    2. A01GHKB

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

      Tire runout
      1.0 mm (0.0394 in.) or less

      Tech Tips

      Remove the wheel assembly from the vehicle, and measure the wheel assembly alone.

  2. ROTATE TIRE


    1. A01GLJBE01
      Text in Illustration
      *A w/ Spare Tire
      *B w/o Spare Tire
      *a Front of the Vehicle

      Rotate the tires as shown in the illustration.

      Torque:
      140 N*m  { 1428 kgf*cm, 103 ft.*lbf }

      Tech Tips

      When a tire rotation is performed on a vehicle that has different specified tire pressures for the front and rear of the vehicle, it is necessary to perform initialization for the tire pressure warning system Click here.

  3. INSPECT WHEEL BALANCE


    1. A01GM1QE01

      Check and adjust the off-the-car balance.

      Maximum imbalance after adjustment
      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 sticking surface of the tape.

      • Adhere a sticking type balance weight to the flat surface (A) shown in the illustration.

        Width (A)
        25 mm (0.984 in.)

      • Push the balance weight firmly to adhere it to the position.

      • Do not reuse the balance weight.

      • Please use the LEXUS genuine sticking type balance weight.

      Tech Tips

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