Lexus NX: Inspection
INSPECTION
PROCEDURE
1. INSPECT TIRES
(a) 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 |
*1: For driving at under 160 km/h (100 mph)
*2: For driving at over 160 km/h (100 mph)
Specified Pressure (When Tire is Cool) (for Compact Spare Tire):
Tire Size | kPa (kgf/cm2, psi) |
T165/80D17 104M | 420 (4.2, 60) |
(1) Tire pressure adjustment method when warm:
-
Turn the power switch off.
-
Connect the Techstream to the DLC3.
-
Turn the power 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.

-
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 |
NOTICE:
Check the tire pressure warning system description for the relationship between the inflation pressure and tire pressure warning pressure.

(b) 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. | |
2. ROTATE TIRES
(a) Remove the wheel assembly.
Click here
(b) Rotate the tires as shown in the illustration. | |
(c) Install the wheel assembly.

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 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.
