after no more than
6 years, regardless of the actual wear of the
tires.
Run-Flat Tires*
The symbol identifying Run-Flat Tires is a circle
with the letters RSC on the sidewall.
Run-Flat Tires comprise a conditionally self-sup-
porting tire and a special rim. The reinforcement
in the sidewalls ensures that the tire can con-
tinue to be used subject to certain restrictions,
even if depressurized.
For information on continuing to drive with a flat
tire, refer to Indication of a flat tire, page67.
New wheels and tires
Have new wheels and tires mounted only
by your MINI Dealer or a specialized tire
shop that has specially trained personnel work-
ing in accordance with the specifications of the
MINI manufacturer. If this work is not carried out
properly, there is a danger of subsequent dam-
age and related safety hazards. Make sure that
the new wheels are balanced.<
Retreaded tires
The manufacturer of your MINI recom-
mends that you avoid using retreaded
tires, as this could impair driving safety. The
causes for this include potentially different tire
casing structures and often wide variations in
tire age, which can result in a limited service
life.<
Correct wheels and tires
The manufacturer of your MINI recom-
mends 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 dimen-
sions, variations in factors such as manufactur-
ing tolerances can result in contact between tire
and bodywork, ultimately leading to serious
accidents. The manufacturer of your MINI can-
not evaluate non-approved wheels and tires to
determine if they are suited for use, and there-
fore 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 combination for
your vehicle.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS and DSC.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. After a tire has been dam-
aged, mount the previous wheel and tire combi-
nation again as soon as possible.
Wheels with Tire Pressure Monitor
TPM electronics
When mounting new tires or changing over from
summer to winter tires, or vice versa, only use
wheels with TPM electronics; otherwise the Tire
Pressure Monitor may not be able to detect a
puncture, refer to page69. Your MINI Dealer will
be glad to advise you.

Recommended tire brands
For each tire size, the manufacturer of your MINI
recommends certain tire brands. They are
marked with a clearly visible MINI designation
on the sidewall of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Run-Flat Tires*
When mounting new tires or changing over from
summer to winter tires and vice versa, mount
Run-Flat Tires for your own safety. Keep in mind
that no space-saver spare tire is available in the
event of a flat. Your MINI Dealer will be glad to
advise you.
Special characteristics of winter tires
The manufacturer of MINI recommends the use
of winter tires on snowy roads or if temperatures
drop below 457/ +76. Although 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.
Pay attention to speed
Always comply with the speed limit for
the winter tires mounted on your car;
failure to do so could result in tire damage and
accidents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your MINI Dealer can
supply these labels.
Storage
Always store wheels and tires in a cool, dry place
with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres-
sure indicated on the sidewall of the tire.
Swapping wheels among the axles
Depending on the individual use, front and rear
tires may exhibit different wear and tear.
In order to maintain an even wear and tear, the
wheels may be rotated between the axles. Your
MINI Dealer will be glad to advise you.
Always check the inflation pressure after the tire
rotation, if necessary change the pressure.
Snow chains*
Only certain types of fine-link snow chains have
been tested by the manufacturer of your MINI,
classified as road-safe and recommended. Con-
tact your MINI Dealer for more details.
Only attach snow chains in pairs to the front
wheels with the following tires.
>175/65 R 15 M+S
>175/60 R 16 M+S
John Cooper Works:
>185/50 R 17 86 H M+S XL RSC
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph or 50 km/h.
Do not initialize the Flat Tire Monitor if
snow chains are mounted, otherwise the
instrument might issue an incorrect reading.
When driving with snow chains, it can be useful
to briefly deactivate the DSC or activate the DTC,
refer to page65.<

Repairing a flat tire
Safety measures in the event of a break-
down:
Park the vehicle as far as possible from mov-
ing traffic and switch on the hazard warning
flashers.
Turn the steering wheel until the front wheels
are in the straight-ahead position and engage
the steering wheel lock. Engage the parking
brake and shift into 1st or reverse gear or place
the selector lever in position P.
All passengers should be outside the vehicle and
in a safe place, e.g. behind a guardrail.
Erect a warning triangle or warning flasher at the
appropriate distance if necessary. Comply with
all safety guidelines and regulations.<
In the event of a flat tire, different procedures
should be followed depending on the equip-
ment included in your vehicle:

Reinflating the tire
1.Unscrew the dust cap from the tire valve of
the defective tire.
2.Screw connection hose2 onto the tire valve.
3.Insert connector 1 into the lighter socket in
the interior of the vehicle, page88.
4.Switch on the compressor using switch3.
5.Inflate the tire to at least 26 psi/180 kPa and
at most 36 psi/250 kPa.
To check the inflation pressure, switch off
the compressor briefly.
Do not run the compressor for longer
than 6 minutes, otherwise the device
will overheat and possibly be damaged.<
If an air pressure of 26 psi/180 kPa is not
reached:
1.Unscrew connection hose2 and drive the
vehicle forward and backward about 33 ft/
10 m to distribute the liquid sealant in the
tires evenly.
2.Repeat the procedure.
If an inflation pressure of 26 psi/180 kPa
still cannot be reached, the tire is too
heavily damaged. Please contact the nearest
MINI Dealer.<
Distributing liquid sealant
Immediately drive for approx. 10 minutes, so
that the liquid sealant is uniformly distributed.
Do not exceed speeds of 40 mph/
60 km/h.
If possible, do not drop below 10 mph/
20 km/h.<
Checking tire inflation pressure
1.After driving for approx. 10 minutes, pull
over at a suitable location.
2.Screw connection hose2 onto the tire valve.
3.Check the tire inflation pressure.
The tire pressure must be at least
18 psi/130 kPa. If it is not, do not con-
tinue driving.<
If a tire pressure of at least 18 psi/130 kPa is
displayed:
1.Switch on the compressor. Correct the tire
inflation pressure to the specified value,
page104.
2.Replace the tire as soon as possible.
Driving on
Do not exceed the permitted maximum
speed of 50 mph/80 km/h; doing so may
result in an accident.<
Replace the defective tire as soon as possible
and have the new wheel/tire assembly bal-
anced.
Have the Mobility System refilled.
Tire change set
When changing a tire, always observe the safety
measures and the procedure for changing tires
described below.
In case of a flat tire, the tire change set is
not needed due to the availability of the
Mobility System.<

9.Pull the space-saver spare tire underneath
the vehicle out towards the rear.
10.Position the space-saver spare tire with the
valve facing upward.
11.Unscrew the valve extension from the valve
of the space-saver spare tire.
12.Unscrew the dust cap from the extension
and place it on the valve of the space-saver
spare tire.
Due to its different dimensions, the dam-
aged wheel cannot be placed in the recess
for the space-saver spare tire.<
Driving with the space-saver spare tire
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h. Changes may
occur in vehicle handling such as lower track sta-
bility during braking, longer braking distances
and changes in self-steering properties when
close to the handling limit. These properties are
more noticeable with winter tires.<
Only one space-saver spare tire may be
mounted at one time. Mount a wheel and
tire of the original size as soon as possible, to
avoid any safety risks.<
Check the tire inflation pressure at the ear-
liest opportunity and correct it if neces-
sary. Replace the defective tire as soon as possi-
ble and have the new wheel/tire assembly
balanced.<
Preparing for a tire change
Observe the safety precautions regarding
flat tires on page130.<
Additional safety measures when chang-
ing tires: Only change the tire when parked on a surface
that is level, firm and not slippery.
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 capacity.
Do not lie under the vehicle or start the engine
when the vehicle is supported by the jack; other-
wise there is a risk of fatal injury.<
1.Place the foldable chock
* behind the front
wheel on the other side of the vehicle or in
front of the wheel if the vehicle is on an
incline. If the wheel is changed on a surface
with a more severe slope, take additional
precautions to secure the vehicle from
rolling.
2.Uncover the lug bolts if necessary.
If the wheel is equipped with a hub cover,
pry it off using the screwdriver from the tire
change kit.
3.Loosen the lug bolts by a half turn.
Jacking up the vehicle
The vehicle jack is designed for changing
wheels only. Do not attempt to raise
another vehicle model with it or to raise any load
of any kind. To do so could cause accidents and
personal injury.<
1.Place the jack at the jacking point closest to
the wheel.
