TIRE AND WHEEL SYSTEM INSPECTION


  1. INSPECT TIRES


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

      Cold Tire Inflation Pressure
      Tire Size

      Cold Tire Inflation Pressure

      kPa (kgf/cm2, psi)
      Front Rear Front Rear
      225/40R19 93Y 255/35R19 96Y

      320 (3.2, 46)*1

      300 (3.0, 44)*2

      250 (2.5, 36)*3

      *1: For driving at over 250 km/h (155 mph).

      *2: For driving at 210 km/h (131 mph) to 250 km/h (155 mph).

      *3: For driving at under 210 km/h (131 mph).

    2. A0162H4

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

      Maximum tire runout
      1.0 mm (0.0394 in.)

  2. ROTATE TIRES


    1. A015ZPP

      When the design of the left and right side wheels is the same:


      1. Tire rotation cannot be performed on this vehicle.

    2. A0162E2E01

      When the design of the left and right side wheels is different:


      1. A0161N0E01

        Tire rotation cannot be performed on this vehicle.

        Tech Tips

        Identification marks are stamped on the back of a spoke of each wheel to indicate the installation position on the vehicle.

        Identification Mark Installation Position on Vehicle
        FL Left front wheel
        FR Right front wheel
        RL Left rear wheel
        RR Right rear wheel

  3. INSPECT WHEEL BALANCE


    1. A0160P4E01

      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 adhesive 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 securely with your finger to adhere it to the position.

      • Do not reuse the balance weight.

      • Use the LEXUS genuine sticking type balance weights.

      Tech Tips

      If necessary, check and adjust the on-the-car balance.
