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 e.g.
Nominal width in mm
Aspect ratio in Ξ
Radial belt construction
Rim diameter in inches

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
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.<

3.Screw the lifting handle from the onboard
vehicle tool kit onto the thread.
4.Raise the lifting handle slightly.
5.Squeeze the securing spring.
6.The space-saver spare tire is released and
must be held by the lifting handle.
7.Lower the space-saver spare tire with the
lifting handle.
8.Unscrew the lifting handle.
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 page129.<
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.<
