●If the vehicle does not drive straight or you feel a pull throu gh the
steering wheel, stop the vehi cle and check the following.
• Tire condition. The tire may have separated f rom the wheel.
• Tire inflation pressure. If the tire inflation pressure is 19 p si
(130 kPa, 1.3 kgf/cm

NOTICE
■When performing an emergency repair
●A tire should only be repaired with the emergency tire puncture repair
