Inspection [09/2015 - ]: Procedure
- INSPECT TIRES
- Check the tires for wear and proper inflation pressure.

280 (2.9, 41)*2T165/80D17 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)
- Tire pressure adjustment method when warm:
- Turn the engine switch off.
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
- Adjust the tire pressure so that the displayed value is equal to the set pressure.
- Perform initialization and check that initialization completes.
Refer to INITIALIZATION [09/2015 - 05/2019] , or refer to INITIALIZATION [05/2019 - ]
- Check and record the value of the Data List item "Temperature in Tire". (Ts)
- Check and record the ambient temperature during tire pressure adjustment. (Tm)
- 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)
- 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 - ]
- Tire pressure adjustment method when warm:
- 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.
- Check the tires for wear and proper inflation pressure.
- ROTATE TIRES
- Remove the wheel assembly.
Refer to REMOVAL [10/2014 - ]
- Rotate the tires as shown in the illustration.
*a Front of the Vehicle - Install the wheel assembly.
Refer to INSTALLATION [10/2014 - ]
- Remove the wheel assembly.
- INSPECT WHEEL BALANCE
- 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.
- Check and adjust the off-the-car balance.
- INSPECT FRONT AXLE HUB BEARING LOOSENESS
Refer to ON-VEHICLE INSPECTION [10/2014 - ]
- INSPECT FRONT AXLE HUB RUNOUT
Refer to ON-VEHICLE INSPECTION [10/2014 - ]
- INSPECT REAR AXLE HUB BEARING LOOSENESS
Refer to ON-VEHICLE INSPECTION [10/2014 - 07/2020] , or refer to ON-VEHICLE INSPECTION [07/2020 - ]
- INSPECT REAR AXLE HUB RUNOUT
Refer to ON-VEHICLE INSPECTION [10/2014 - 07/2020] , or refer to ON-VEHICLE INSPECTION [07/2020 - ]
