Infiniti QX: Changing wheels and tires
Tire rotation
INFINITI recommends rotating the tires every 7,500 miles (12,000 km). (See “Flat tire” in the “6. In case of emergency” section for tire replacing procedures.)
As soon as possible, tighten the wheel nuts to the specified torque with a torque wrench. Wheel nut tightening torque: 898 ft-lb (133 N·m)
The wheel nuts must be kept tightened to the specification at all times. It is recommended that wheel nuts be tightened to the specification at each tire rotation interval.
WARNING
► After rotating the tires, check and
adjust the tire pressure.
► Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
► Do not include the full-size temporary
use only spare tire (if so
equipped) in the tire rotation.
► For additional information regarding
tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in
the Warranty Information Booklet.

Tire wear and damage
WARNING
► Tires should be periodically inspected
for wear, cracking, bulging
or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced.
► The original tires have built-in
tread wear indicators. When wear
indicators are visible, the tire(s)
should be replaced.
► Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
► Improper service of the spare tire
may result in serious personal
injury. If it is necessary to repair
the spare tire, contact an INFINITI
retailer.
► For additional information regarding
tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (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 “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
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted or radial), or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-tire
clearance, tire chain clearance, speedometer
calibration, headlight aim and
bumper height. Some of these effects
may lead to accidents and could result 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 different 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 remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement 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.
Four-wheel Drive (4WD) models
CAUTION
► Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), 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
4WD model.
If excessive tire wear is found, it is recommended 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 necessary. 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. Appearance and care” section for details about care of the wheels.
Spare tire
When a spare tire is mounted (TEMPORARY USE ONLY or conventional), the TPMS will not function. Spare tire (FULL-SIZE TEMPORARY USE ONLY spare tire) (Applies ONLY to vehicles equipped with P275/50R22 tires): Observe the following precautions if the full-size temporary use only spare tire must be used, otherwise your vehicle could be damaged or involved in an accident.
WARNING
► The full-size temporary use only 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 spare tire is
installed. Avoid sharp turns and abrupt
braking while driving. The vehicle driving
performance may be affected when
driving on wet or snow covered roads.
► When the spare tire is installed, the
following systems may not work correctly.
— Tire Pressure Monitoring System
(TPMS)
— Vehicle Dynamic Control (VDC) System
► Periodically check spare tire inflation
pressure. Always keep the spare tire
inflated to the pressure specification
shown on the Tire and Loading Information
label. For Tire and Loading Information
label location, see “Tire and Loading
Information label” in the index of this
manual.
► With the 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 spare tire should be
used on the front wheels and original
tire used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
► Do not use the spare tire on other
vehicles.
► Do not use more than one spare tire at
the same time.
CAUTION
Do not use tire chains on the spare tire. Tire
chains will not fit properly and may cause
damage to the vehicle.
