Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. (See “SPECIFICATIONS”
in the “9. Technical and consumer information”
section for recommended types and sizes of
tires and wheels.)
WARNING
●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. ●
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 “WHEELS AND
TIRES” in the “9. Technical and consumer
information” section of this manual for
wheel off-set dimensions.
● When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
● 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.
● The use of retread tire is not recommended. ●
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Intelligent All-Wheel Drive (AWD)
models
CAUTION
● Always 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.
● ONLY use spare tires specified for the Intel-
ligent 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 “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
INFINITI Warranty Information Booklet.
Care of wheels
See “CLEANING EXTERIOR” in the “7. Appear-
ance and care” section for details about care of
the wheels.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire)
Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident.
WARNING
●The T-type spare tire should be used for
emergency use. It should be replaced with
the standard tire at the first opportunity to
avoid possible tire or differential damage.
● Drive carefully while the TEMPORARY USE
ONLY spare tire is installed. Avoid sharp
turns and abrupt braking while driving.
● 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 Infor-
mation label. For Tire and Loading Informa-
tion label location, see “Tire and Loading
Information label” in the index of this
manual.
● With the TEMPORARY USE ONLY spare tire
installed do not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
● When driving on roads covered with snow or
ice, the TEMPORARY USE ONLY spare tire
should be used on the front wheels and origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the two rear
original tires. ●
Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than the
standard tire. Replace the spare tire as soon
as the tread wear indicators appear.
● Do not use the spare tire on other vehicles.
● Do not use more than one spare tire at the
same time.
● Do not tow a trailer when the TEMPORARY
USE ONLY spare tire is installed.
CAUTION
● Do not use tire chains on a TEMPORARY USE
ONLY spare tire. Tire chains will not fit prop-
erly and may cause damage to the vehicle.
● Because the TEMPORARY USE ONLY spare
tire is smaller than the original tire, ground
clearance is reduced. To avoid damage to the
vehicle, do not drive over obstacles. Also do
not drive the vehicle through an automatic
car wash since it may get caught.
