Keep your tyre pressures at the proper level.
The recommended cold tyre pressures and tyre sizes are given in Part 8.
You should check the tyre pressures every two weeks, or at least once a month. And don't forget the spare!

Incorrect tyre pressure can reduce tyre life and make your vehicle less safe to drive.
Low tyre pressure results in excessive wear, poor handling, reduced fuel economy, and the possibility of blowouts from overheated tyres. Also, low tyre pressure can cause poor sealing of the tyre bead. If the tyre pressure is excessively low, there is the possibility of wheel deformation and/or tyre separation.
High tyre pressure produces a harsh ride, handling problems, excessive wear at the center of the tyre tread, and a greater possibility of tyre damage from road hazards.
If a tyre frequently needs refilling, have it checked by your Toyota dealer.

The following insturctions for checking tyre pressure should be observed:

  • The pressure should be checked only when the tyres are cold. If your vehicle has been parked for at least 3 hours and has not been driven for more than 1.5 km or 1 mile since, you will get an accurate cold tyre pressure reading.
  • Always use a tyre pressure gauge. The appearance of a tyre can be misleading. Besides, tyre pressures that are even just a few pounds off can degrade handling and ride.
  • Do not bleed or reduce tyre pressure after driving. It is normal for the tyre pressure to be higher after driving.
  • Be sure to reinstall the tyre inflation valve caps. Without the valve caps, dirt or moisture could get into the valve core and cause air leakage. If the caps have een lost, have new ones put on as soon as possible.
