TIRE AND WHEEL SYSTEM INSPECTION

PROCEDURE


  1. INSPECT TIRES


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

      Cold Tire Inflation Pressure
      Tire Size Cold Tire Inflation Pressure
      Front Rear
      205/55R16 91W

      260 kPa (2.6 kgf/cm2, 38 psi)*1

      250 kPa (2.5 kgf/cm2, 36 psi)*2

      270 kPa (2.7 kgf/cm2, 39 psi)*3

      225/45R17 91W

      225/45RF17 91W

      290 kPa (2.9 kgf/cm2, 42 psi)*1

      250 kPa (2.5 kgf/cm2, 36 psi)*2
      225/40R18 88Y

      250 kPa (2.5 kgf/cm2, 36 psi)

      		 -
      255/35R18 90Y -

      250 kPa (2.5 kgf/cm2, 36 psi)

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

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

      *3: With ECO tire pressure label: ECO pressure

    2. A01MT5H

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

      Maximum Tire Runout
      1.0 mm (0.0394 in.)

  2. ROTATE TIRES


    1. A01MSFNC01
      *A except 18 Inch Wheel
      *B for 18 Inch Wheel
      B003XUN 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. A01MRLSC01
      *A for 16 Inch Wheel
      *B except 16 Inch Wheel
      *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


      • for 16 inch wheel: Use clip-on type balance weights for the inner side, and stick-on type balance weights for the outer side.

      • except 16 inch wheel: 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.
