TIRE AND WHEEL SYSTEM INSPECTION

PROCEDURE


  1. INSPECT TIRES


    1. Inspect the tires for wear and proper inflation pressure.

      Cold Tire Inflation Pressure
      Area Tire Size Cold Tire Inflation Pressure
      Front Rear
      Korea 225/45R17 91V

      250 kPa (2.5 kgf/cm2, 36 psi)*1

      280 kPa (2.8 kgf/cm2, 41 psi)*2

      225/40R18 88W

      255/35R18 90W

      250 kPa (2.5 kgf/cm2, 36 psi)*3

      290 kPa (2.9 kgf/cm2, 42 psi)*4
      except Korea

      225/45R17 91W

      225/45RF17 91W

      250 kPa (2.5 kgf/cm2, 36 psi)*3

      290 kPa (2.9 kgf/cm2, 42 psi)*4

      225/40R18 88Y

      255/35R18 90Y

      250 kPa (2.5 kgf/cm2, 36 psi)*5

      260 kPa (2.6 kgf/cm2, 38 psi)*6

      *1: For driving at under 160 km/h (100 mph)

      *2: For driving at over 160 km/h (100 mph)

      *3: For driving at under 190 km/h (118 mph)

      *4: For driving at over 190 km/h (118 mph)

      *5: For driving at under 220 km/h (137 mph)

      *6: For driving at over 220 km/h (137 mph)

    2. A01MZ24

      Using a dial indicator, check the runout of the tires.

      Maximum Tire Runout
      1.0 mm (0.0394 in.)

  2. ROTATE TIRES


    1. A01MXKUC01
      *A for 17 Inch Wheel
      *B for 18 Inch Wheel
      B003WAF Front

      Rotate the tires as shown in the illustration.

      Torque:
      Axle hub nut
      103 N*m  { 1050 kgf*cm, 76 ft.*lbf }

  3. INSPECT AND ADJUST WHEEL BALANCE


    1. A01MWN4C01
      *a 25 mm (0.984 in.)

      Inspect and adjust the off-the-car balance.

      Maximum Imbalance
      8.0 g (0.0176 lb)

      Note


      • Use a cleaning detergent to remove dirt, oil and water from the surface where the balance weight is to be adhered.

      • Do not touch the adhesive surface of the balance weight.

      • Adhere a stick-on type balance weight to the flat surface*a shown in the illustration.

      • Push the balance weight with your finger to securely adhere it to the desired position.

      • Do not reuse balance weights.

      • Use only LEXUS genuine stick-on type balance weights or equivalent.

      Tech Tips


      • Use stick-on type balance weights for both the inner and outer side.

      • If the tires vibrate even after the off-the-car balance adjustment, adjust the wheel balance with on-the-car balancing as necessary.
