Inspection [09/2015 - ]: Procedure

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

   Specified Pressure (When Tire is Cool)

   Tire Size	Front kPa (kgf/cm2 , psi)	Rear kPa (kgf/cm2 , psi)
   225/65R17 102H	240 (2.4, 35)*1 250 (2.5, 36)*2	240 (2.4, 35)*1 250 (2.5, 36)*2
   225/60R18 100H	220 (2.2, 32)*1 280 (2.9, 41)*2	220 (2.2, 32)*1 280 (2.9, 41)*2
   235/55R18 100V	220 (2.2, 32)*1 280 (2.9, 41)*2	220 (2.2, 32)*1 280 (2.9, 41)*2
   T165/80D17 104M	420 (4.2, 60)

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

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

   1. Tire pressure adjustment method when warm:
      1. Turn the engine switch off.
      2. Connect the Techstream to the DLC3.
      3. Turn the engine switch on (IG).
      4. Turn the Techstream 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.

         Refer to INITIALIZATION [09/2015 - 05/2019] , or refer to INITIALIZATION [05/2019 - ]

      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)

          HINT: 

          Tire internal temperature: Ts, Ambient temperature: Tm, Tire pressure readjustment value: PP = (Specified Pressure) + (Ts - Tm)

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

      Chassis > Tire Pressure Monitor > Data List 

      Tester Display
      ID 1 Tire Inflation Pressure
      ID 2 Tire Inflation Pressure
      ID 3 Tire Inflation Pressure
      ID 4 Tire Inflation Pressure

      NOTE:

      Check the tire pressure warning system description for the relationship between the inflation pressure and tire pressure warning pressure.

      Refer to SYSTEM DESCRIPTION [09/2015 - 05/2019] , or refer to SYSTEM DESCRIPTION [05/2019 - ]

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

   Tire runout

   1.4 mm (0.0551 in.) or less

   HINT: 

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

1. Remove the wheel assembly.

   Refer to REMOVAL [10/2014 - ]

2. Rotate the tires as shown in the illustration.

3. Install the wheel assembly.

   Refer to INSTALLATION [10/2014 - ]

1. 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.

   HINT: 

   • The inner side balance weights should be installed by clipping them to the rim.
   • If the tires vibrate even after off-the-car balance adjustment, adjust the wheel balance with on-the-car balancing as necessary.
