Since the possible driving distance depends to a
considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, exter-
nal temperature, vehicle load, etc.
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g.
reduced lane stability during braking, a longer
braking distance and altered self-steering
properties. <
Vibrations or loud no ises while driving can
indicate complete failure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, pieces of tire may come off,
which could result in an accident. Do not con-
tinue driving and contac t your MINI dealer.<

> Malfunction because of other equipment or
devices, same radio frequency:
After leaving the interference area, the
system is again active automatically.
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 yo ur 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 telltal e when one or more of
your tires are significantly underinflated.
Accordingly, when the low tire pressure telltale
illuminates, you should st op and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
underinflated 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 underi nflation has not reached
the level at which the TPMS low tire pressure
telltale illuminates.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunct ion, the telltale will
flash for approximately one minute and then
remain continuously lit. This sequence will con-
tinue upon subsequent vehicle startups as long
as the malfunction exists. When the malfunction
indicator 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, includ ing the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction

Information for your safety
It is not merely the tires' service life, but also
driving 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 precauti on you may be driving
on tires with incorrect ti re pressures, a condition
that can not only compromise your vehicle's
driving stability, but also l e a d t o t i r e d a m a g e a n d
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.
Att empt s to drive o n a flat t ire can lead to lo ss 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 hou rs. When tires are warm,
the tire inflation pressure is higher.
After adjusting the tire inflation pressure,
reinitialize the flat tire monitor, page 70,
or reset the Tire Pressure Monitor, page 72.<

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 CAll 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 co urse as a tire graded
100. The relative performance of tires depends
upon the actual conditio ns 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 incl ude acceleration, corner-
ing, hydroplaning, or pe ak 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 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 corre sponds to a level of
performance which all pa ssenger 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 overlo aded. 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 144.

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 roads during the winter, or if
temperatures drop below 45 7/ +7 6.
Although all-season M+S tires provide better
winter traction than summer tires, they gener-
ally 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 ti res, 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 diff erent 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 fi ne-link snow chains have
been tested by the manufacturer of your MINI,
classified as road-s afe and recommended.
Contact 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 page 68.<
