Component Tests and General Diagnostics
INSPECTION1. INSPECT TIRE
(a) Check the tires for wear and proper inflation pressure.
Cold tire inflation pressure:
When driving under the above vehicle conditions at sustained high speeds above 160 km/h (100 mph), in countries where such speeds are permitted by law, inflate the front and rear tires to 240 kPa (2.4 kgf*cm2, 35 psi) provided that it does not exceed the maximum cold tire inflation pressure molded on the tire sidewall.
(b) Using a dial indicator, check the runout of the tires.
Tire runout: 1.4 mm (0.055 in.) or less
2. ROTATE TIRES
(a) Rotate the tires as shown in illustration (A). If the vehicle is equipped with a grand spare tire, rotate the tires as shown in illustration (B).
3. INSPECT WHEEL BALANCE
(a) Check and adjust the off-the-car balance.
Imbalance after adjustment: 8.0 g (0.018 lb.) or less.
NOTICE:
^ Remove dirt, oil, and water from the surface where the balance weight is to be adhered with a cleaning detergent.
^ Do not touch the sticking surface of the tape.
^ Adhere the sticking type balance weight to the flat position shown in the illustration.

^ Do not reuse balance weights.
^ Use the LEXUS genuine adhesive type balance weights.
HINT:
^ The inner side balance weight should be installed by clipping it to the rim.
^ If necessary, check and adjust the on-the-car balance.
