2010 INFINITI M tire size

As soon as possible, tighten the wheel
nuts to the specified torque with a torque
wrench.Wheel nut tightening torque:80 ft-lb (108 N´m)
The wheel nuts must be kept tightened to
the specification at all times. It is recom-
mended that wheel nuts be tightened to
the specification at each tire rotation in-
terval.
WARNING
cAfter rotating the tires, check and ad-
just the tire pressure.
cRetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
cDo not include the spare tire or any
other small size spare tire in the tire
rotation.
cFor additional information regarding
tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-
formationº (Canada) in the Warranty
Information Booklet.

Tire wear and damage
WARNING
cTires should be periodically in-
spected for wear, cracking, bulging or
objects caught in the tread. If exces-
sive wear, cracks, bulging or deep
cuts are found, the tire(s) should be
replaced.

cThe original tires have built-in tread
wear indicators. When wear indica-
tors are visible, the tire(s) should be
replaced.
cTires degrade with age and use. Have
tires, including the spare, over 6
years old checked by a qualified tech-
nician, because some tire damage
may not be obvious. Replace the tires
as necessary to prevent tire failure
and possible personal injury.
cImproper service of the spare tire may
result in serious personal injury. If it
is necessary to repair the spare tire,
contact an INFINITI retailer.
cFor additional information regarding
tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-
formationº (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. (See ªSPECIFICATIONSº
in the ª9. Technical and consumer informationº
section for recommended types and sizes of
tires and wheels.)
WARNING
c The use of tires other than those recom-
mended or the mixed use of tires of different
brands, construction (bias, bias-belted or ra-
dial), or tread patterns can adversely affect
the ride, braking, handling, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration, head-
light aim and bumper height. Some of these
effects may lead to accidents and could re-
sult in serious personal injury. c
If the wheels are changed for any reason,
always replace with wheels which have the
same off-set dimension. Wheels of a differ-
ent off-set could cause premature tire wear,
degrade vehicle handling characteristics
and/or interference with the brake
discs/drums. Such interference can lead to
decreased braking efficiency and/or early
brake pad/shoe wear. See ªWHEELS AND
TIRESº in the ª9. Technical and consumer
informationº section of this manual for
wheel off-set dimensions.
c When a spare tire is mounted or a wheel is
replaced, tire pressure will not be indicated,
the TPMS will not function and the low tire
pressure warning light will flash for approxi-
mately 1 minute. The light will remain on
after 1 minute. Contact your INFINITI retailer
as soon as possible for tire replacement
and/or system resetting.
c Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
c Do not install a damaged or deformed wheel
or tire even if it has been repaired. Such
wheels or tires could have structural damage
and could fail without warning.
c The use of retread tire is not recommended.

cFor additional information regarding tires,
refer to ªImportant Tire Safety Informationº
(US) or ªTire Safety Informationº (Canada) in
the Warranty Information Booklet.
All-Wheel Drive (AWD) models
CAUTION
cAlways use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Failure to do so may result in a circumference
difference between tires on the front and
rear axles which will cause excessive tire
wear and may damage the transmission,
transfer case and differential gears.
c ONLY use spare tires specified for the AWD
model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with tires
of the same size, brand, construction and tread
pattern. The tire pressure and wheel alignment
should also be checked and corrected as nec-
essary. Contact an INFINITI retailer.
Wheel balance
Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can
get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be performed with
the wheels off the vehicle. Spin balancing the
wheels on the vehicle could lead to mechanical
damage.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada) in the
INFINITI Warranty Information Booklet.
Care of wheels
c Wash the wheels when washing the vehicle
to maintain their appearance.
c Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
c Do not use abrasive cleaners when washing
the wheels.
c Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead. c
INFINITI recommends that the road wheels
be waxed to protect against road salt in
areas where it is used during winter.
Spare tire (TEMPORARY USE ONLY
spare tire)
Observe the following precautions if the TEM-
PORARY USE ONLY spare tire must be used,
otherwise your vehicle could be damaged or
involved in an accident.
WARNING
cThe TEMPORARY USE ONLY spare tire should
be used for emergency use. It should be re-
placed with the standard tire at the first op-
portunity to avoid possible tire or differen-
tial damage.
c Drive carefully while the TEMPORARY USE
ONLY spare tire is installed. Avoid sharp
turns and abrupt braking while driving.
c Periodically check spare tire inflation pres-
sure. Always keep the pressure of the TEM-
PORARY USE ONLY spare tire at 60 psi
(420 kPa, 4.2 bar). Always keep the pressure
of the full size spare tire (if so equipped) at
the recommended pressure for standard
tires, as indicated on the Tire and Loading
Information label.
