TIRE / WHEEL: TIRE AND WHEEL SYSTEM: INSPECTION

1. INSPECT TIRES
(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 of above 160 km/h (100 mph), in countries where such speeds are permitted by law, inflate the front and rear tires to 310 kPa (3.1 kgf/cm2, 45 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.
Maximum tire runout:
1.0 mm (0.0394 in.)
2. ROTATE TIRES






(a) The tire size is different between front and rear and also the wheel design is different between left and right. Therefore, a tire rotation cannot be performed on this vehicle.
HINT: Identification marks are stamped on the back of a spoke of each wheel to indicate the installation position on the vehicle.





3. INSPECT WHEEL BALANCE






(a) Check and adjust the off-the-car balance.
Maximum imbalance after adjustment:
8.0 g (0.0176 lb.)
NOTICE:
- 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.
HINT: If necessary, check and adjust the on-the-car balance.
