Tire rotation

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 Nm)

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.

► After rotating the tires, check and 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

► Tires should be periodically inspected 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.)

► The use of tires other than those 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.

► The full-size temporary use only spare 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.
