Tire

Repair procedures
Tire Wear
1.
Measure the tread depth of the tires.
Tread depth [limit] : 1.6 mm (0.0630 in.)
2.
If the remaining tread depth (A) is less than the limit, replace the tire.
   
•
When the tread depth of the tires is less than 1.6 mm(0.063 in), the wear indicators (B) will appear.

Removal
1.
Remove valve core and deflate the tire.
2.
Remove the side of the tire bead area from the wheel using tire changing machine .

   
•
Check that the bead breaker is sufficiently spaced from the TPMS sensor.
•
Beads are removed at 90, 180, and 270 degrees from the valve.
3.
Rotate the wheel clockwise.

   
•
Position the TPMS sensor at 12 o'clock from the head of the tire changer.
•
Do not impact the sensor when lifting the bead with a lever.
Installation
1.
Apply tire soap or lubrication to the top and bottom tire beads.
   
•
When changing the wheel, do not reuse the snap-in type TPMS sensor.

2.
To fit the bottom bead, position the valve at the 5 o’clock position relative to the head on the tire changing machine.

3.
Place the tire on the rim so the bottom bead touches the edge of the rim after the valve (6 o’clock). Rotate the rim clockwise, and push down on the tire at the 3 o’clock position to fit bottom bead.

   
•
Reach the tire on the wheel so that the beads touch the rim edge (6 o'clock) behind the sensor.
4.
Push down on the tire at the 3 o’clock position and rotate the rim clockwise to fit the top bead.

5.
Inflate the tire until beads seat.
Recommended Tire pressure : Refer to "Specification"

Tire Rotation
Replace the tire in the direction of the arrow shown in the figure.

Checking For Pull And Wander
If the steering pulls to one side, rotate the tires according to the following wheel rotation procedure.
1.
Rotate the front right and front left tires, and perform a road test in order to confirm vehicle stability.

2.
If the steering pulls to the opposite side, rotate the front and rear tires, and perform a road test again.

3.
If the steering continues to pull to one side, rotate the front right and left tires again, and perform a road test.

4.
If the steering continues to pull to the opposite side, replace the front wheels with new ones.

Wheel

Components and components location
Components
Steel wheel 15 inch (6.0J X 15)
Aluminum wheel 15 inch (6.0J X 15)

Aluminum wheel 16 inch (6.5J X 16)
Aluminum wheel 17 inch (7.0J X 17)


Repair procedures
Hub nut tightening sequence
1.
Tightening torque
Tightening torque:
107.9 - 127.5 N.m (11.0 - 13.0 kgf.m, 79.6 - 94.0 lb-ft)
   
•
When using an impact gun, final tightening torque should be checked using a torque wrench.
2.
Tighten all wheel nuts evenly according to the tightening sequence until fully tightened.

   
If the vehicle starts within 19 minutes after the replacement of the wheel of the stopped vehicle, the TPMS Malfunction Indicator on the instrument cluster illuminates.
–
The above symptom is due to communication failure between the BCM and the replaced TPMS ID.
–
This communication failure indicator turns off in 19 minutes after the vehicle stops through the BCM’s automatic learning process of TPMS ID.
(When driving the vehicle after stopping for over 19 minutes, the indicator turns off automatically.)
Run out inspection
1.
Jack up the vehicle.
2.
Measure the wheel run-out by using a dial indicator as shown below.
Limit
Radial
Axial
Run-out mm (in.)
Steel wheel
0.6 (0.0236)
0.8 (0.0315)
Aluminum wheel
0.3 (0.0118)
0.3 (0.0118)

3.
If measured value run-out the standard value, replace the wheel.

Alignment

Repair procedures
Inspection
Front Alignment
When using a wheel alignment tester to check the alignment of the wheels, make sure that the vehicle is horizontal and the front wheels are pointing straight ahead. Make sure that the suspension and steering equipment are normal, the wheels are straight.

Camber
Camber refers to the tilt of the center of the wheel.
Camber angle
(N.A / CHINA) : -0.56° ± 0.5°
(DOM / AUS) : -0.5° ± 0.5°
(GEN / M.E / EU / RUS) : -0.37° ± 0.5°
(BRZ / MEXICO) : -0.30° ± 0.5°

•
The worn loose or damaged parts of the front suspension assembly must be replaced prior to measuring front wheel alignment.
•
Camber and caster are pre-set to the specified value at the factory and don't need to be adjusted.
•
If the camber and caster are not within specifications, replace bent or damaged parts.
•
The difference of left and right wheels about the the camber and caster must be within the range of 0° ± 0.5°.
Caster
Caster is the tilting of the strut axis either forward or backward from vertical. A backward tilt is positive (+) and a forward tilt is negative (-).
Caster is pre-set at the factory and doesn't need to be adjusted. If the caster is not within the standard value, replace the bent or damaged parts.
Caster : 4.55° ± 0.5°

Rear Wheel Alignment
When using a wheel alignment tester to check the alignment of the wheels, make sure that the vehicle is horizontal and the front wheels are pointing straight ahead. Make sure that the suspension and steering equipment are normal, the wheels are straight.
