Tire. Repair procedures

Tire Wear
  
Using tires and wheel other than the recommended sizes could cause unusual handling characteristics and poor vehicle control, resulting in a serious accident.
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(0.0630 in), the wear indicators (B) will appear.

Tire Rotation
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.

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 .

  
The tire bead should be broken approx. 90° from the valve side of the wheel. The bead breaker should not be set too deep.
Avoid tire/tool contact with the valve on dismount.
Dismount should end near the valve.
3.
Rotate the wheel clockwise.

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.

4.
After bottom bead is on tire, rotate the rim until the valve is at the 5 o’clock position relative to the head on the tire changing machine. 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 both beads seat.
Recommended Tire pressure :
240 kPa (35 psi)

Wheel. Repair procedures

Hub nut tightening sequence
1.
Tighten the hub nuts as follows.
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.
  
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 illustration below.
Run - out
Aluminum
Radial mm (in.)
Below 0.3 (0.0118)
Lateral mm (in.)
Below 0.3 (0.0118)

3.
If measured value exceeds the standard value, replace the wheel.

Alignment. Repair procedures

Front Wheel Alignment
  
When using a commercially available computerizedwheel alignment equipment to inspect the front wheelalignment, always position the vehicle on a levelsurface with the front wheels facing straight ahead.
Prior to inspection, make sure that the frontsuspension and steering system are in normaloperating condition and that the tires are inflated tothe specified pressure.
Toe

B - A > 0 : Toe in
B - A < 0 : Toe out
Toe adjustment
1.
Loosen the tie rod end lock nut.
2.
Remove the bellows clip to prevent the bellows frombeing twisted.
3.
Adjust the toe by screwing or unscrewing the tie rod.Toe adjustment should be made by turning the rightand left tie rods by the same amount.
Toe
Total : 0.1° ± 0.2°
Individual : 0.05° ± 0.1°

4.
When completing the toe adjustment, install thebellows clip and tighten the tie rod end lock nut tospecified torque.
Tightening torque :
49.0 - 53.9 N.m (5.0 - 5.5 kgf.m, 36.2 - 39.8 lb-ft)
Camber
Camber : -0.5° ± 0.5°
When the wheel tilts out at the top, then the camber ispositive (+). When the wheel tilts in at the top, then the camber isnegative (-). Camber and Caster are pre-set at the factory, so they donot need to be adjusted. If the camber and caster are notwithin the standard value, replace or repair the damagedparts and then inspect again.

ITEM
Description
A
Positive camber angle
B
True vertical
C
Strut centerline

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 : 4.34° ± 0.5°

King-pin angle
King-pin : 13.8° ± 0.5°

  
The worn loose or damaged parts of the front suspension assembly must be replaced prior to measuring front wheel alignment.
Caster are pre-set to the specified value at the factory and don't need to be adjusted.
If the caster are not within specifications, replace bent or damaged parts.
The difference of left and right wheels about the the caster must be within the range of 0° ± 0.5°.
Rear Wheel Alignment
  
When using a commercially available computerized wheel alignment equipment to inspect the rear wheel alignment, always position the vehicle on a level surface.
Prior to inspection, make sure that the rear suspension system is in normal operating condition and that the tires are inflated to the specified pressure.
