Cold Tire Inflation Pressure (for TMMMS Made Sedan):

Tire Size	Cold Tire Inflation Pressure
Tire Size	Front	Rear
195/65R15 91S	260 kPa (2.6 kgf/cm², 38 psi)	250 kPa (2.5 kgf/cm², 36 psi)
205/55R16 91H	240 kPa (2.4 kgf/cm², 35 psi)	230 kPa (2.3 kgf/cm², 33 psi)
225/40R18 88V 225/40R18 88W	230 kPa (2.3 kgf/cm², 33 psi)	210 kPa (2.1 kgf/cm², 30 psi)
205/55R16 91V	220 kPa (2.2 kgf/cm², 32 psi)	220 kPa (2.2 kgf/cm², 32 psi)
225/45R17 91W	230 kPa (2.3 kgf/cm², 33 psi)	210 kPa (2.1 kgf/cm², 30 psi)

Cold Tire Inflation Pressure (for Compact Spare Tire):

Tire Size	Cold Tire Inflation Pressure
T125/70D17 98M	420 kPa (4.2 kgf/cm², 60 psi)

(1) Perform initialization.

for Gasoline Model (for Type A): Click here

for Gasoline Model (for Type B): Click here

(2) Tire pressure adjustment method when warm:

Turn the ignition switch (for Gasoline Model) or power switch (for HV Model) off.
Connect the Techstream to the DLC3.
Turn the ignition switch (for Gasoline Model) or power switch (for HV Model) 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.
for HV Model: Click here

for Gasoline Model (for Type A): Click here

for Gasoline Model (for Type B): Click here
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: P

P = (Specified Pressure) + (Ts - Tm)
Check the pressure adjustment value with the Data List item "Tire Inflation Pressure".

(b) Using a dial indicator, check the runout of the tires.

Maximum Tire Runout:

1.4 mm (0.0551 in.)

HINT:

Measure the runout with the wheel assembly removed from the vehicle.

2. ROTATE TIRES

(a) Remove the wheel assembly.

(b) except Mexico:

Front

(1) Rotate the tires as shown in the illustration.

(c) for Mexico:

Front

(1) Rotate the tires as shown in the illustration.

(d) Install the wheel assembly.

3. INSPECT AND ADJUST WHEEL BALANCE

(a) Inspect and adjust the off-the-car balance.

(1) for Steel Wheel:

Maximum Wheel Imbalance:

8.0 g (0.0176 lb)

HINT:

Use clip-on type balance weights for both the inner and outer side.
If the tires vibrate even after the off-the-car balance adjustment, adjust the wheel balance with on-the-car balancing as necessary.

(2) for Alloy Wheel (except 18 inch):

Maximum Wheel Imbalance:

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 balance weight.
Adhere a stick-on type balance weight to the flat surface*a shown in the illustration.
Push the balance weight with your finger to securely adhere it to the desired position.
Do not reuse balance weights.
Use only TOYOTA genuine stick-on type balance weights or equivalent.

HINT:

Use clip-on type balance weights for the inner side, and stick-on type balance weights for the outer side.
If the tires vibrate even after the off-the-car balance adjustment, adjust the wheel balance with on-the-car balancing as necessary.

*a	25 mm (0.984 in.)

(3) for Alloy Wheel (for 18 inch):

Maximum Wheel Imbalance:

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 balance weight.
Adhere a stick-on type balance weight to the flat surface*a shown in the illustration.
Push the balance weight with your finger to securely adhere it to the desired position.
Do not reuse balance weights.
Use only TOYOTA genuine stick-on type balance weights or equivalent.

HINT:

Use stick-on type balance weights for both the inner and outer side.
If the tires vibrate even after the off-the-car balance adjustment, adjust the wheel balance with on-the-car balancing as necessary.
