TIRE AND WHEEL SYSTEM INSPECTION

Info Added 2017-10-06

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
      215/65R16 98H

      230 kPa (2.3 kgf/cm2, 33 psi)

      230 kPa (2.3 kgf/cm2, 33 psi)
      215/60R17 96H

      230 kPa (2.3 kgf/cm2, 33 psi)

      230 kPa (2.3 kgf/cm2, 33 psi)
      225/50R18 95V

      230 kPa (2.3 kgf/cm2, 33 psi)

      230 kPa (2.3 kgf/cm2, 33 psi)
      Cold Tire Inflation Pressure (for Compact Spare Tire)
      Tire Size Cold Tire Inflation Pressure
      T145/90D16 106M

      420 kPa (4.2 kgf/cm2, 60 psi)
      T145/70D18 107M

      420 kPa (4.2 kgf/cm2, 60 psi)

      1. Perform initialization.

      2. Tire pressure adjustment method when warm:


        1. Turn the ignition switch off.

        2. Connect the GTS to the DLC3.

        3. Turn the ignition switch to ON.

        4. Turn the GTS on.

        5. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

        6. Adjust the tire pressure so that the displayed value is equal to the set pressure.

        7. Perform initialization and check that initialization completes.

        8. Check and record the value of the Data List item "Temperature in Tire". (Ts)

        9. Check and record the ambient temperature during tire pressure adjustment. (Tm)

        10. Readjust the tire pressure according to the difference between the tire internal temperature (Ts) and the ambient temperature (Tm). (P)

          Tech Tips

          Tire internal temperature: Ts, Ambient temperature: Tm, Tire pressure readjustment value: P

          P = (Specified Pressure) + (Ts - Tm)

        11. Check the pressure adjustment value with the Data List item "Tire Inflation Pressure".

        Note

        for ECE-R64 Type:

        If the tire pressure is decreased approximately 20 kPa (0.2 kgf/cm2, 2.9 psi) or more in order to adjust the tire pressure, even if the adjusted tire pressure is 80% or more than the tire pressure set during system initialization, the tire pressure warning light may illuminate if the tire pressure drops below 80% of the tire pressure set when the tires are warmed. In this case, perform initialization again.

    2. A001YF0

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

      Maximum Tire Runout
      1.4 mm (0.0551 in.)

      Tech Tips

      Measure the runout with the wheel assembly removed from the vehicle.

  2. ROTATE TIRES


    1. Remove the wheel assembly.

    2. A001WUAC02
      B00495X Front

      If the spare tire uses a different type of wheel than the other tires, rotate the tires as shown by (A) in the illustration. If the spare tire has the same type of wheel as the other tires, rotate the tires, including the spare tire, as shown by (B) in the illustration.

    3. Install the wheel assembly.

    4. Perform initialization.

  3. INSPECT AND ADJUST WHEEL BALANCE


    1. Inspect and adjust the off-the-car balance.


      1. A001VCN

        for Steel Wheel:

        Maximum Wheel Imbalance
        8.0 g (0.0176 lb)

        Tech Tips


        • Use clip-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.

      2. A001UDUC01
        *a 25 mm (0.984 in.)

        except Steel Wheel:

        Maximum Wheel 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 TOYOTA genuine stick-on type balance weights or equivalent.

        Tech Tips


        • Use clip-on type balance weights for the inner side, and stick-on type balance weights for the 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.
