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 (1 γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditio ns of their use, how-
ever, and may depart si gnificantly 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 con-
trolled conditions on specified 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 trac-
tion tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics. <
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 labo ratory 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 lev-
els of performance on the laboratory test wheel
that exceed 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 combin ation, 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, page 218.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
XL
Designation for specia lly reinforced tires.
Tire condition
Inspect your tires regularly for tread wear, signs
of damage and for foreig n objects lodged in the
tread. Check the tread depth.

Tread depth
The tread depth should not drop below 1/8 in/
3 mm, although, for example, European
legislation only specifies a minimum tread depth
of 1/16 in/1.6 mm. At tr ead depths below 1/8 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 1/6 in/4 mm, they become perceptibly less
suitable for winter condit ions. 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 dept h is 1/16 in/1.6 mm.
Tire damage
Driving over rough or damaged road surfaces, as
well as debris, curbs, and other obstacles can
cause serious damage to wheels, tires, and sus-
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed,
especially if your vehicle is equipped with low-
profile tires. Unusual vibrations encountered during normal
vehicle operation can indi
cate tire failure or
some other vehicle defect . This can, for exam-
ple, be caused by drivin g 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 a specialized tire shop that has
specially trained personnel working in accor-
dance with the specifications of the MINI
manufacturer. If necessa ry, have the vehicle
towed there.
Otherwise, tire damage can be extremely dan-
gerous for vehicle occu pants and other road
users. <
Tire age
The manufacturing date of tires is contained in
the tire coding:
DOT ... 0312 means that the tire was manufac-
tured during the 3rd week of 2012.
For various reasons, such as the development of
brittleness, the manufacturer of your MINI rec-
ommends tire replacemen t 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, page88.
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 th e specifications of the
MINI manufacturer. If this work is not carried out
properly, there is a danger of subsequent dam-
age and related safety ha zards. 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 of ten 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 su ited 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 an d 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
damaged, mount the previous wheel and tire
combination 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 page 90. 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 ow n 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 your MINI recommends the
use of winter tires on snowy roads or if temper-
atures drop below 457/ +7 6. 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. This
label is available at your tire dealer or MINI
dealer.
Storage
Always store wheels and tires in a cool, dry place
with as little exposure to light as possible.
Always protect tires agains t all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation
pressure 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.
Contact your MINI deal er 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 ch ains, it can be useful
to briefly deactivate DSC or activate DTC, refer to
page 84.<

CareMOBILITY
229
When attempting to remove stains from
the convertible top, do not use spot
removers, paint thinners, solvents, gasoline, or
similar fluids. These cleaners may damage the
rubber seals. The improper care or cleaning
methods may cause the convertible top and its
seams to leak.<
Use special convertible top cleaning agents if
attempting to re move heavy stains.
Always read and foll ow the manufacturer's
instructions.
Use an impregnating agent to treat the convert-
ible top once a year.
MINI Coupe, MINI Roadster: rear spoiler
compartment
So that the operation of the rear spoiler is not
compromised, e.g., by leaves, snow or ice,
clean the rear spoiler compartment at regular
intervals.
Paintwork, care
Regular care helps your vehicle retain its value
and protects the paint from the long-term
effects of aggre ssive substances.
Environmental influences in areas with
increased air pollution or natural contaminants,
such as tree sap or pollen, can affect the vehicle
paintwork. It is therefor e important to adjust the
frequency and extent of vehicle care corre-
spondingly.
Immediately remove any pa rticularly aggressive
substances, such as fuel that has overflowed, oil,
grease, brake fluid, or bi rd droppings; otherwise,
paint damage can be caused.
Removing paintwork damage
Depending on the severity of the damage,
immediately repair stone damage or
scratches to prevent rusting. <
The manufacturer of the MINI recommends
repairing paint damage pr ofessionally according
to factory specifications with original MINI
paints.
Preservation
Preservation is necessary when water no longer
beads on the clean paint surface. To preserve
the paint, only use pres ervatives that contain
carnauba or synthetic waxes.
Rubber seals
Only treat with water or rubber care products.
Do not use silicon spra ys or other silicon-
containing care products on rubber seals;
otherwise, noise and damage could occur. <
Chrome parts
Carefully clean vehicle parts such as the radiator
grill and door handles with copious quantities of
water and, if necessary, a shampoo additive,
especially when contaminated with road salt.
For additional treatment, use chrome polish.
Light alloy wheels
The system produces brake dust that collects on
the light alloy wheels. Clean them regularly with
acid-free wheel cleaner.
Do not use aggressive, acid-containing,
highly alkaline, or abrasive cleansers or
steam jets hotter than 140 7/60 6 as they may
cause damage. <
External sensors
Keep the outside sensors on the vehicle
such as the Park Di stance Control clean
and ice-free to ensure that they function
properly. <
Internal care
Upholstery/fabrics
Regularly use a vacuum cleaner to remove
surface dirt.
In case of serious spots such as liquid stains, use
a soft sponge or lint-free microfiber cloth and
suitable interior cleane rs. Observe the instruc-
tions on the packaging.
