• Always check and adjust tire pressure before delivering a new vehicle or maintenance-performed vehicle to

the customer.

• Fill nitrogen gas into the tires.
• Set the nitrogen gas pressure as follows:

Front tire: 200 kPa (2.0 kg/cm

2

, 29 psi)

Rear tire: 200 kPa (2.0 kg/cm

2

, 29 psi)

• Before high performance driving, tire inner pressure is recommended to be adjusted under normal tempera-

ture as follows:

- Front wheel: 210 – 220 kPa (2.1 – 2.2 kg/cm

2

, 30 – 32 psi)

- Rear wheel: 200 kPa (2.0 kg/cm2, 29 psi)
• An internal pressure of tires is reduced depending on changes in

air temperature and altitude, or a temporal change. Driving a vehi-
cle with the tire pressure low is dangerous and may damage tires.
Therefore, it is required to periodically set tire internal pressure to a
specified value. Refer to 

WT-13, "Tire"

.

INSPECTIONS REQUIRED FOR BEFORE AND AFTER SPORTS DRIVING

• Immediately after installing tire to wheel, the tire does not fit sufficiently with the wheel. This may cause a

deviation in matching mark position of rotation direction. Never place a burden on tires (e.g. performance
driving) particularly for two days after tire change.

• Check for tire internal pressure and the positioning (rim deviation) in rotational directions for wheels and

inner tires.

• Check wheel lock nuts, the valve nut and valve core of the transmitter of the tire inflation pressure warning

system for looseness.

• Tighten up wheel lock nut within tightening torque of 147.1 N·m (15 kg-m, 109 ft-lb) before and after sports

driving.

• Check tires for deformation, cracks and other damage.
• Before high performance driving, tire inner pressure is recommended to be adjusted under normal tempera-

ture as follows:

- Front wheel: 210 – 220 kPa (2.1 – 2.2 kg/cm

2

, 30 – 32 psi)

- Rear wheel: 200 kPa (2.0 kg/cm2, 29 psi)
• To prevent the balance weight of tire wheel from being flaked, make sure to apply aluminum tape over the

balance weight, when driving at a high speed, over 200 km/h (124 MPH), and/or prior to circuit driving.

• To prevent wheel cap from coming off, remove it or fix it with a tape before driving.
