Declaration according to NHTSA/FMVSS
138 Tire Pressure Monitoring Systems
Each tire, including the spare, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the vehi-
cle placard or tire inflation pressure label, you
should determine the proper tire inflation pres-
sure for those tires. As an added safety feature,
your vehicle has been equipped with a tire pres-
sure monitoring system TPMS that illuminates a
low tire pressure telltale when one or more of
your tires are significantly under-inflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping
ability. Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire
pressure, even if underinflation has not reached
the level at which the TPMS low tire pressure tell-
tale illuminates.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously lit. This sequence will continue
upon subsequent vehicle startups as long as the
malfunction exists. When the malfunction indi-
cator is illuminated, the system may not be able
to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction telltale
after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.

Information for your safety
It is not merely the tires' service life, but also driv-
ing comfort and, to a great extent, driving safety
that depend on the condition of the tires and the
maintenance of the specified tire pressure.
Checking pressure
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail to
observe this precaution you may be driving on
tires with incorrect tire pressures, a condition that
can not only compromise your vehicle's driving
stability, but also lead to tire damage and the risk
of an accident. Do not drive with deflated, i.e. flat
tires, except when using Run-Flat Tires. A flat tire
will seriously impair your vehicle's handling and
braking response. Attempts to drive on a flat tire
can lead to loss of control over the vehicle.<
Check the tire inflation pressures only on
cold tires. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure is higher.
After adjusting the tire inflation pressure,
reinitialize the flat tire monitor, page65,
or reset the tire pressure control, page67.<

A valve extension for checking the inflation pres-
sure is located behind the bumper.
Inflation pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The tire inflation pressures apply to the
tire sizes approved and the tire brands
recommended by the manufacturer of your
MINI. Your MINI Dealer will be glad to advise
you.<
For correct identification of the right tire infla-
tion pressures, observe the following:
>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up to
100 mph or 160 km/h
For normal driving speeds of up to 100 mph or
160 km/h and to achieve optimum driving com-
fort, adjust pressures to the respective tire infla-
tion pressures listed on the following pages in
the columns for traveling speeds up to a maxi-
mum of 100 mph or 160 km/h.
These tire inflation pressures can also be found
on the driver's-side door post when the driver's
door is open.
The maximum permissible speed for these
tire pressures is 100 mph or 160 km/h. Do
not exceed this speed, otherwise tire damage
and accidents could occur.<

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 traction
tests, and does not include acceleration, corner-
ing, hydroplaning, or peak traction characteris-
tics.<
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

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 acci-
dents.<
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. Spe-
cialist tire dealers and your MINI Dealer can sup-
ply 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
MINI 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 page64.<
